Silver processing Britannica

Silver-bearing ore was ground and then mixed with salt, roasted copper ore, and mercury. The mixing was accomplished by tethering mules to a central post on a paved patio (hence the name of the process) and compelling them to walk in a circle through the mixture. The silver was gradually converted to the elemental state in a very finely divided form, from which it was dissolved by the mercury.

Silver mining - Wikipedia

Once silver ore has been removed from a mine, it is crushed into a fine powder. Silver is commonly extracted from the powdered ore by smelting or chemical leaching. Silver's melting point occurs at 962 o C (1764 o F, 1,235.15K). As such, industrial metallurgic processes are needed to prepare silver for commercial purposes.

Hard Rock Mining Gold and Silver Ore and processing it

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. The carbon method requires an additional step where the metals are removed from the carbon. The result of both methods is a finely divided black metal powder of

Silver element extraction methods – Open pit, underground ...

The ore containing silver needs to be refined to obtain pure silver as an end product. The silver precipitate obtained previously may contain some impurities and so the impure silver is purified by the electrolytic method. The process requires a block of impure metal to be the anode while a thin strip of pure silver is fetched as cathode. A mixture of silver nitrate solution is taken as the electrolyte. On passing current through the electrolytic tank, the impure silver

Extraction Of Silver - Mineral Processing Metallurgy

10/01/2017  The extraction of silver by the solving processes simple. The ore is first roasted with salt in the usual way, whereby the formation of base metal chlorides cannot be avoided entirely. After roasting, the ore is first subjected to leaching with water, in order to extract the base metal chlorides, and then with hyposulphite of lime, to extract the silver.

Ore processing is a 24 hour operation. Ore is stockpiled (1) at the processing plant, and the process begins by feeding the ore into a hopper with a loader. The ore is conveyed, and lime is added (2) to raise the pH of the ore. Following crushing through a jaw crusher (3), the ore is fed into the semi autogenous grinding (SAG) mill (4) along with water and steel balls. The grinding process reduces the rock to a
