Abstract:
The recovery of non-ferrous and precious metals is an important and interesting topic due to the low stocks resources and high price, especially in the case of precious metals. Waste water and solutions from different industries can be a valuable source of these metals. However, processing waste solutions cause many problems, such as low concentration of metals in solution or different species of metals in one solution. For this purpose, conventional liquid waste processing technologies become economically viable.
Given the current economic situation and low stocks of the mentioned metals, finding suitable and cost-efficient technology is a top priority. The application of biotechnological methods to treat waste solutions can be an efficient and cost-effectively method to acquire different types of metals.
The present paper deals with the application of an innovative process based on biotechnological principles using special constructed reactor to recover and recycle metals from different waste solutions and waters. The process was primarily developed for gold and silver recovery from old mines wastewater and industrial solutions, but it is also suitable to recover non-ferrous metals like copper, zinc, nickel etc.
Initial experiments showed promising recovery rates for selected metals and for large scale industrial application in the future.
