This is another article in my series on the smelting of metals, this one focusing on the smelting of copper. 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 .

Gold Smelting Process | Sciencing

The first step in the gold smelting process occurs when ore containing gold is mined from the earth. At this point, the crude binding matter and the gold metal need to be separated. This is accomplished by pulverizing or crushing the gold ore, and then placing it in a furnace.

US5180422A - Copper smelting process - Google Patents

A copper smelting process is disclosed in which copper concentrate is smelted in a furnace to produce purified copper. Flue gas discharged from the furnace is treated to produce sulfuric acid. Furthermore, waste liquid discharged during the production of sulfuric acid is treated to produce gypsum, and the gypsum thus produced is recycled to the furnace as a flux.

Copper Smelting Chemistry Tutorial - AUS-e-TUTE

The earliest evidence of copper smelting occurs in Serbian artefacts dating from around 5000 BC. Copper can be extracted from oxide ores using electrolysis (electrowinning) for low grade ores, or by the carbon reduction method of smelting for higher grade ores. The process of extracting copper from higher grade sulfide ores involves:

Continuous Copper Converting - Smelting | Home

This two stage smelting and converting process is being considered for installation at a number of copper smelter sites. The process is very easy to operate and is autogenous with combustion air enriched to approximately 30% oxygen. Solid feed combined with the high level of oxygen enrichment produces a low volume of offgas, rich in SO2.

What Is Copper Smelting? (with pictures) - wisegeek

Aug 10, 2019 · Copper smelting is the process of separating copper metal from the rock in which it is naturally embedded by melting it. This is accomplished through a series of several processing steps. The term copper smelting may refer to this melting step in particular or it may refer somewhat less formally to the entire process overall.
