differences in biomining and bioleaching

Bioleaching genomics - Europe PMC Article - Europe PubMed

Alternatively, bioleaching (or biomining) by microorganisms is used to extract metals from ores by dissolving them into extremely acidic aqueous solution. Bioleaching is a natural process involving acidophilic bacteria and archaea, which have the ability to either oxidize metal sulfides or to oxidize reduced inorganic sulfur compounds (RISCs

Biomining: metal recovery from ores with microorganisms

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.

Thermophilic microorganisms in biomining | SpringerLink

Abstract. Biomining is an applied biotechnology for mineral processing and metal extraction from ores and concentrates. This alternative technology for recovering metals involves the hydrometallurgical processes known as bioleaching and biooxidation where the metal is directly solubilized or released from the matrix for further solubilization, respectively.

Comparison of Heterotrophic Bioleaching and Ammonium

The term bioleaching is applied to biomining techniques where the target metal is solubilized by the action of microorganisms or by products of microbial metabolism. Bioleaching has been tested on various rocks and waste material to mobilize REE (summarized by ). The majority of these studies used heterotrophic microorganisms and report highly

Comparison of Three Approaches for Bioleaching of Rare Earth

Approximately 300 million tonnes of bauxite are processed annually, primarily to extract alumina, and can contain moderate rare earth element (REE) concentrations, which are critical to a green energy future. Three bioleaching techniques (organic acid, reductive and oxidative) were tested on three karst bauxites using either Aspergillus sp. (organic acid bioleaching) or Acidithiobacillus

Frontiers | Quantitative Monitoring of Microbial Species

Monitoring of the microbial community in bioleaching processes is essential in order to control process parameters and enhance the leaching efficiency. Suitable methods are, however, limited as they are usually not adapted to bioleaching samples and often no taxon-specific assays are available in the literature for these types of consortia. Therefore, our study focused on the development of

Bioleaching is a technique in biomining, which uses microorganisms to solubilise your metal(s) of interest [1]. Therefore, you can see that the difference lies in what happens to your metal(s) of interest. If your metal of interest is to be dissolved in solution by microorganisms, then the correct term to use is ‘bioleaching’.
