Cyanide is especially developed for that mining of silver and gold: It can help dissolve these metals making it possible for separation from the other solids. In the cyanide procedure, finely floor substantial-grade ore is blended with the cyanide (at a ratio of about 1:five hundred parts NaCN to ore); very low-grade ores are stacked into heaps and sprayed with a cyanide solution (at a ratio of about 1:1000 parts NaCN to ore).
