mineral processing process of silver ores

Silver processing Britannica

2020-8-14  Silver-bearing ores are mined by open-pit or underground methods and then are crushed and ground. Since virtually all the ores are sulfides, they are amenable to flotation separation, by which a 30- to 40-fold concentration of mineral values is usually achieved. Of the three major types of mineralization, lead concentrates contain the most silver and zinc concentrates the least.

Processing of high-silver gold ores - ScienceDirect

2005-1-1  Gold and silver occur together in the alloy electrum that has no fixed composition, although the term is frequently applied to minerals with more than 20% silver. This chapter deals with ores, where the silver grade is sufficiently high to warrant modification to the design of the plant relative to that, which would be specified if the silver component was not present, and where the silver and gold are

A Study on Process Mineralogy and Mineral

The ores with a high oxidation rate contains arsenic and stibium, and the mosaic size of silver minerals in it is quite fine. The Study shows, the process of "pre - leaching by lead nitrate then all - sliming cyeddation" is suitable, and the recoveries of silver and gold reach respectively 83. 5% and 77. 5%.

Processing of High-Silver Gold Ores - ScienceDirect

2016-1-1  The most convenient processing alternative for high-silver gold ores and concentrates is largely dependent on the quantity and mineralogy of the silver phases present. As far as leaching is concerned, pretreatment of the ore or modification of the leaching chemistry may be necessary to remove or diminish the negative effects of stable precipitating anions.

Hard Rock Mining Gold and Silver Ore and processing it

2012-4-18  In most gold ores, the final process to extract the tiniest gold particles is the use of cyanide to dissolve the gold. Cyanide, in the presence of oxygen actually dissolves both gold and silver. It is both efficient and inexpensive, so it is widely used in precious metal ore processing.

ores and oxidized ores are free-milling and gold can be recovered by gravity and/or direct cyanide leaching. Some epithermal deposits may be free-milling (such as the oxidized portion) but more commonly contain significant amounts of sulfides in which gold occurs as tiny inclusions or submicroscopic gold and are therefore refractory.
