The Resiliency of the Philippine Small-Scale Mining Communities ...

Since the start of the community quarantine, there was a nationwide lack of supply of chemicals such as cyanide which led to limited gold processing, especially in the town of Buenavista where there's only one gold processing plant. The next closest processing plants are situated in Bicol, a four- to five-hour ride away.

Cyanide Use in Gold Mining - Earthworks

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 metal-impregnated solution which is stripped of gold and resprayed on the heap until the ore is depleted.

Cyanide Leaching Of Gold - Mine Engineer.Com

Since the 1890's, cyanide has been used to recover gold from gold bearing ores. And today, over 115 years later, most of the worlds gold is recovered with cyanide playing a large part in the beneficiation of the yellow precious metal. Chemically, it is a rather simple reaction: 4 Au + 8 (NaCN) +O2 + 2 H2O = 4 NaAu (CN)2 + 4 NaOH
