Sanbrado gold project is a highgrade mining project being developed in the southeastern region of Ouagadougou in Burkina Faso The gold project is being developed by West African Resources 90 and Government of Burkina Faso which holds a 10 freecarried interest With an estimated preproduction capital cost of 186m the project is expected to produce 301000oz of gold in the firstGet Price
In heap leach operations the oxidant is usually the air present in the heap In any cyanidation process it is crucial to have both cyanide and an oxidant in the conditions prevalent in most cyanide plants the rate of gold extraction is controlled by the dissolved oxygen content of the pulpGet Price
Further LeachAid allows anaerobic dissolution of gold and thus allows the Consep Acacia to use heated leaching for even faster kinetics and more complete leaching In 2011 an independent study conducted in Perth Australia compared the Consep Acacia to a rival product operating in a gravity gold circuitGet Price
Chemical Leaching Chemical leaching makes use of the chemical properties of gold to leach it from ore concentrate or tailings This process is mostly used in large scale mining operations but has been increasingly adopted in small scale mining because of its high gold recovery rate and low costGet Price
