Copper Tailing an overview ScienceDirect Topics
Copper tailings are a finely ground waste after copper mineral has been extracted from the ores during beneficiation. Recovery Act, by the US Environmental Protection Agency in 1991, was based on the investigation of several industrial processing wastes, including CS, copper tailings and calcium sulphate wastewater treatment plant sludge

Tailings Copper Mountain Mining Corporation
Tailings are natural, finely ground rock or sand that remains after economic minerals have been removed. At Copper Mountain, the ore body is a low sulfidation, carbonate-hosted copper deposit. This is important as the naturally high percentage of carbonate, compared to the naturally low presence of sulfur, results in the tailings from our mine

26/09/2019 The remaining mixture is a molten copper sulfide referred to as matte. The next step in the refining process is to oxidize liquid matte in order to remove iron to burn off sulfide content as sulfur dioxide. The result is 97-99%, blister copper. The term blister copper comes from the bubbles produced by sulfur dioxide on the surface of the copper.

Copper Mining and Processing: Everything you Need to Know
The Basics of Copper Mining and Processing. Mined from open pits, copper ore must be crushed as part of the process that occurs between extraction and production. Using today’s compact mining equipment, copper ore is extracted from the mine. After the ore is crushed, it’s roasted, which helps to convert sulfides to oxides.
