Lateritic nickel ore deposits

2019 6 3  Lateritic nickel ore deposits are surficial, weathered rinds formed on ultramafic rocks. They account for 73% of the continental world nickel resources and will be in the future the dominant source for the mining of nickel.

Biomining

2019 6 6  Biomining is a technique of extracting metals from ores and other solid materials typically using prokaryotes or fungi. These organisms secrete different organic compounds that chelate metals from the environment and bring it back to the cell where they are typically used to coordinate electrons. It was discovered in the mid 1900s that microorganisms use metals in the cell.

Copper Essential Chemical Industry

2019 6 12  Data from 1 International Copper Study Group, 2015. 2 U.S. Geological Survey, Mineral Commodity Summaries, 2016. Manufacture of copper. About 80% of the world's primary copper comes from ores in which copper is present as a sulfide mineral, for example, chalcopyrite (CuFeS 2) (the most abundant copper ore), bornite (Cu 5 FeS 4) and chalcocite (Cu 2 S). These ores contain typically only

GCSE CHEMISTRY Extraction of Copper Thermal

2017 3 27  Extraction of Metals. Extraction of Copper.. Copper is sometimes found as native metal.. Copper ores include copper(II) oxide and copper(II) sulfide. Copper(II) oxide can be reduced by reaction with carbon.. Some copper ores may contain only small amounts of copper. These are called low grade ores and have less than 1% copper but they are still used because copper is so valuable.
