LEAD ZINC EXTRACTION PROCESSES

2012-7-25  are used for production of lead zinc depending on the type of raw material used as a charge. In the pyrometallurgical process, ore concentrate containing lead, zinc, or both is fed, in some cases after sintering, into a primary smelter. Lead concentrations can be 50-70%, and the sulfur content of sulfidic ores is in the range of 15-20%.

What is Concentration of Ore? Definition, Physical ...

2 天前  In simple words, the concentration of ore is the method of separating ore from the gangue, as the gangue or matrix particles are the valueless substances that are of no use. The ore can be concentrated or separated by both physical and chemical means. The ore obtained after the completion of the ore concentration is called concentrate.

Mineral Processing and Metallurgical Treatment of

The metallurgical treatment of such bulk concentrates means a complex challenge for the extractive metallurgy. Another frequently described example is the presence of heavy gangue minerals in lead vanadate ore such as baryte (4.5 g/cm 3) or manganese/manganese-lead minerals. This results in a low-quality lead vanadate concentrate
