Paper Id: 472
[Abstract] Producing concentrates from graphite ores with the highest possible grade of graphite flakes is an important goal to increase the efficiency of the use graphite ores in the framework of sustainability. Participating in Balama Graphite Project from Syrah Resources Company in Mozambique, Fundação Gorceix, through its Mining and Metallurgy Department carried out initial characterisation of graphite ores, carried out bench test works in laboratory and pilot plants using a large sample of graphite ore provided by the company. As a result, it was possible to obtain concentrates with a high grade of graphite flakes, above 93%, compatible with market demand for use in electric car batteries. The subsequent work included the definition of the process flowsheet adopted for the characteristics of the current industrial exploitation in Mozambique. This paper will present this work and the results achieved.

Paper Id: 473
[Abstract] Generating high iron containing concentrates is an important goal to ensure the efficiency of their Direct Reduction subsequent treatment in the framework of sustainability. This was the main objective of Fundação Gorceix when undertaking, through its Mining and Metallurgy Department two major industrial iron ore projects: (1) BAMIN's Pedra de Ferro project, which plans the production of 25 million tons of pellets per year, in the State of Bahia, outside the Ferriferous Quadrangle, with an expected start up in 2025 and (2) Compact Ores Arcelor Mittal project–Serra Azul Mine, in Minas Gerais state. During the course of the projects a complete research investigation was carried out including mineralogical characterization, bench scale tests and pilot plant studies. The major result of the work was the generation of a premium concentrate for Direct Reduction with iron content as high as 66.5% and with a high competitive metallurgical recovery. The industrial processing flowsheet in a compatible industrial metallurgical complex was also developed. This paper will present this work and the results achieved.

GENERATION OF COMMERCIAL LITHIUM CONCENTRATE FROM FELDSPHATE FLOTATION Fernando Jose Gomes1 ;
1Foundation Gorceix, Ouro Preto, Brazil;
Paper Id: 499
[Abstract] Producing concentrates from spodumene ores with the highest possible grade of lithium is an important goal to increase the efficiency of the use lithium ores in the framework of sustainability. Participating in Brazilian society project, Fundação Gorceix, through its Mining and Metallurgy Department carried out initial characterization of lithium ores, carried out bench test works in laboratory and pilot plants using a sample provided by the company. As a result, it was possible to obtain concentrates with a high grade of lithium, above 5,7%, (target 6,0%) compatible with market demand. The subsequent work included the simplification and proposition of the new industrial process flowsheet (flotation of micas/feldspathe has been excluded). This paper will present this work and the results achieved.
