The USGS assessed undiscovered copper in two deposit types that account for about 80 percent of the world''s copper supply. Porphyry copper deposits account for about 60 percent of the world''s copper. In porphyry copper deposits, copper ore minerals are disseminated in igneous intrusions.
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.
The latest technology trends in mining indie a compelling industry shift towards sustainability. Digital technology works harder than ever to deliver a truly modern, safe, and productive mine that addresses the increased demand for mined materials, while at the same time exceeding customer expectations and global sustainability initiatives.
Apr 01, 2014 · New radio frequency plasma technology, which heats complex ores to over 8,000 degrees Celsius, freeing up hidden precious metals, could completely change the face of the mining industry, boosting yields of metals such as gold, silver and platinum from complex ores
Ore, a natural aggregation of one or more minerals that can be mined, processed, and sold at a profit. An older definition restricted usage of the word ore to metallic mineral deposits, but the term has expanded in some instances to include nonmetallics. Although more than 2,800 mineral species
Mineral processing. In the oredressing plant, the material received from the mine is crushed in several stages and finely ground to a size which ensures that copper minerals are liberated from the waste materials, or gangue cases where the next step is leaching (most frequently in the case of oxide ores), complete liberation of the copper minerals is not always necessary the ore needs to
The life cycle of mining begins with exploration, continues through production, and ends with closure and postmining land use. New technologies can benefit the mining industry and consumers in all stages of this life cycle. This report does not include downstream processing, such as smelting of

The production process of copper ore mainly include: crushing, grinding, ore dressing. In the crushing process, three crushing circuits are suitable for high hardness iron ore broken, which can complete the ore crushing and partial dissociation work so as to improve the efficiency of the subsequent grinding.
Lead/Zinc Ore. Lead and zinc often occur in the same ore. Copper is also present in some ores. Froth flotation is again employed to produce marketable concentrates of both. The process is identical in principle to the flotation of other minerals. The figure on the

Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century.
Copper is used in many different industries, including building construction, transportation, electronics and consumer goods. Minerals are concentrated in specific types of geologic formations (ore bodies), which are where mining takes place. These ore bodies may already contain naturallyoccurring radioactive materials (NORM).
