COPPER-PYRITES, or Chalcopyrite, a copper iron sulphide ( C u F e S 2 ), a crucial ore of copper. Chalcopyrite crystallizes within the tetragonal system with inclined hemihedrism, but the shape is so nearly cubic that it has not been recognized as tetragonal. From the above explanation option (c) i.e.

copper transportation from a source region, but the protore does not need to have high copper content if leaching and precipitation are efficient. Conversely, the second type requires substantial protolith copper content if the copper oxide zone developed is to be of potential ore grade, and requires also that removal of copper be minimal.

Sphalerite is depressed with zinc sulphate addition to the grind with sodium sulphide as an option for enhancing pyrite depression. Copper is floated in the first differential flotation stage at a 10-11 pH with lime. Xanthate, dithiophosphate and thionocarbamate collectors are used as explained much more extensively in the copper flotation section.

Hence, the extraction of copper from its pyrite ore is difficult than from its oxide ore through reduction. What is the process of extracting copper? Copper mining is usually performed using open-pit mining, in which a series of stepped benches are dug deeper and deeper into the earth over time. To remove the ore, boring machinery is used to

The tailings and the waste rock at most mines are an environmental liability because they both contain pyrite plus small amounts of ore minerals. When pyrite is exposed to oxygen and water it generates sulphuric acid—also known as acid rock drainage (ARD). Acidity itself is a problem to the environment, but because the ore elements, for example copper or lead, are more soluble
