Biomining: metal recovery from ores with

Biomining is an increasingly applied biotechnological procedure for processing of ores in the mining industry (biohydrometallurgy). Nowadays the production of copper from low-grade ores is the most important industrial application and a significant part of world copper production already originates from heap or dump/stockpile bioleaching.

Enhancement in copper extraction from chalcopyrite

2015-7-1  Consistent with the diverse changes in copper extraction, the effects of different strategies of re-inoculation at mid-stage on the population dynamics were complex and classified into two main groups : re-inoculation group with sulfur-oxidising bacteria (‘Ac-M1/3’) and re-inoculation group with iron-oxidising microorganisms (‘Ft-M1/3’ and ‘L.f-M1/3’).

Metals Extraction from Sulfide Ores with

Encouraging results have been achieved by using microbial consortia, because consortia has great potential to withstand against arsenic, copper, and chloride ion , prevent iron contamination of leach liquor during manganese extraction and desirable for downstream processing of metal recovery , and hold barotolerant (higher pressure resistant) ability that can contribute in anaerobic iron and sulfur cycling

Methods of Metal Recovery by Microorganisms (2

2021-7-1  In fact, microorganisms can be successfully used for the extraction of metals (e.g., copper, zinc, cobalt, lead, uranium) from low grade ores. Mining with microbes is both economical and environmental friendly. The term metal is used to any substance that is hard, possessing silvery lusture, and is a good conductor of heat and electricity.

Detection and analysis of attached microorganisms on

2011-2-1  Moderate thermophiles were used to bioleach pure chalcopyrite and showed good performance of copper extraction in the stirred tank reactor. The attached microorganisms on the mineral surface were detected by atomic force microscope (AFM). The result showed that the attached cells could produce extracellular polymeric substances (EPS) rapidly.

Copper processing - Ores Britannica

Extraction and refining. The extraction of copper from ore is normally carried out in three major steps. The first step, mineral processing, is to liberate the copper minerals and remove waste constituents—such as alumina, limestone, pyrite, and silica—so that the copper minerals and other nonferrous minerals of value are concentrated into a product containing between 20 and 30 percent copper.
