Effect of grinding parameters on the rheology of pyrite

Jun 01, 2007 As the cracks and defects of pyrite reduce when the particles decrease to micron dimension, it is difficult for pyrite to comminute on wet ultra-fine grinding. Another possible reason is that special surface area and surface energy increase simultaneously, which leads to the agglomeration of particles and the observable increase of viscosity.

Extracting gold from pyrite roster cinder by ultra-fine

Mar 01, 2003 高达10%返现 The ultra-fine-grinding and resin-in-pulp with pH value of 10 are used to extract gold from pyrite roster cinder. During leaching process, aluminium oxide ball is used as stirring medium, hydrogen peroxide as leaching agent and sodium hexametaphosphate as grinding agent. With AM-2σ resin as absorber and sulfocarbamide as eluent, gold is recovered from cyanide pulp of pyrite

(PDF) EFFECT OF ULTRAFINE-GRINDING ON CYANIDE LEACHING

Ultra-fine grinding of the concentrate (i.e. d80 from 80 µm to 4.2 µm) further improved leaching of gold and silver i.e. up to 83% Au and 70% Ag even at 1.5 g/L NaCN. Under suitable conditions i

Interfacial and optical characteristics of pyrite

Based on these results, pyrite ultrafine powder was prepared using sodium dodecyl sulfate and sodium oleate as grinding additives, whose optical characteristics were studied by FTIR spectrometry

Development of ultrafine grinding at Kalgoorlie

Nov 01, 2003 高达10%返现 In February 2001, Kalgoorlie Consolidated Gold Mines (KDXN) commissioned its first full-scale ultrafine grinding (UFG) plant to supplement its existing roaster-concentrate treatment capacity. The process involves the fine grinding of refractory pyritic concentrate to 10 μm followed by direct cyanide leaching for gold recovery. By this means, gold can be economically

Roasting Vs Ultrafine Grinding Of Pyrite
