UFG of pyrite concentrates for subsequent leaching is used in ores, where refractoriness to direct cyanidation arises from fine to ultrafine (<20, >0.02 μm) gold mineral inclusions in the pyrite and/or arsenopyrite.By grinding to 80% passing 10 mm a significant fraction of
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.
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
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
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
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
Jun 26, 2020 Roasting Vs Ultrafine Grinding Of Pyrite. Physical encapsulation can be overcome by ultrafine grinding however this is often not economically viable if the gold is encapsulated in sulfides oxidation of the sulfide minerals by roasting pressure oxidation
ies obtained with sample of pyrite ore after ultrafine grinding (IsaMill) as a method of liberating the physically locked gold. The cyanidation of a refractory pyritic gold ore (4.95 g/t gold,
Harbort et al. (1998) reported the results of improvements in gold recoveries obtained with sample of pyrite ore after ultrafine grinding (IsaMill) as a method of liberating the physically locked
This laboratory work presents a study of the effect of ultrafine grinding on the gold recovery of a highly refractory gold concentrate. The particle size of the concentrate was P80 = 46 pm and the
