    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,

    Hard Rock Mining Gold and Silver Ore and processing it

    In both methods, gold and silver is accumulated in the cyanide leach solution. The gold and silver bearing liquid, called pregnant solution, is separated from the ore by various drainage and filtration processes. The most common methods to remove the gold and silver involve activated carbon, or zinc precipitation.

    Silver Lead Zinc Ore Processing Method using Flotation

    It is necessary to recover as much silver as possible in the lead concentrate as a higher return for this silver is realized than for the silver in the zinc concentrate. The ore contained sphalerite, a portion of which was easily floatable but difficult to depress in the lead flotation circuit.

    Silver is rarely found alone, but mostly in ores which also contain lead, copper, gold, and other metals which may be commercially valuable. Silver emerges as a byproduct of processing these metals. To recover silver from zinc-bearing ores, the Parkes process is used. In this method, the ore is heated until it becomes molten.
