Zinc mining - Wikipedia

More than 50 countries around the world mine zinc ore, with Australia, Canada, China, Peru and the USA being the largest producers. About 80 percent of the world's zinc is mined underground, while 8 percent is mined via open pits with the rest using a combination of both methods. Zinc mine operators include Xstrata,.

Silver Ore - The Mining Processes that Transform Ore into Bullion .

Dec 18, 2016 . In many places, silver ore is often found in combination with other ores containing other commercially viable minerals such as copper, lead or gold. When silver is a byproduct of processing these other minerals then a different method has to be used to extract the silver ore. For example is silver is found in.

Lead: smelting, producing and classification-Metalpedia

The majority of the deposits are mixtures of minerals, hence lead ore is usually obtained as a byproduct of other metal mining such as zinc, silver or copper. In fact . Roasting is a method where a sulfide ore (i.e an ore containing PbS) is heated in air which converts the metal sulfide to either a metal oxide or a metal itself.
