Bioleaching - SlideShare

Feb. 02, 2017. 32,150 views. "Bioleaching" or "bio-oxidation" employs the use of naturally occurring bacteria, harmless to both humans and the environment, to extract of metals from their ores. Conversion of insoluble metal sulfides into water-soluble metal sulfates. It is mainly used to recover certain metals from sulfide ores.

Industrial practice of a distinct bioleaching system ...

As a result, acid and iron might be accumulated in the leaching solution system during the bioleaching process, (Table 3, Table 4) and leaching temperature may increase. With regard to the secondary copper sulfide (digenite and chalcocite), the leaching process in acid and iron solutions could be divided into two stages.

A Review on Potash Recovery from Different Rock and ...

The bioleaching extraction path consumes very high reaction time. However, in acid leaching, the process requires different mineral acids and a comparatively low reaction time than the bioleaching process. The roast leaching process is the best option as the roasting time is less and roasting additives are cheaper.

The gangue minerals include quartz, dickite, alunite mainly, and minor amounts of sericite and feldspar. The matrix of gangue minerals in the ore body is dominantly quartz (about 70%) because almost all the feldspar grains in the granite host rock were replaced by clay minerals and secondary quartz during hydrothermal alteration process.Fig. 3

advantages and disadvantages of mining industry

Some advantages of bioleaching include: Bioleaching can stabilise sulphate toxins from the mine without causing harm to the environment. Poisonous sulfur dioxide emissions harm the environment and can cause health problems for miners, and bioleaching avoids this process entirely.
