Revealing the multi-stage ore-forming history of a mineral …
The high-dimensional trace element data of pyrite can well record the history of ore formation, but this information is hard to be interpreted using traditional two-dimensional plots. Supervised machine learning provides a powerful tool to decode these data and discriminate ore genesis based on learning from labeled pyrite compositions.

Gold Leaching of Pyrite Concentrate
Gold Leaching of Pyrite Concentrate. The ore consisted of quartz, in which, above the 250-ft. level, the iron-minerals were largely oxidized and some free gold was visible; below that level few traces of oxidation occurred, and pyrite constituted the principal mineralizer in the quartz, together with occasional pockets of galena and a few …

Prediction of acid mine drainage: Where we are
The mining and ore processing of sulfide-bearing deposits generates large volumes of waste rock (WR) and tailings, which often contain barren and residual iron sulfides (e.g., pyrite and pyrrhotite). Sulfide oxidation under atmospheric conditions can generate acidic leachates loaded with high concentrations of dissolved metal( oid )s …

How to Recover Gold from Pyritic Ore
If it is with the pyrite straight cyanidation or flotation can do the job. If the gold is in the pyrite it is a different ballgame. There is a process of nano grinding the pyrite ore, usually a concentrate, in an attritior with a solution of sodium thiosulfate. I have been experimenting with this and have been getting in the high 90's recovery.
