Slovakia is a country with a very fast-growing automotive industry. In 2016 in Slovakia more then one million cars were made. Slovakia ranks first with the production of 183 cars per 1,000 citizens. Cars production is closely linked to the castings and machines production. Slovak foundry industry is currently primarily focused on castings for various cars brands. Many cars producers today require not only a declaration of castings production quality but also declaration of minimalization the impact of their production on the environment.
Given contribution deals with an analyse of the impact of steel and cast iron castings production on the environment and complex treatment of wastes originating in the castings production. Steel and iron castings production is connected with the origin of three main types of wastes: dust, slag and used sand and core mixtures. Dust is generated at all stages of castings production from charging in to the melting aggregate, through melting, casting, and machining of castings. The type and amount of slag depends on the melting unit. Used sand and core mixtures feature the largest share of wastes from the castings production.
This paper will discuss the possibilities of processing these three basic wastes and their reusing in production process in foundry.

Recently, the extraction behavior of rare earth elements(REEs) contained in permanent magnets has been studied by hydrometallurgical using chemical solutions and pyrometallurgical process using molten magnesium.
In order to explore new and better extractant in pyrometallurgical process, the authors used molten bismuth.
To investigate the characteristics of diffusion in REEs(Nd, Dy)-Bi couple, an assessment of both reaction and diffusion of Nd and Dy in molten bismuth was carried out. For identification of the reaction mechanism, the effects of experimental parameters such as temperature (range of 573K to 973K) and holding time (from 0 to 24hour) were investigated. Diffusion of REE from the Nd-Fe-B magnet into molten Bi was found to occur at a higher rate than molten Mg, and the reaction rate was varied depending on the temperature and time. The diffusion behaviors were analyzed by Scanning Electron Microscopy (SEM) and Energy Dispersive Spectroscopy (EDS), and the constituent phases were characterized using X-Ray Diffraction (XRD). It was found out that 500�E is the critical temperature for extraction and diffusion of REE(Nd, Dy) by Bi.

Ferronickel slags, due to their physicochemical characteristics, have good potential to improve the performance of construction materials when properly and adequately used as a component in these materials. As such, instead of being a waste that harms the environment, they can be turned into valuable materials for the construction industry assuring an efficient use of resources. As part of a bigger cooperation project with FLOGEN Technologies Inc. this paper gives the results of an investigation on the use of ferronickel slags from Ferronickel Company in Kosovo in several construction materials such as cement, asphalt, concrete, etc. The goal of the project is to determine the best recipes for the optimal use of the ferronickel slags in the construction materials in order to achieve their best physico-mechanical properties. Based on numerous laboratory analysis various mixture ratios of slag in the construction products have been studied followed by laboratory examination of the physical-mechanical properties of the corresponding mixtures. It was found that the use of ferronickel slag from Ferronickel Company can be beneficial to improve the mechanical and physical properties of all construction materials and at the same time protect the environment by turning a waste of metallurgical industry in a useful primary material for the construction industry.

In this work, the experimental results of the treatment at pilot scale of photovoltaic panels of different technologies were reported. The recycling route includes a sequence of mechanical and chemical operations in order to recover glass and other useful materials. After mechanical treatment, ground material is sieved and only the coarse fraction is treated by solvent treatment in order to have the detachment of panel fragments into different components: solar grade glass, metallic filaments, back sheet foils (Tedlar), polymeric gluing components (EVA aggregates). The fine fractions emerging from mechanical treatment is treated by acid leaching in order to remove metals and obtain another recoverable glass powder. Recycling rate of the demonstrated process was 80% and 85% for Si based panels and CdTe panels, respectively.

Due to the increasing demand of electronic devices the amount of waste electrical and electronic equipment (WEEE) continuously rises. Therefore suitable recycling processes are essential in order to treat such 'End of Life' - products. The necessity is given on the one hand on the valuable and also critical containing metals (such as copper and the precious ones) and on the other hand on hazardous substances (like brominated flame retardants), which might be manufactured in these appliances.
Pyrometallurgical melting procedures represent one possibility for a proper recycling. A big environmental problem lies in the fact that with usage of a direct incineration the hazard of the formation of dangerous halogenated dioxins and furans is given, which can be avoided by a previous pyrolysis step or a proper post-combustion.
The product of such processes are metallic, slag and gaseous phases. The less noble elements form an oxidic slag phase. Due to the fact that this by-product might contain a lot of various elements (like iron, silicon, aluminum, calcium, etc) depending on diverse process conditions an appropriate investigation is necessary. This includes the different containing phases as well as the melting behavior in order to implicate a suitable treatment of such a slag.

