The effect on copper leaching from chalcopyrite

Objective of this study was enhancement of sulfuric acid leaching of copper using ball milling. To accomplish this, optimum conditions of solid/liquid ratio of slurry, air volume in the mill, rotation speed and ball diameter were investigated for copper leaching from copper concentrate in which pyrite and chalcopyrite were dominant components

Recovery of rare earths from bauxite residue slag by high

2018-7-20 · High-pressure acid leaching (HPAL) can limit the dissolution of not only silicon, but also of titanium, aluminium and iron, as hydrolysis of the ions of these elements on, the material was ground in a ball mill to reduce the particle size to < 90 µm. Small iron particles in the slag sample were removed by a magnet after grinding.

Sequential bioreductionbioleaching and bioreduction

A novel hybrid process involving bioreduction and bio-/chemical leaching principles has been proposed for enhanced recovery of copper from concentrator plant ball mill unit waste. A dissimilatory metal reducing microbial consortium (DMRB) was seen to bioreduce Fe(III) phases with possible mineral matrix alteration in the reject sample.

Comparison of Cyanide and Chloride-Hypochlorite

In this research, cyanide and chloridehypochlorite leaching of gold from a pyritic concentrate (particle size: 75+53 µm, gold content: 27.15 g/t) were compared. It was shown that only 13.6 % of gold was extracted after 24 h leaching by cyanide, as compared to 37.2 % after 8 h by chloridehypochlorite. Effect of ultrafine milling of the concentrate on the leaching was investigated
