Effects of pyrite and sphalerite on population

Furthermore, the additions of pyrite or sphalerite both made the increase of redox potential (ORP) and the concentrations of Fe3+ and H+, which would affect the microbial community compositions and copper extraction efficiency. Additionally, pyrite could enhance copper extraction efficiency (e.g., improving around 13.2% on day 6) during diergetos194.jpg" />[]

For extraction of gold from the refractory ores in which gold is surrounded by sul-fide minerals, oxidative pretreatment of the ore is essential to oxidize the sulfides and expose gold. Pyrometallurgical oxidation by roasting is encountered with environmen-tal limitations; thus hydrometallurgical methods are preferred. These methods includediergetos109.jpg" />