The recycling of hazardous metallurgical waste, such as jarosite, a precipitation residue from the hydrometallurgical zinc winning route and electric arc furnace dust (EAFD) from the iron and steel industry displays one aim for the future to open up new chances for secondary resources and to avoid landfilling. More than 50 % of the worldwide production of EAFD and the majority of the jarosite are still dumped, although there are valuable metals, such as zinc, lead, indium, silver and iron present in these by-products.
Since the EAFD and the jarosite represent a high economical potential, a metal bath process offers a possibility to reprocess both residues together and to achieve a multi-metal recovery. The advantages of the process are that two residues can be treated together to recover valuable metals, while at the same time no more dumping of the waste is necessary. The products of the process include a metal-bearing off-gas, an iron alloy as well as a slag. This paper describes the concept of the developed metal bath process and shows first results of carried out lab-scale trials.

In this work, the overall process for the treatment of LIB was presented considering both the mechanical step for the recovery of black mass, and the hydrometallurgical route for the recovery of metals. Black mass, recovered with high yield and purity by shredding, sieving and milling, was fed to leaching reactor for dissolving all metals (Li, Mn, Co, Ni) giving a residue which can be recovered as pure graphite. Co can be recovered as salt or oxide after precipitation by pH increase for metal impurity separation, or after solvent extraction achieving commercial purity. After separation of sodium, Li can be recovered as carbonate.

Separation of REEs from fluorescent lamp waste has been a very successful project financed by Formas and Energimyndigheten between 2010-2014, aimed at recycling of Rare Earth Metals (REMs) from low energy lamps after Hg decontamination step. The project has been carried-out in close collaboration with an industrial partner (Nordic Recycling AB), CIT (Chalmers Industritechnik) and IVL (Swedish Environmental Research Institute).
A hydrometallurgical process was developed, comprising a leaching step for mercury (using iodine solutions) and subsequent selective leaching of remaining components. The hydrometallurgical decontamination process can be viewed as a simpler and possibly cheaper alternative to the energy intensive thermal treatment for reducing mercury levels in heavily contaminated samples. Cyanex 923 in kerosene allows the separation of REEs from other elements, leading to significantly better results compared to other extraction systems e.g. TBP. Separation of a REEs concentrate was achieved using mixer settlers. From here, the stream can be further processed for further separation using e.g. more selective extractants or a larger number of extraction stages. In December 2014, the project has reached the laboratory pilot stage.
Due to the success of the project, the industrial partner together with other 3 SMEs (MEAB, MRT and CIT) and Chalmers group have decided on scaling-up the project and installing a pilot plat at the industrial partner�s site. The whole process makes the subject of this work.

Recycling is becoming a more and more important resource of metal. In electronics and car recycling, this mainly applies to copper, iron, steel, lead, aluminum, and gold.
The combustion processes in the metal recycling process are a large user of energy and source of emissions. There are two main ways to save energy and reduce emissions in those processes: the Direct Way �C the most efficient ways to save energy and decrease emissions are to minimize the need and the generation, respectively; the Indirect Way �C energy recycling and post treatment to remove CO2, NOx, SOx, etc.
There is large short-term opportunity to decrease energy use and emissions from the metal recycling industry sector by using the Direct Way. It has been proven that the need for energy in many of these combustion processes can be reduced by 20-50% by applying different types of oxyfuel combustion �C an excellent example of the Direct Way. Reduction of CO2 emissions will follow the reduced energy need. A special combustion technology called Flameless Oxyfuel is also very efficient to reduce NOx emissions. Linde��as a global leading industry gas company, has pioneered the development and implementation of flameless oxyfuel technology in the copper, lead and aluminum recycling industries. Flameless Oxyfuel provides an overall thermal efficiency in the heating of 80%; the commonly used air-fuel that reaches 40-60%. With Flameless Oxyfuel, compared to air-fuel, the energy savings are at least 25%, but many times 50% or even more. The corresponding reduction in CO2 emission is also 25-50%. Savings in terms of NOx emissions are substantial, sometimes exceeding 90%. Flameless Oxyfuel combustion has major advantages over conventional oxyfuel and, even more, over any kind of air-fuel combustion. The improved temperature uniformity is a very important benefit, which also reduces the fuel consumption further.
Over the past decades, there were many hundreds of successful installations of different oxygen and oxyfuel solutions in the metal recycling industry sector, all resulting in reduced fuel consumption and less emissions. Here follows are examples: OXYGON vessel preheating, Flameless Oxyfuel for copper and lead recycling, LTOF for aluminum recycling; Installations of OXYGON, LTOF and have demonstrated reductions of the hazardous NOx emissions by 60-95%.
Flameless Oxyfuel solutions are creating benefits for the metal recycling industry sector in terms of cost savings and improved working environment, but also for the society as a whole. This is particularly important in Asia, with both a large population and a huge heavy industry production. These well-established technologies can strongly support a quick path to make the metallurgical processes in the metal recycling industry ��green��!

