Copper mining. Chemical reactions.
Copper mining. Chemical reactions. remove some of the sulphur as sulphur dioxide. We do this by heating the concentrated ore from froth floatation. It is heated to betweem 500 °C and 700 °C in air. The product from the roaster is called calcine. It is a solid mixture of oxides, sulphides and sulphates.
Copper Smelting
This reagent is widely used in the selective flotation of lead–copper–zinc and copper–zinc ores to depress sphalerite, pyrite, and certain copper sulfides. Sphalerite rejection from copper concentrates is often of major concern, as zinc is a penalty element in copper smelting. Cyanide chemistry is comprehensively reviewed by Guo et al ...

GCSE CHEMISTRY
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.
SXEW (solvent extraction and electrowinning) | KGHM ...
SXEW technology involves leaching (the process of dissolving useful ingredients with a solution) in atmospheric conditions of copper ore heaps by means of diluted sulphuric acid. Folowing leaching, the pregnant leaching solution is transported via a drainage system to the next stage. In an SXEW reactor, the first process to take place is solvent extraction, which involves setting and ...

Copper processing
Extraction and refining. The extraction of copper from ore is normally carried out in three major steps. The first step, mineral processing, is to liberate the copper minerals and remove waste constituents—such as alumina, limestone, pyrite, and silica—so that the copper minerals and other nonferrous minerals of value are concentrated into a product containing between 20 and 30 percent copper.

A major development in the world's platinum industry took place in the early nineteen twenties when large deposits of platinum bearing ore were discovered in the Transvaal in South Africa. This led to the formation in 1931 of Rustenburg Platinum Mines Limited to work these deposits, and this company remains to this day the only platinum producer in South Africa and the only major producer in ...
USA
Copper is extracted from ore by crushing copper bearing ore followed by heap leaching with sulfuric acid and then moving the resulting solution to a tank containing scrap iron and agitating the solution to precipitate the copper. The tank possesses at least one gate for retaining the scrap iron, which gate is disposed above the bottom of the tank and has a mesh of at least one square inch.
