smelting silver ore process

Smelting - Simple English Wikipedia, the free encyclopedia

Smelting is the general term for getting a metal from its natural ore.Gold is an exception because it is usually found as a pure metal. Other metals, like iron, copper, zinc, and silver, need to be got from their ore.. The process of smelting always involves heating the ore, and may also use a reducing agent like coke or charcoal.Most ores are oxides, sulfides or carbonates.

We shall begin by looking at the mining and processing of the copper bearing ore, followed by an examination of an established and a modern copper smelting process. Mining for Copper Bearing Ore. There are two categories of copper ore; sulphide ore which is processed to enrich it before smelting, and oxide ore that is subjected to acid treatment.

Silver mining - Wikipedia

Silver is commonly extracted from ore by smelting or chemical leaching. Ore treatment by mercury amalgamation, such as in the patio process or pan amalgamation was widely used through the 1800s, but is seldom used today.. Silver is also produced during the electrolytic refining of copper and by application of the Parkes process on lead metal obtained from lead ores that contain small amounts ...

12.3 Primary Copper Smelting

A typical pyrometallurgical copper smelting process, as illustrated in Figure 12.3-1, includes 4 steps: roasting, smelting, concentrating, and fire refining. Ore concentration is roasted to reduce impurities, including sulfur, antimony, arsenic, and lead. The roasted product, calcine, serves as a dried and heated charge for the smelting furnace.

Silver processing | Britannica

A process routinely employed in the fire assaying of gold ores is the addition of silver prior to fusion of the ore in order to ensure that the silver content of the final bead is high enough to dissolve. This is called inquartation, and the separating of silver and gold by leaching with nitric acid is referred to as parting.
