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 - CuFeS 2. From the formula, it is clear that iron and sulphur have to be removed in order to produce copper.
Iron ore is converted into various types of iron through several processes. The most common process is the use of a blast furnace to produce pig iron which is about 92-94% iron and 3-5% carbon with smaller amounts of other elements.
The mining industry has argued that submarine tailings disposal (STD), which disposes of tailings in the sea, is ideal because it avoids the risks of tailings ponds; although the practice is illegal in the United States and Canada, it is used in the developing world.
Chemical contaminants are chemicals toxic to plants and animals in waterways. The phrase 'chemical contamination' is used to indicate situations where chemicals are either present where they shouldn't be, or are at higher concentrations than they would naturally have occurred.
Other types of chemicals used include depressants, which form a polar chemical envelope around particles and depress the effect of any hydrophobic gangue minerals in the ore that would otherwise report with the froth along with the desired metallic mineral particles.

Additionally, today's mining equipment makes it possible to reduce waste and decrease chemical exposure during all phases of the copper mining process. The Basics of Copper Mining and Processing ...
Tailings characteristics can vary greatly and are dependent on the ore mineralogy together with the physical and chemical processes used to extract the economic product. Ritcey (1989) reported that tailings of the same type may possess different mineralogy and therefore will have different physical and chemical characteristics.
