    Oct 17, 2020· Sulfuric acid. Sulfuric acid is a toxic chemical used in copper mining. It is also a byproduct of many kinds of mining, mixing with water and heavy metals to form acid mine drainage. Sulfuric acid smells like rotten eggs. Contact with sulfuric acid can cause burns, blindness, and death.

    The modern froth flotation process was independently invented the early 1900s in Australia by C.V Potter and around the same time by G. D. Delprat. All primary sulfide ores of copper sulfides, and most concentrates of secondary copper sulfides (being chalcocite), are subjected to smelting. Some vat leach or pressure leach processes exist to solubilise chalcocite concentrates and produce copper cathode from the resulting leachatesoluti

    The Basics of Copper Mining and ProcessingWhat Is Copper Used forThe Copper Mining ProcessMined 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 oxides are smelted to produce matte, which then undergoes several refining processes.

Surface mining is used to excavate ores at or close to the earth’s surface ; underground and in situ mining both remove minerals from deeper deposits. Metallic minerals: include ores, such as bauxite from which aluminum is extracted copper, gold, iron, lead, silver, and zinc.

  • TENORM: Copper Mining and Production Wastes Radiation

    Mining and Processing MethodsWaste GenerationDisposal and ReuseEPA and The StatesOres 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. Uranium, which may be co-located with copper ore, may also be recovered as a side stream, if economical. However, in the United Stat

    At this stage of the process, the chemical reactions begin. They convert the copper minerals into copper metal. We can illustrate the types of process using the example of chalcopyrite CuFeS 2.From the formula, it is clear that iron and sulphur have to be removed in order to produce copper.

  • Toxic chemicals used in mining

    Toxic chemicals are used in the Flotation Process to separate the copper and molybdenum out of the milled powder. This Flotation process is the major extraction method at Duval/Sierrita mine because of the poor quality of the copper at this site. Some chemicals produce bubbles that that the copper adheres to and the "bad stuff" falls to the bottom.

    Mining copper About 200 years ago the UK was an important world source of copper and tin and there were mines in Cornwall and Devon. These mines have now closed and today the biggest copper mines are in Chile (Escondida mine) and Indonesia (Grasberg mine). These produce many millions of tonnes of copper ore per year.
