In the case of the higher energy consumer, the pregnant liquor is pumped five miles from the leach site to the sx/ew plant. the electrowinning of copper requires considerably more electrical energy than does the electrorefining process - an average of about 8 mj/kg for electrowinning vs.
Jan 01, 2016 however, gold leach in the studied grinding circuit at lab scale caused an increase in cyanide consumption with a higher generation of iron cyanide and scn-. these results were confirmed by tests in the canadian malartic plant where the cyanide addition was moved from the sag mill to the leaching tanks resulting in a 20% savings in cyanide.
Jun 18, 2014 ultrafine grinding (ufg) was proposed as a pretreatment method prior to cyanide leaching of old plant tailings of a refractory silver ore. direct cyanidation of the as-received tailings (d 80: 100 m) led to a low silver extraction of only ≤43% over 24 h.a size-based diagnostic study has demonstrated that the refractoriness of the tailings is essentially physical in.
Leaching is a physico-chemical process where minerals in rock masses go through dissolution under percolating water and anion/cation exchange reactions to generate metal salts in solute/colloid phase that migrate and accumulate under hydrological.
