Lead Concentrates;

The primary ore is galena or Lead sulphite PbS. This is unstable, and on prolonged exposure to the atmosphere it oxidizes into the minerals cerussite PbCO3 and anglesite PbSO4. Lead ores are usually associated with other metals, particularly silver .

Lead concentrate is an intermediate product used as raw material in the production of Pure Lead. Lead Alloys and Lead products. The quality of different lead concentrates can vary but sulphide concentrates typically contain lead and sulphur. 

Zinc Concentrates;

The Zinc concentrates usualy contains min 40 % Zn and  around 25-30 % Sulfur and different amounts of other elements and metals  such as Iron, Lead,Silver. Sphalerite (zinc sulfide) is the primary ore mineral from which most of the world’s zinc is produced, but a number of other minerals that do not contain sulfide contain zinc as a major component. Much of the early zinc production was from nonsulfide deposits; however, as these resources were exhausted, production shifted to sulfide deposits. In the past 30 years, advances in extractive metallurgy have resulted in renewed interest in nonsulfide zinc deposits. 

Chrome Ore &  Concentrates;

Chromite is a key industrial mineral primarily used for manufacturing stainless steel because of its very high melting point. It is the principle ore of the element chromium. The processing of chromite ore separates & concentrates the valuable chromite mineral. This involves mechanical processes & separation using gravity. The final product of the ore & concentrate is ferrochrome.

Through our marketing activities, we Buy/Sell Zinc ,Lead , Copper concentrates as well Chrome Ore and Concentrates.
