How To Used Sodium Cynide For Gold Tailings

An example of cyanide trough leaching for gold

The mixed mercury tailings are classified by hydraulic classification box and separated into grain-grade rocker to obtain lead concentrate containing 50% lead and gold 11.6g/t. The shaker tailings are abandoned by coarse sand sedimentation tank and fine sand sedimentation. The grain size of coarse ore sand obtained by sedimentation is 98%-0.42mm, and that of fine ore sand is 98%-0.125mm. The

Is cyanide safe to use in mining? – Szilvia Malik

30.11.2018· Cyanide – in the form of sodium cyanide – is mostly used in gold and silver mining. Since gold and silver are both soluble in cyanide, sodium cyanide can be pumped into a mine, as part of a leaching process to extract these precious metals from ore. Proponents of the cyanide process argue it is quite safe, as long as the cyanide-laced substance returned to the surface is stored safely in

The process design of gold leaching and carbon-in-pulp

gold plants use conventional thickening with flocculant addition. High rate thickeners, as well as de-watering systems that use cyclones only or cyclones and high-rate thickeners can also be used in principle. Leaching reagents in the form of cyanide and an oxidant such as air or oxygen are added after thickening. Leaching takes place in a series of agitated leach reactors or pachucas. Before

Processing, smelting and refining gold | World

For extracting gold from low-grade ores, heap leaching is practiced; huge heaps are sprayed with a dilute solution of sodium cyanide, and this percolates down through the piled ore, dissolving the gold. There are very well defined rules for the safe and responsible use of cyanide – as laid out in the International Cyanide Code. Gold refining
