Biomining is an increasingly applied biotechnological procedure for processing of ores in the mining industry (biohydrometallurgy). Nowadays the production of copper from lowgrade ores is the most important industrial application and a significan...
Apr 15, 2019· Bioleaching is a frontier technology promising for environmentfriendly treatment of slags. Therefore, the objective of this work was to study the feasibility of metal (Co, Mo, REE, V) bioleaching from copper metallurgical wastes employing Acidithiobacillus thiooxidans bacterial strain as the leaching agent. The effect of particle size (fractions < mm and – mm) and pulp density (1%, 2%) .

The possibility of using different groups of microorganisms for the recovery of valuable metals from a variety fraction of leadzinc waste was investigated. It is found that the bioleaching of zinclead wastes of valuable components depends not only on the species of microorganisms, but also on the fractional composition of the waste.
As a result, the mixed culture was The effect of nutrient medium on the ORP, copper concentration performed better at 32 8C for bioleaching of the copper dust. and extraction are shown in Fig. 7.
Bioleaching of oxide and silicate ores require heterotrophic microorganisms which are able to produce organic acids, mainly oxalic acid, citric acid, gluconic acid, tartaric acid, and pyruvic acid. Aspergillus and Penicillium are the most widely used important filamentous fungi for the extraction of metals from oxide ores [6, 7]. Metal leaching by
Oct 01, 2003· Eleven heterotrophic isolates from an alkaline slag dump, including nine bacteria strains, one fungus and one yeast isolate, were investigated for their ability to leach alkaline siliceous material. The efficiencies of these isolates were compared with those of chemical processes.

Bioleaching of the converter slag was studied on bench scale using Thiobacillus Ferroxidens, an iron oxidising bacteria for recovery of valuable metals at room temperature. Parameters such as particle size, pH, pulp density, Fe (II)/Fe(III) ratio and amount of Fe(II), additives etc., were optimised to treat the slag.
Aspergillus niger PSSG8 is assisted bioleaching of monazite to recover the constituent metals were investigated. Bioleaching was carried out using Bromfield (BM1/10P BMP) and sucrose media (SM1/10P SMP) with different levels of Phosphate under rotary and stationary conditions. The growth of the A. niger PSSG8 significantly reduced the media pH to acidic.

Stirred tank reactor (STR) leaching of nonferrous metals from copper smelting slag was conducted using biogenic Fe3+ solution containing H2SO4. The solution was initially obtained through biooxidation of FeS2+S° by using a moderately thermophilic microbial culture such as Sulfobacillus thermosulfidooxidans at 45°C and was applied as lixiviant in STR leaching experiments.

Bioprocessing for copper recovery from a lean grade chalcopyrite ore of Malanjkhand Copper Project (MCP) is reported. This ore with % copper, which is adjacent to the rich grade ore (% Cu), available in large amount is untouched for want of a suitable option, can be utilized to meet the growing demand of the metal in the country.
The bioleaching was carried out in 500 ml Erlenmeyer flask with 200 ml LB medium at % pulp density in pH 9 and shaking in an incubator shaker (200 rpm) at 30°C. The experiment featured two variables, copper removal with nitric acid and 2 leaching times, 1step and 2step bioleaching for enhanced cyanide production and gold dissolution.
Use of fungi and plants in biomining Fungal species are also being used for biomining. Many experiments have been conducted by using two fungal strains Aspergillus niger and Penicillium simplicissimum . These have the ability to assemble copper and tin up to 65% while zinc, lead and .
Bioleaching was then studied by culturing fungi on the MSW. Addition of Aspergillus niger correlated with an efficient removal of heavy metal elements. The effect of pH was also determined and assays at pH using a clay medium (%) or at pH using a sorghum medium (28%) were characterised by a .
scale, and recovery of several other metals is also possible using such methods . Some of the main areas of mineral biotechnology have been discussed in the present review. Microorganisms Widely Used In Mineral Processing Bioleaching using Autotrophs Autotrophs are considered to be the first biotic metabolism indicating the origin of life.
