by neutralizing the acid leach liquor or by leaching oxide copper with ammonia but neither solution was economical. a molecule that extracted copper well from typical dump leach liquors pH 1.8 had to be built. The reagent LIX 64 containing the ketoxime LIX Copper recovery using leachsolvent extractionelectrowinning technology
the leach liquor to reject impurities and precipitation of high-purity gold powder. This paper outlines the process presents selected results of two pilot-plant trials in which 5 kgd of high-purity gold was produced from silver-refining anode slime and gold-electrowinning cathode sludge and provides some details of the cost benefits.
To optimize the recovery and separation process of nickel and vanadium from the sulfate leach liquor the influence of different D2EHPA to Cyanex 272 ratios various temperatures such as 25 40 and 60 C and two different diluents including kerosene and carbon tetrachloride were studied.
Engineering. Chemical Engineering. Chemical Engineering questions and answers. Question 3 A pilot plant is set up to treat copper leach liquor by solvent extraction prior to electrowinning. The copper leach liquor containing 1gL of Cu2 3gL Fe3 at pH 2.2 is subjected to countercurrent solvent extraction using LIX 64 dissolved in kerosene.
Product liquor from this stage is the principal lixiviant in the other low acid stage although additional spent may be directed to the low-acid leach to maintain the overall plant balance. In the cocurrent process the first-stage low acid leach is run under similar conditions as the first-stage leach in the countercurrent flow sheet.

Dec 01 2020 Ilmenite FeTiO 3 concentrate was decomposed using 70 wt. potassium hydroxide solution at 220 C and under air at atmospheric conditions. The decomposed product was leached using hydrochloric acid solution and Ethylenediaminetetraacetic acid EDTA was applied for chelating and separating iron impurity from the leach solution.
