Investigation of Flotation Parameters for Copper Recovery from Enargite and Chalcopyrite Mixed Ore
A flotation pre-treatment study for the separation of enargite (Cu3AsS4) from chalcopyrite (CuFeS2) ores of different origins was investigated in this work. The copper ore bearing enargite mineral contained 5.87mass% As and 16.50mass% Cu while the chalcopyrite bearing ore contained 0.32mass% As and 21.63mass% Cu. The two ore samples were mixed at 7 : 3 (enargite : chalcopyrite) by weight ratio ...
متن کاملBacterial consortium for copper extraction from sulphide ore consisting mainly of chalcopyrite
The mining industry is looking forward for bacterial consortia for economic extraction of copper from low-grade ores. The main objective was to determine an optimal bacterial consortium from several bacterial strains to obtain copper from the leach of chalcopyrite. The major native bacterial species involved in the bioleaching of sulphide ore (Acidithiobacillus ferrooxidans, Acidithiobacillus t...
متن کاملComparison of chalcopyrite bioleaching after different microbial enrichment in shake flasks.
The bioleachings of chalcopyrite ore were compared after inoculating different cultures enriched from the original acid mine drainage sample. The results showed that the higher bioleaching performance was achieved for inoculation with the enrichment D (0.5 % S, 2 % iron and 1 % chalcopyrite) compared to other enrichment systems. The generated ferric precipitation during bioleaching had a key in...
متن کاملStructural and Electronic Properties of Chalcopyrite Semiconductors
We have studied the structural and electronic properties of pure, deffect and doped chalcopyrite semiconductors using Density functional theory (DFT) based first principle technique within Tight binding Linear Muffin Tin orbital (TB-LMTO) method. Our calculated structural parameters such as lattice constant, anion displacement parameter(u) in case of pure chalcopyrite and anion displacement par...
متن کاملChalcopyrite Nanoparticles as a Sustainable Thermoelectric Material
In this report, copper iron sulfide nanoparticles with various composition were synthesized by a thermolysis based wet chemical method. These inherently sustainable nanoparticles were then fully characterized in terms of composition, structure, and morphology, as well as for suitability as a thermoelectric material. The merits of the material preparation include a straightforward bulk material ...
