When formulating a cyanidation system for silver-containing ore, the following measures should be taken: 1) Leach with concentrated cyanide solution (0.2~0.6% NaCN); 2) Long time (up to 2 to 3 days) leaching; 3) Inflate strongly into the pulp; 4) Add lead salt to the pulp; 5) Bromine cyanidation and so on.Web

First of all is the room where the ore is being ground into powder. This is necessary before the smelting and wasting processes begin. Here and there are heaps of powdered ore, each pile marked with the name of the mine from which it has been taken. This ore is gray or brown or red in color and looks like any common powdered stone.Web

Ore, scrap silver, or Doré bar (lower purity silver often produced on-site at the mine) is melted in a crucible. A dip sample is taken from it to measure the purity of its silver content. The steps after that may be determined by the impurities present in the silver, and these processes may be repeated as needed.Web
