ABSTRACT A gold recovery pretreatment process is disclosed in which the gold content is more completely extracted from refractory sulfidic ores which contain large quantities of metal carbonates such as dolomite than occurs in traditional gold extraction methods. The process includes treating the ore in an autoclave at elevated temperature and oxygen overpressure conditions in the presence of ...
Bioleaching is an extractive technology that uses a solution inoculated with microorganisms to leach trace elements from polluted soils. It is also a process that is used in the mining industry as an alternative to cyanide to extract metals from lowgrade ores or mine wastes (Liu et al., 2007).

· Results are presented for a study of the pyrometallurgical treatment of goldarsenic concentrates with lead osmiumrheniumcontaining slags. Conditions are found for preparing alloy ingots consisting of lead, or predominantly of lead sulfide, or both phases. It is shown that with gravitation deposition up to 65–68% osmium is concentrated in 17–25% matte. Gold is almost uniformly ...

Tropical Journal of Pharmaceutical Research is an Open Access (OA) Journal. Open Access stands for unrestricted access and unrestricted reuse. With Open Access, researchers can read and build on the findings of others without restriction. Much scientific and medical research is paid for with public funds.
Reprocessing this material using bioleaching technologies has the potential to recover valuable metals, while reducing the toxicity, reactivity, and acid generating potential of the remaining residues. CanmetMINING is currently developing a stirredtank bioleaching process to recovery nickel and cobalt from pyrrhotiterich tailings.
Thus, DWW treatment by bacteria is found to be a feasible process. The operating conditions and treatment efficiency of a variety of bacterial processes is given in Table The removal of COD and BOD is found to be effective (>75%) at a pH of around 7. The temperature of the processes ranges from 30°C (mesophilic) to 60°C (thermophilic).
