Sep 30 2021 Some concentrators will use a sand separation process to achieve the extraction of copper from sulfide ore. After the ore is ground and classified the mud and sand are flotated separately. Most of the gangue enters the fine mud part and becomes waste tailings in the flotation process. The flotation of the sludge and the finely ground

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

A copper ore is a mixture of copper minerals and other materials in the rock called gangue from which it is economically viable to extract the metal. A typical copper ore contains between 0.5 and 2.0 copper. A high grade ore produces a high yield of metal. A low grade order produces a low yield of metal.

The ore is processed by froth flotation comprising rougher and scavenger cells. The common reagents for copper ore flotation are xanthates as collector pine oil as frother sodium cyanide as depressant and lime to maintain slurry alkalinity. The concentrate in the form of froth and slurry contains 20 copper.

Jan 17 2022 The steps depend on the type of ore the reactivity of the metal and the nature of impurities present in the ore. These processes involved in the extraction and refining of the metal are called metallurgy. The ores of most of the metals should be brought to the Earth’s surface for extracting metal from them. This process is called mining.
