  • Gold cyanidation Wikipedia

    Gold cyanidation (also known as the cyanide process or the MacArthurForrest process) is a hydrometallurgical technique for extracting gold from lowgrade ore by converting the gold to a watersoluble coordination complexIt is the most commonly used leaching process for gold extraction Production of reagents for mineral processing to recover gold, copper, zinc and silver represents· In the cyanidation process, lime can be used as a depharmaceutic agent for the gold concentrate cyanide plant before the immersion thickener to remove harmful substances, prevent the occurrence of gold concentrate runoff phenomenon and reduce unnecessary losses; As a prealkali dipping agent, it is used to eliminate the unfavorable factors of the leaching reaction before leaching; itLime in Gold Ore Mining Process | Flotation, CyanidationWhat are the dangers of using cyanide? Cyanide is highly toxic, and can result in substantial environmental impacts and public health risks if released into the environment Cyanide spills have resulted in major fish kills, contaminated drinking water supplies and harmed agricultural lands For example: Mexico, 2014: 500,000 gallons of cyanide solution spilled from a retaining pond at theCyanide Use in Gold Mining Earthworks
