processing technology of copper concentrates

Copper Concentrate an overview ScienceDirect Topics

The pulp from this grinding process is introduced into a floating process to which water and chemical reactants are added. This process results in a collective concentrate, Cu-Mo, containing approximately 30% copper and 1% molybdenum. In a follow-up process, the copper and sulfur-molybdenum concentrate are separated.

Case Study Flowsheets: Copper–Gold Concentrate Treatment

Jan 01, 2016· CESL Copper Process (Mayhew et al., 2013). The CESL Copper Process uses chloride-catalyzed leaching of copper concentrates in a predominantly sulfate solution at 150 °C followed by copper solvent extraction and electrowinning. The CESL Copper Process was installed by Vale at the UHC plant site in Brazil as a 10,000 tpa demonstration facility.

From Ore to Finished Product Copper

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.
