Treatment Methods of Lead & Zinc Ore

Lead and Zinc Ores Minerals of lead and zinc commonly are rather closely associated in nature; zinc-free lead ores and lead-free zinc ores are exceptional rather than common, although there are such. Lead and zinc ores usually contain some silver, but those of the Mississippi Valley region are silver-free. Indeed, lead-zinc ores often are commercially valuable chiefly because of their silver

Underground Mining Methods of Zinc Ore

Heavy-duty, durable and compact mining equipment has increased cost-effectiveness and the efficiency with which we mine. As a result, the mining industry has been able to reduce waste, as well as dangerous chemicals.
determination of Bond rod-mill work index by

The grinding experiments were carried out on four typical samples of iron, copper, manganese and lead–zinc ore with three test-sieves in specified time periods and aimed to shortening the procedure. Furthermore, the grinding kinetics and mass balance equations were applied to model the standard Bond rod-mill work index.
