Copper Ore Processing Methods
Apr 11, 2017The four major steps in the production of marketable copper are mining, concentrating, smelting, and refining. In a few instances, however, leaching takes the place of concentrating, smelting, and refining. At present, although considerable leaching and direct-smelting ores are produced, the bulk of the copper ore mined is concentrated.

Chapter 8 Environmental Aspects of Copper Production
Uncontrolled copper smelting processes emit large quantities of particulate matter, trace ele- ments, and sulfur oxides, which can have adverse effects on human health. Sulfur dioxide (SO 2 ), and the sulfates and sulfuric acid aerosols it forms in the atmosphere, can be lung irritants and ag- gravate asthma.
