Enargite Treatments and Pressure Oxidation of Concentrates
並列摘要
Due to increasingly stringent worldwide environmental regulations for gaseous, aqueous and solid waste emissions, conventional smelting technology causes difficulties when treating materials containing arsenic. Many globally significant copper properties have copper sulfide mineralogy that has a high arsenic content present as enargite. Often, the enargite is present as very large resources with significant amounts of contained precious metals. As global copper, silver and gold demand increases while significant world resources decrease, treatment of sulfide orebodies with enargite is becoming increasingly important. A review of enargite treatment technologies are discussed as well as a basic overview of an evaluation of the selective dissolution and fixation of arsenic while leaving behind a clean copper and precious metals-bearing concentrate suitable as a smelter feed.
