2019-5-9 MacArthur developed the cyanide process for gold extraction in 1887. The solution of sodium argento. cyanide combines with zinc dust and forms sodium tetra cyanozincate and precipitated silver. This precipitated silver is called spongy silver. Zn+2Na[Ag(CN)2]Na2[Zn(CN)4]+2A g The spongy silver is fused with potassium nitrate to obtain pure silver.

2015-8-24 Issues of gold extraction using cyanide: Cyanide is toxic to animal and plant life and may cause death if exposed to high enough doses. Free cyanide is cyanide ion (CN-) and hydrogen cyanide (HCN) which is often gaseous as it is volatile. Free cyanide causes cellular asphyxiation. The process: The ore is ground and crushed to make a slurry
