Copper Mining and Extraction Sulfide Ores

At this stage of the process, the chemical reactions begin. They convert the copper minerals into copper metal. We can illustrate the types of process using the example of chalcopyrite CuFeS2. From the formula, it is clear that iron and sulfur have to be removed in order to produce copper. The roasting process: changes.

raised about this type of mining. Pyrite (FeS2) is exposed to air (O2) and water (H2O). A sequence of reactions occur creating sulfate, ferric hydroxide and hydrogen ions. Additional chemical reactions occur involving pyrite, iron sulfate and water, resulting in the release of sulfuric acid. Sulfuric acid promotes release of other.

Gold cyanidation Wikipedia

Gold cyanidation is a hydrometallurgical technique for extracting gold from low grade ore by converting the gold to a water soluble coordination complex. It is the most commonly used leaching process for gold extraction. Production of reagents for mineral processing to recover gold, copper, zinc and silver represents.

Oscillating Chemical Reactions Inside Mines

Oscillating reactions are among the most fascinating of chemical reactions. In one type of reaction, a mixture of chemicals goes through a sequence of color changes, and this sequence repeats periodically. In another, the mixture periodically emits a burst of gas, foaming up. To many, oscillating reactions are engaging.

This includes the mining of coal, copper, gold, silver, zinc, lead, and uranium. The mineral pyrite, more commonly known as "fool's gold," is iron disulfide (FeS2). Pyrite is one of the most important sulfides found in the waste rock of mines. When exposed to water and oxygen, it can react to form sulfuric acid (H2SO4).
