Silver is commonly extracted from ore by smelting or chemical leaching. Silver mining is the resource extraction of silver by mining. Silver ore beneficiation first choice is large capacity magnetic separation, followed by is electrostatic separation, and then re-election, and the minimum is flotation.

 

Silver involved in mixing silver ore, salt, copper sulphide, and water. A method called the cyanide, or heap leach, this process has gained acceptance within the mining industry because it is a low-cost way of processing lower-grade silver ores.

 

1. Broken or crushed (by jaw crusher, cone crusher or impact crusher, and ball mill) silver ore is stacked on impermeable pads to eliminate the loss of the silver cyanide solution. Pad material may be asphalt, plastic, rubber

 

2. Silver ore is crushed into pieces, usually with 1-1.5 in (2.5-3.75 cm) diameters, to make the material porous. Approximately 3-5 lb (1.4-2.3 kg) of lime per ton of silver ore is added to create an alkaline environment.
