Request PDF Chloride as an alternative to cyanide for the extraction of gold Going full circle At the present time cyanide is the most widely used reagent to extract gold from its ores andFurther Details
The PLATSOL process originally designed to recover the platinum group metals PGM’s from their ores and concentrates provides an alternative to cyanide for gold ores The process generates oxidizing conditions in the autoclave capable of forming the Au ion and gold chlorocomplexes result from the addition of small quantities 510 gL of sodium chloride to the autoclaveFurther Details
Jan 01 2016 · Oxidative chloride sulfide and ammonialeaching processes are generally more applicable for the extraction of gold or platinum group metals as a byproduct from base metal sulfide concentrates Despite the research interest and pilot plant trials on many of the noncyanide gold lixiviants the majority are still at the development stageFurther Details
Oct 10 2019 · The oxidation agent was observed to affect gold extraction In a slightly more concentrated chloride solution 28 M gold extraction was 93–94 when minor cupric 01 M and 002 M was used as oxidation agent In ferric leaching the gold extraction was slightly lower 85–89 with ferric concentration of 01 M and 004 MFurther Details
Oct 12 2015 · Dundee Sustainable Technologies DST is ratcheting up its efforts to create a cyanidefree gold extraction process In early July the company commissioned an industrialscale demonstration plant in Thetford Mines Quebec capable of processing up to 15 tonnes per day of gold concentrate using its proprietary chlorination processFurther Details
Abstract Despite of being the most common hydrometallurgical process for extraction of gold from ores and concentrates cyanide leaching is blamed for its hazardous impact on environment and human health These concerns have given a rise for alternative cyanidefree technologies such as cupric chloride leachingFurther Details
