Apr 18, 2019018332Once a metal sulphide deposit has been identified, drilled out and a resource calculated a feasibility study will be carried out to determine whether it can be mined economically. It will be decided how the deposit is to be mined open cast or underground mining. During the mining operation, only the ore of a certain grade will be processed.Read More
History of Sulphide ore flotation dates back to beginning of 20th century. Sulphide ores are major sources of base metals like Copper, Lead, Zinc, Nickel, Cobalt etc. Beneficiation of these base metal sulphide minerals is predominating through froth flotation technique. This technology has acclaimed importance as a versatile process forRead More
In order to minimize the adverse impacts of mining it is desirable to adopt eco-friendly mining technology. The low grade ores can be better utilised by using microbial leaching technique. The bacterium Thiobacillus ferroxidans has been successfully and economically used for extracting gold embedded in iron sulphide ore.Read More
