Mineral Resources Malaysian Minerals

2021-8-2  Gold: Gold production in 2016 decreased substantially by 52.5 per cent to 2,249 kgs from 4,732 kgs in 2015. The output came from 12 gold mines located in Pahang, Terengganu and Kelantan. Malaysia’s major gold producers are the Selinsing Gold Mine and the Penjom Gold Mine both located in Kuala Lipis, Pahang.

Optimization Process of the Refractory Gold Ore Extraction

2021-1-8  The gold ore samples were obtained from Selinsing Gold Mine in Peninsular, Malaysia. The samples were pre-treated by crushing and grinding below 75 μm in particle size. The ground samples were later blended homogeneously before the experiments.

Extraction of Gold

The ore is reduced to a fine state of division and amalgamated simultaneously in a stamp-mill, the solid gold-amalgam separated from the liquid mercury by filtration through leather under pressure, and the mercury distilled. Complete extraction of the gold by amalgamation is impossible, a part remaining in the mud of the stamp- mills.

Sodium Cyanide Orica

Gold Extraction Process. 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 industry.
