EXTRACTION OF MOLYBDENUM FROM SULFIDE ORES OF THE SHANTOBE DEPOSIT USING CULTURE ACIDOTHIOBACILLUS FERROOXIDANS
Abstract
A large number of precious metals such as molybdenum, gold, uranium and much more are obtained from sulfide ores. Currently, a large number of hydrometallurgical methods are used to extract precious metals, which in turn are outdated in this field. In this regard, it is necessary to develop new modern methods for extracting all valuable components from sulfide ores. One of these methods is the process of bio-leaching with the use of microorganisms. The use of this method in mining companies will help reduce the risk of environmental pollution, and there is also an economic benefit associated with the involvement of recycling of waste from mining companies. This article describes the granulometric analysis of molybdenum ore from the Shantobe Deposit. When the ore was sifted, it turned out to be of 9 classes of size. Study of the chemical analysis of the solution of the Evaporation map No.5 for the content of chemical elements in it. The use of acidophilic culture Acid.ferrooxidans, which was produced using the nutrient medium Silverman - Lyngren (9K).The growth of this microbiological culture was judged by the change in color to brown, which indicated that the solution contains Fe3+.
