Minerals | Free Full-Text | Effects of Pyrite Texture on ...

Pyrite particles, having framboidal/altered texture, are known to significantly affect pulp chemistry and adversely affect flotation performance. Therefore, the main objectives of this study were to demonstrate influence of pyrite mineralogy on the flotation of copper (sulphidic) ores and develop alternative conditions to improve the performance.

Pyrite - an overview | ScienceDirect Topics

The nucleation of pyrite in sediments requires extreme supersaturations. The supersaturation limit, Ω*, is the supersaturation level up to which a phase can be expected not to precipitate spontaneously and is a measure of minimum nutrient concentrations where nucleation is relatively fast and not rate-limiting.The supersaturation limit for pyrite, Ω pyrite *, in the presence of pyrite seeds ...

Pyrite: The mineral pyrite information and pictures

Pyrite was once used as a source of sulfur, but is now only a minor ore for both sulfur and iron. Pyrite from some localities is auriferous, and therefore is used as an ore of gold in gold-bearing localities.Pyrite was polished by the Native Americans in the early times and used as mirrors. Today, it is used as an ornamental stone, as well as a very popular stone for amateur collectors.
