Silver processing, preparation of the ore for use in various products.. Silver has long been valued for its white metallic lustre, its ability to be readily worked, and its resistance to the corrosive effects of moisture and oxygen.The lustre of the pure metal is due to its electron configuration, which results in its reflecting all electromagnetic radiation of wavelengths longer than 3000
Description: Process which uses microorganisms for the recovery of precious metals from metal-containing processes and streams. This technology is targeted at using naturally-occurring, sulfate-reducing bacteria for the recovery of gold and silver from ores, instead of the more traditional -- and more toxic -- cyanidation process

silver mining process instruction. How Silver Is Made Material Making History Used .mining and processing the silver bearing ores are mined by either open-pit or underground mining methods after which they are crushed and ground. despite of the existence of other technologies, this metal is mined through a process that uses gravity to break and extract its ores from large deposits. this
At this point, the Silver mine is ready to begin extraction. Most often, the ore is removed starting at the bottom and working up one layer at a time in a method called overhand stoping. Mines include a network of tunnels and chambers designed to safely raise the pulverized ore up and out in mine cars
