How Is Gold Extracted From Gold Ore? | Sciencing

Several processes can then be used to separate the gold from the ore. The most common techniques in the United States use cyanide in various ways. In one, the ground ore is put into a tank containing a weak cyanide solution and zinc is added. The zinc causes a chemical reaction which separates the gold from the ore.

Silver chloride - Wikipedia

Silver chloride is a chemical compound with the chemical formula Ag Cl.This white crystalline solid is well known for its low solubility in water (this behavior being reminiscent of the chlorides of Tl + and Pb 2+).Upon illumination or heating, silver chloride converts to silver (and chlorine), which is signaled by grey to black or purplish coloration to some samples.
