Bioleaching of Copper from Electronic Waste Using Aspergillus Niger and Acidithiobacillus
The main concern of this study is to establish a feasible and an economical method of extracting copper from electronic waste using Aspergillus Niger and Acidithiobacillus Thioxidans. Both Aspergillus Niger and Acidithiobacillus Thioxidans are known to exhibit efficient generation of organic acid and sulfuric acid respectively. To establish their leaching potential, chemical leaching tests usin...
متن کاملBioleaching of zinc and nickel from silicates using Aspergillus niger cultures
In this work, we investigated the role of bacteria from the genera Bacillus and Pseudomonas and fungi from the genera Ž . Aspergillus and Penicillium in the leaching process of two different silicates calamine and garnierite . Since the results obtained with A. niger were better than those with different bacteria, a more detailed investigation of the leaching process with this microorganism was...
متن کاملUse of Aspergillus niger in the bioleaching of colemanite for the production of boric acid
Colemanite is one of the most important underground riches of Turkey, having approximately 60% of the world boron deposits, and it has a large portion in the deposits. In this study, chemical leaching and biological leaching methods were used for production of boric acid from colemanite (2CaO · 3B3O3 · 5H2O) (Emet-Kütahya, Turkey). Oxalic acid concentration, temperature, stirring time and solid...
متن کاملBioleaching of Low Grade Manganese Ore with Penicillium citrinum
A native microorganism, Penicillium citrinum was isolated from the top soil of a manganese mine. Based on its efficiency for manganese solubilisation, it was utilized for the leaching of a low-grade manganese ore. The effects of various parameters such as pulp density, particle size, sucrose concentration, inoculum size and bioleaching duration on manganese ore were studied. The optimised condi...
متن کاملOptimization of parameters affecting recovery of copper from Sarcheshmeh low-grade sulfide ore using Bioleaching
In this work, the parameters affecting the recovery of copper from the low-grade sulfide minerals of Sarcheshmeh Copper Mine were studied. A low-grade sulfide ore was used with a copper grade of 0.25%, which was about 28% of the mineral oxide, and the sulfide minerals made up the rest. Much more sulfide minerals were found to be pyrite and most of the gangue minerals were quartz, anorthite, bio...
