Silver, for example, often occurs in the compound argentite (silver sulfide) or in lead compounds. Historically, the key chemical processes included amalgamation with mercury and leaching in a solution of chlorine, sodium or calcium hyposulfite (lixiviation), .
In this process, ore was heated with rock salt, producing silver chloride, which was leached out with sodium hyposulfite. Today, there are several processes used to extract silver from ores. A method called the cyanide, or heap leach, process has gained acceptance within the mining industry because it is a lowcost way of processing lowergrade silver ores.
