What is the role of silica in extraction of Cu from copper pyrite ore? Answer: Silica (SiO2) is used in the processes of smelting of copper pyrite

In the smelting process such chemical reactions are taking place: 1) oxidizing of the copper pyrite: 2 CuFeS2 (s) + 3 O2 (g) → 2 FeO (s) + 2 CuS (l) + 2 SO2 (g) 2) conversion of iron Get price

How Extraction of Copper from Copper Pyrites?

The copper pyrite is partly converted into sulphides of copper and iron. 2CuFeS 2 + O 2 → Cu 2 S + 2FeS + SO 2 2FeS + 3O 2 → 2FeO + 2SO 2 The Process in summary: The concentrated ore is heated stoutly with silicon dioxide (silica) and air or oxygen in a Get price

Rcovery of gold in pyritic ores

Geologists and mineralogists have many theories why and how the gold occurs with the pyrite, and I will not enter into any of these areas, since I am concerned with liberating the gold from the ores. I will say that from my understanding, many seem to agree that in sulfide gold ores, the occurrence of gold appears to occur as a replacement of other minerals, possibly iron. Get price

Common Iron Ore Extraction Processes

Usually, the polymetallic magnetic iron ore often contains cobalt silicate, carbonate minerals, pyrite, chalcopyrite and apatite. It is recommended to adopt weak magnetic separation - froth flotation process to the extraction of iron ore, namely recycling the iron by Get price

How to Separate Gold from Pyrite

So far no account has been taken of the loss of gold which is contained in pyrites, as it has been assumed that these are saved by concentration if they are valuable, and this subject is dealt with in earlier. Nevertheless, as this gold comes under the head of non-amalgamable gold, its physical state and the causes of its disinclination to unite with mercury may conveniently be considered here Get price

How Iron Pyrite is Formed

Metamorphic rocks are formed by heat and pressure, and pyrite could be formed as part of this process, or may form as a replacement mineral within the rock. In sedimentary rocks pyrite is usually found as a replacement mineral, when the iron and sulphur that is present in the sediments chemically combine to replace the original chemical composition of organic matter that is in the process of Get price
