Deportment of toxic trace elements in the CIP/CIL cyanidation process
Abstract
The deportment of a suite of elements through representative gold ore processing unit operations has been investigated.Chromium and lead are not soluble in alkaline cyanide solutions.Arsenic, antimony, cobalt, molybdenum, selenium, tellurium and vanadium are soluble, but typically do not adsorb onto activated carbon to any appreciable extent.Silver, copper, cadmium, mercury, nickel and zinc to varying extents report along with the gold to the carbon eluate.Cadmium, mercury and zinc can report to the carbon regeneration kiln off-gases.Strontium is soluble and adsorbs on carbon where it remains.
