How is cyanide used in 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.
Although sodium cyanide is a commonly used reagent in mining, most mines do not have a dedicated cyanide safety expert onsite to assist with safe and efficient handling. The right sodium cyanide partner provides knowledge, training, resources, and onsite support to facilitate continuous operational improvement and innovation.

This processing plant is soaking the mineral grains which after fine milled with sodium cyanide (potassium) solution and make the precious metals into solution, then use zinc powder for revivification precipitation, or with other methods get the metal from the solution. It’s an important method to extracted gold silver and other precious metals from the ore.
Some gold mining plants have been applied, and the effect is good. 3. Advantages of CNFREE. CNFREE eco-friendly gold leaching reagent is a kind of leaching reagent that can replace sodium cyanide without changing the original equipment and cyanide process. It can be used directly for gold ore beneficiation and refining.
The product strength is quoted on a molar basis as either sodium or calcium cyanide. The form of cyanide reagent chosen for use typically depends on availability, distance from the source and cost. Where liquid cyanide is used, it is transported to the mine by tanker truck or rail car and is off-loaded into a storage tank. The truck or rail car may have a single or double walled tank, and the
Sod ium cyanide has been used in the extraction of gold from ore for over a century. Today it is still considered the most efficient extraction method with sodium cyanide used in the leaching process in most gold mining operations. Orica is one of the largest producers of sodium cyanide for the mining
Sodium cyanide is a poisonous compound with the formula NaCN. It is a white, water-soluble solid. Cyanide has a high affinity for metals, which leads to the high toxicity of this salt. Its main application, in gold mining, also exploits its high reactivity toward metals. It is a moderately strong base. When treated with acid, it forms the toxic gas hydrogen cyanide: NaCN + H2SO4 → HCN + NaHSO4
Mar 07, 2016· According to the ICMC, the amount of cyanide used in commercial gold operations is typically in the range of 0.01% and 0.05% cyanide (100 to 500 parts per million), and the code’s website states that no accidental human deaths due to cyanide poisoning have been documented by the Australian and North American mining industries for over 100 years.

Results of the cyanide destruction investigations conducted on the CIL tails with the sulfite process are presented graphically in Figure 1 and Figure 2. Both pulp and solution detox investigations were conducted with sodium metabisulfite (SMBS) used as the reactant with the pH maintained at 9 by controlled NaOH addition.
Commissioned in 1988, the plant was the first of its kind in Australia. It was established to service the growing gold mining industry in Western Australia where sodium cyanide is used for the extraction of gold. Since this time, the plant has been upgraded and is now capable of producing up to 78,000 tonnes of liquid sodium cyanide per annum.