Electric-arc furnace dust (EAFD), containing Zn more than 20%, is prospective raw-material for zinc, lead, and other valuable components recovery. Pyrometallurgical EAF dust treatment has low selectivity, poor quality final products, high consumption of carbon reducing agent, and environmental hazards. The presence of high ferrite and impurities, especially halides, don’t allow wide applications of hydrometallurgical methods. To increase zinc extraction at the stage of leaching, it is necessary to develop processes of EAF dust pretreatment for the purpose of ferrite destruction and halides removal. The most rational variant is the two-stage EAF dust Waelz process, with chlorides vaporization and production of zinc-containing calcined by-products. Alkaline leaching of such material allows to selectively recover zinc into concentrated solutions. It allows to produce high-quality zinc powders. This process requires minimum capital and operating costs, and has minimum influence on the environment.

LD slag (Linz Donawitz slag) is one of the major industrial by-products generated during steel making in the integrated Tata Steel plant at Jamshedpur, Jharkhand, India. The plant uses approximately 25 million tons of iron ore and coal/coke blend every year to produce about 10 million tons of steel. Hot metal or molten iron from the blast furnace is transferred into vessels called torpedoes and transported on rail tracks to the LD shops. Here, the molten iron is refined into steel using the ‘basic oxygen furnace’ (BOF) method. In a steel industry, all the three types of waste materials (gaseous, liquid and solid) are generated. The generation of gaseous waste material is the highest, but the management of solid waste material is the most intricate. The steel slag generated from LD converter (steel making) is dumped in pits and allowed to cool by sprinkling water. The solidified steel slag is then sent to a waste recycling plant (WRP) for recovery of the metallic and non-metallic portions. The quantity of non-metallic portion of (-6.0mm) LD Slag fines after the recovery of metallic portion is around 40000MT/Month, which is close to 5 Lakh tons per annum. The present study aims at value addition of this enormous amount of non-metallic slag by a chemical process to obtain “yellow gypsum”, which has a wide range of industrial and agricultural applications. The authors have characterized this material using techniques such as x-ray diffraction (XRD), chemical analysis, scanning electron microscopy (SEM), thermogravimetric analysis (TGA), Fourier transform infrared analysis (FTIR), and Raman spectroscopy. The authors have also discussed the applicability of this material for different applications. An Indian patent application (572/KOL/2014) has been filed for this material.

The hydrogenation of unsaturated compounds is a key technology in the chemical industry. The efficient catalytic reduction of water for generation of hydrogen is one of the most challenging transformations in chemistry.
We continuously investigated the potential application of iron (commercial iron powder) to activate water as a terminal hydrogen source without any stoichiometric acid or base. Here in we are pleased to disclose the external-pressure-free and mild reaction protocol for reduction of alkenes using a cheap, non-hazardous, abundant, and eco-friendly ��water/iron�� pair as a hydrogen donor in the presence of a Pd/C catalyst (2.5 mol % w.r.t. substrate).
Pd/C-catalyzed hydrogenation of olefins by using water as a hydrogen source in the presence of iron powder gave the corresponding reduction products in �� 96% yield (GC Yield). The formation of Fe3O4 as a byproduct was confirmed by XRD analysis.
