4 Extraction Processes for Gold-Pyrite Ore

The Extraction Processes of Gold-Pyrite Ore The treatment principle of gold-pyrite ore is to separate the sulfide from the gangue and dissolve the gold in the cyanide solution. In order to remove antimony, arsenic, carbon and other substances that absorb fluoride, roasting treatment is required before cyanidation. There're 4 extraction processes.

How Pyrite Is Mined And Processed

Iron pyrite is a fairly common mineral, and is mined or extracted globally for its many industrial uses, such as extraction of the sulphur for sulphur dioxide or sulphuric acid, and also as an ore for iron. It oxidises readily, making it easy to extract the component minerals, but care must be taken as this also makes it quite combustible.

Pyrite Mineral Uses and Properties

Pyrite Framboid: One of the most interesting crystal habits of pyrite is the "framboid." These tiny spheres of euhedral pyrite crystals are often found in organic muds, coal, shale, and other types of rocks. This is a framboid from the Waynesburg coal of northern West Virginia. It is a sphere about 15 microns in diameter that is composed of cubic crystals of pyrite about one micron on
