List Sulphide Minerals

The sulphide minerals are compounds of the metals with sulphur. Nearly all these minerals have a metallic luster, i.e., the peculiar shining appearance of metals, such as gold, silver, copper, lead, tin, iron, etc. They are all heavy minerals and nearly all are of economic importance. Iron Pyrites or Pyrite

Lecture 5: Sulphide minerals and acid rock drainage

When sulphide minerals oxidize metal ions will be released into solution. Additionally, some sulphide minerals will release hydrogen ions (H +) during the process which lowers the pH of the water. Acid and metal rich water originating from oxidation of sulphide minerals is called acid rock drainage (ARD).

Polymetallic massive sulphide deposits

Sediment plumes created by mining operations may impact suspension feeders, such as sponges and corals. In addition, the pulverisation of massive sulphides on the ocean floor will produce highly reactive sulphide mineral surfaces, generate acid by-products and potentially release harmful major and trace metals into the environment.

As in all mining operations, the ore must usually be beneficiated (concentrated). The processing techniques depend on the nature of the ore. If the ore is primarily sulfide copper minerals (such as chalcopyrite), the ore is crushed and ground to liberate the valuable minerals from the waste ('gangue') minerals.

Effective flotation collector reagent selection is dependent on the sulphide minerals present, their mineral associations in the ore, and circuit characteristics. Because an ore typically has more than one copper sulphide mineral type, often a combination of sulphide flotation collectors is used to maximize metallurgical performance.
