Matte metallurgy Britannica

Matte, crude mixture of molten sulfides formed as an intermediate product of the smelting of sulfide ores of metals, especially copper, nickel, and lead.Instead of being smelted directly to metal, copper ores are usually smelted to matte, preferably containing 40–45 percent copper along with iron and sulfur, which is then treated by converting in a Bessemer-type converter.

The Gold Smelting Process Melting, Smelting &

Refining Gold . Smelting is not always the final stage in gold extraction. Depending on the intended use of the gold, it may have to be refined before being put to use. Refining gold is simply the process of removing the finer impurities that the smelting process could not remove. There are several methods used to refine gold.

Smelting and refining Glossary Sumitomo Metal

Smelting and refining. Refining processes extract valuable metals from ores or other raw materials. They fall into two basic types: pyrometallurgical (dry) and hydrometallurgical (wet). At SMM’s Toyo facilities in Ehime Prefecture, the copper concentrate pre-processing undertaken at Saijo uses pyrometallurgical processes and the nickel

How to Make Flux for Gold Refining Our Pastimes

Refining gold from ore or concentrates is done during the smelting process. During this process, flux is used to dissolve contaminates such as metal oxides from the gold. The flux is added to a crucible with the gold that is then melted in a furnace. You can make flux for gold refining by first obtaining all of the

Copper Smelting an overview ScienceDirect Topics

W.G. Davenport, in Encyclopedia of Materials: Science and Technology, 2001 4 The Future. The major trend in copper smelting and converting is towards improved capture of the SO 2 that is evolved from oxidizing CuFeS 2 and other copper sulfide minerals. Improved SO 2 capture benefits the environment and the resulting H 2 SO 4 product can be used for leaching “oxide” and supergene sulfide
