Copper is mainly extracted from copper pyrites After the concentration of its ore by froth flotation process the ore is roasted in a current of air to remove arsenic antimony and much of sulphur The ore is then mixed with a little coke and sand and smelted in a waterjacketed blast furnace
removal of iron in e traction of copper Ore Facts for Kids . The basic extraction of ore deposits follows these steps Prospecting or exploration to find and then define the extent and value of ore where it is located (ore body) Conduct resource estimation to mathematically estimate the size and grade of the deposit Conduct a prefeasibility study to determine the theoretical economics of the
#0183;#32;Copper smelter slag and copper smelter slag flotation tailings were leached using sulphuric acid solutions, without or with the addition of either ferric sulphate or hydrogen peroxide. Copper extraction from the slag was typically found to be twice as high as that from the slag flotation tailings. Hydrogen peroxide was determined to be the best lixiviant.
It is estimated that per tonne of copper tonnes of slag is produced from copper smelters. Currently copper slag is mainly applied as a building material (as a replacement of sand or concrete aggregate), or is being dumped. Copper concentrations in copper slag from smelters vary

Copper slag is +2a form of olivine, a magnesium, iron and silicate mineral with the formula (Mg, Fe+2) 2 SiO 4. The production of nano silica from the dissolution of olivine is an economic option when compared with the traditional commercial method which requires high temperature vapourization of
Copper extraction refers to the methods used to obtain copper from its ores. The conversion of copper consists of a series of physical and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors. As in all mining operations, the ore must usually be beneficiated. The processing techniques depend on the nature of
of slag/pyrite/copper concentrate and the effect of the added iron powder to leaching on the metals dissolution were investigated. Under optimum conditions, % of copper and % of cobalt were extracted in roasting at high temperatures in a closed medium 3:6:6 of slag/pyrite/copper concentrate rate then roasting at 600 #176;C at 5 hours.
Copper Mining and Extraction Sulfide Ores. The ore from the mine contains about 2% copper. To get at the copper the first stage is crushing in huge cylindrical ball mills. Ball mills crush the ore into a fine powder. (Courtesy of Rio Tinto.)

Copper slag, or fayalite slag, is a byproduct obtained during the matte smelting, converting and refining of copper (Fig. ). 54,59 It has been estimated that for every tonne of copper produced, about tonnes of slag is generated, 60 as a consequence of the relatively low grades of copper
Copper extraction from the slag was typically found to be twice as high as that from the slag flotation tailings. Hydrogen peroxide was determined to be the best lixiviant. Thus, copper and iron extractions were % and %, respectively, when leaching the slag with 3 M H. 2.

Copper slag is a byproduct yielded from a copper refinery. The annual amount of copper slag in Japan is two million tons. The copper slag has been used for cement material, sand blasting
Copper slag is a byproduct of copper extraction by smelting, impurities become slag which floats on the molten metal. Slag that is quenched in water produces angular granules which are disposed of as waste or utilized as discussed below.
