silver milling method


Extraction Method of Silver in Gold-Silver Ore #1 Gravity Separation Method Silver can be enriched by gravity separation, but its enrichment degree is much lower than that of gold. It is usually processed by a jig to collect coarse (greater than 0.1~0.2 mm) heavy minerals, namely natural silver, argyrite and hornsilite.

As soon as the ore is freed from the base chlorides soluble in water, a solution of hyposulphite of lime (70) is led in from a tub or tank, on the ore, in order to dissolve the chloride of silver. This leaching is conducted like the former. It depends on the amount of silver how long this work continues—from eight to twenty hours.

Ball milling is a mechanical technique that is broadly used to grind powders into fine particles [134-141]. The reactants are generally broken apart using solvent molecules in the traditional method; but in ball milling, reactants are broken by using mechanical forces. The term mechanochemistry has been introduced very recently [142].

Because both lead and silver were solu­ bilized, silver recovery from high-silver ore would be difficult. Similar methods were used by Scheiner (8-10) to extract silver and other metals-from a complex sulfide concentrate. These methods re­ quired a C1 2-02 or FeC12-02 leach at ele­ vated pressure and temperature to form

Basically gold and silver leaching involves spraying a cyanide solution on the ore to dissolve the metal values, collecting the solution containing the dissolved metals, and recovering the metal from the solution. By eliminating milling, leaching reduces capital cost and startup time for new operations.
