  • Extraction of gold using cyanide NZQA

    Extraction Of Gold Using Cyanide Nzqa

    Extraction of gold using cyanide Gold is found in very low concentrations in the ore from which it is mined. To collect the gold from the ore it needs to be separated from the other minerals in the ore. To do this the gold needs to be made into a soluble form so that it can be separated from the other minerals as gold is insoluble.

    The Application Of Ecofriendly Gold Extraction Agent

    Mar 29, 2019 The commonly used gold extraction agents are NaCN, KCN, NH4CN, CaCN2. A major disadvantage of cyanide gold extraction is that cyanide is highly toxic, pollutes the environment and is slow to immerse gold. It is easily affected by impurities such as copper, iron, lead, zinc and arsenic. Therefore, the recovery rate is usually low.
