cyanidation in mineral processing

  • Cyanidation Metallurgist & Mineral Processing Engineer

    The gold cyanidation process is the most important method ever developed for extracting gold from its ores The reasons the widespread acceptance of cyanidation are economic as well as metallurgical It usually obtains a higher recovery of gold than plate amalgamation and is easier to operate than the chlorine or bromine processA common Cyanidation Process for Gold or called CIL and CIP The amount of these two reagents in the slurry is very important, without enough cyanide to consume all of the valuable mineralGold Cyanidation Process Mineral Processing & Metallurgy(1990) Gold Cyanidation Plants in China Mineral Processing and Extractive Metallurgy Review: Vol 6, No 14, pp 217228Gold Cyanidation Plants in China: Mineral Processing and
