From Ore to Finished Product Copper

Copper ore is extracted using two basic methods of mining open pit or underground mining. 3. Processing of Copper Ore The first step in processing the ore removed from the mine is to break the large rocks of ore into smaller pieces. This is accomplished by a variety of subsequent processing steps. 4. Beneficiation of Copper Ore

Mining Process Konkola Copper Mines Plc

Since inception of the mine, refractory ore from the copper production process was surface stockpiled. KCM has now developed a process to extract copper from the refractory ore stockpile. The company also produces several by-products, including sulphuric acid produced from the smelting process, which is largely consumed in the leaching process.

Copper Production: How Is Copper Made? ThoughtCo

2019-9-26  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.

TENORM: Copper Mining and Production Wastes US EPA

2021-6-7  Ores that contain copper in the U.S. are typically mined in large, open-pits. Copper processing facilities are usually located near mining or extraction sites. Significant waste volumes are associated with copper production. Mine wastes may contain radionuclides due to their natural presence in ores and can be a source of TENORM.
