Possibility of sodium cyanide elimination from a flotation process . Ahmad K. CDarban. 1. Abstract: In base metals concentration using flotation technique, pyrite decreases the quality of metal concentrates and increases the amount of sulfur compounds. To avoid low efficiency, depression of pyrite (FeS2) is essential. Flotation tests were conducted using four mixed collector systems (Aero238 ...

Ingredients: sodium oxide, nitrogen, ammonium, calcium, iron, etc. Usage: while being used, the noncyanide gold extraction reagent must be agitated with alkaline water at normal temperature, and then dissolved in a slurry to do gold the process of heap leaching, pool leaching and CIP production of oxidized gold ore, the process is as same as the process of ...
Kinetics of natural degradation of cyanide from gold mill ...
After zinc addition, gold is precipitated from a goldcyanide complex. Waste streams from the process generally contain a sufficiently high concentration of cyanide and heavy metals that treatment is essential. The oldest treatment method practiced by Canadian gold mines for cyanide destruction is "natural degradation".

Cyanide Use in Gold Mining
A sodium cyanide solution is commonly used to leach gold from ore. There are two types of leaching: Heap leaching: In the open, cyanide solution is sprayed over huge heaps of crushed ore spread atop giant collection pads. The cyanide dissolves the gold from the ore into the solution as it trickles through the heap. The pad collects the now metalimpregnated solution which is stripped of gold ...
