ABSTRACT In recent years, lead and zinc, emerge to become one of the most widely used non-ferrous metals for their growing demand in lead-acid batteries, galvanization, radio-active shielding, alloy, and pigments, etc. With continuous exploitation and expanding plant capacity, exhaustion of primary high-grade lead-zinc resources has …
Although a few copper elements exist in lead-zinc ore, the application of copper sulfate in beneficiation process results in the metal depletion corresponding to copper. Carbon dioxide, which is released from coal burning electricity generation and diesel combustion to air, is the dominate contributor for climate change.

More than 90% of nonferrous metal (copper, lead, zinc, etc.) ores are separated by flotation. Advantages and Disadvantages Flotation method has high separation efficiency. It can effectively separate low-grade ore into high-grade concentrate, especially for the ore with fine-grained distribution and complex composition.
Copper - From Beginning to End. Copper is a major metal and an essential element used by man. It is found in ore deposits around the world. It is also the oldest metal known to man and was first discovered and used about 10,000 years ago. And as alloyed in bronze (copper-tin alloy) about 3000 BC, was the first engineering material known to man.
