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

The process involves the separation of hydrophobic from hydrophyllic minerals. Flotation has now become the most widely used process for extracting minerals from ores. Designing flotation schemes in a laboratory allows you to optimize the process. Minerals require coating with a chemical to make their surface hydrophobic.

How silver is made - material, making, history, used ...

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.
