1 Use an ammonium thiosulfate solution which is recycled at a temperature of 15-25°C to process silver-gold ore. 2 The filtrate produced after dissolution is electrolytically extracted with a high alloy electrode at a current density of 200...250 A/m 2 until the electrolyte reaches a concentration of 5-15 ppm Au, 1-100 ppm Ag and 0.1-1.0 g/1 Cu.

Silver is found in a native form very rarely as nuggets in placer deposits and veins. It is more commonly combined with sulfur, arsenic, antimony, or chlorine and in various ores such as argentite (Ag 2 S), chlorargyrite ("horn silver," AgCl), and galena (a lead ore often containing significant amounts of silver).

Silver can also be found as a byproduct of mining lead, zinc and copper. Nearly half of silver mined today is extracted when processing other kinds of ore.
The processes for extracting the silver, lead and zinc from the ore involve grinding, sequential flotation and leaching techniques that produce high-grade, marketable lead and zinc concentrates with a high silver content. The ore treatment process at Cannington uses primary underground and surface crushing.

As one can see, silver production costs go well beyond the mere act of pulling the metal from the ground. This is why we have different notions of silver production costs. Traditionally, the industry used cash cost, which focused only on the mining and processing costs incurred.

Production of Silver across the Ancient World Paul CRADDOCK* Dept. of Conservation and Science, The British Museum, London WC1B 3DG. (Received on November 30, 2013; accepted on March 3, 2014) The quest for silver through antiquity encouraged a succession of major developments across a variety of technologies.
Copper ore beneficiation methods. Before the beneficiation of copper ores, crushing and grinding are required. The bulk ores are crushed to about 12cm by a jaw crusher or a cone crusher. Then the crushed materials are sent to the grinding equipment, and the final particle size of the copper ore is reduced to 0.15-0.2mm.

Copper and silver are not the only ore processing products. Gold, nickel, lead, selenium, rhenium and platinum metals are recovered from domestic copper ores. According to information provided by KGHM Polska Miedź, 431 kg of gold, 29,000 tonnes of lead, 3,000 tonnes of nickel sulphate, 87 tonnes of selenium and 137 kg of Pt-Pd concentrate were produced in 2015.

1. Discussion of Typical Production Processes Most domestic gold comes from surface lode mines. Silver is mined using open pit and underground methods. Several processes may be used to recover gold and silver from their ores. These include gravity separation, amalgamation, froth flotation, and cyanidation.

Production of bullion-grade silver is, however, seldom achieved. As in the production of silver powder for electronic applications, metallic silver can also be reduced directly from solution using a reducing agent such as hydrazine, but in the presence of large amounts of base metals, the selectivity of this process is poor.

Today, silver metal is primarily produced instead as a secondary byproduct of electrolytic refining of copper, lead, and zinc, and by application of the Parkes process on lead bullion from ore that also contains silver. In such processes, silver follows the non-ferrous metal in question through its concentration and smelting, and is later
