Removal of cyanide from the gold cyanidation plant

· The adsorption experiments on the tailings of a gold cyanidation plant showed that the developed adsorbents were capable of removing more than 90% of cyanide from the real sample Introduction Cyanide compounds are extensively used in a number of applications including mineral processing, photographic, electroplating, steel and iron, plastic, jewellery and chemical industries

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

Recovering Cyanide From Gold Plant Tailings

The ability to recover cyanide from gold plant tailings has been known almost as long as the cyanidation process has been practiced, but there has been little incentive to process tailings in this way in the past With the development of technologies that make it possible to recover and recycle free or complexed cyanide directly from gold plant slurry tailings, which indicates, on paper at
