Sulfide Smelting - Physical Chemistry of Metallurgical ...

Smelting happens to be one of the main steps in the extraction of metals from sulfide and oxide minerals by adopting the pyrometallurgical route. During smelting, constituents present in the charge in molten state separate into two immiscible liquid layers, namely, liquid matte or metal and liquid slag.

Development of Recyclable Iron Sulfide/Selenide ...

Fast and effective removal of elemental mercury in a wide temperature range is critical for the smelting industry. In this work, a recyclable magnetic iron sulfide/selenide sorbent is developed to capture and recover Hg0 from smelting flue gas. Benefiting from Se doping, the Hg0 capture performance of prepared FeSxSey is significantly enhanced compared with traditional iron sulfide, especially ...

12.3 Primary Copper Smelting

In the smelting process, either hot calcine from the roaster or raw unroasted concentrate is melted with siliceous flux in a smelting furnace to produce copper matte. The required heat comes from partial oxidation of the sulfide charge and from burning external fuel. Most of the iron and 10/86 (Reformatted 1/95) Metallurgical Industry 12.3-1

Smelting - Wikipedia

Smelting is a process of applying heat to ore in order to extract a base metal. It is a form of extractive metallurgy.It is used to extract many metals from their ores, including silver, iron, copper, and other base metals.Smelting uses heat and a chemical reducing agent to decompose the ore, driving off other elements as gases or slag and leaving the metal base behind.

Antimony Smelting - 911metallurgist

Mar 19, 2017  The history of the antimony industry of China dates back to 1897 when the Tai Shing Co. was formed, under contract with the Hunan Bureau of Mines, for the smelting of the ore to crude; and in 1908 the Wah Chang Mining Smelting Co. was formed for the smelting and refining of the ore and crude to regulus.

US3849120A - Smelting of copper-iron or nickel-iron ...

The smelting of Cu-Fe-S or Ni-Fe-S ore concentrates is initiated by heating to between 1,200*C and 1,300*C to produce Cu2S and FeS, as well as S2, through a mixture of fuel, steam and oxidizing gas, such as 50 to 95% O2. The introduction of steam converts FeS to FeO and produces H2S, while the introduction of O2 converts FeS to FeO and produces SO2.

Smelting and Roasting Ores to recover gold, silver and ...

The product of melted sulfides is called a matte, and is highly corrosive liquid. Converting that molten sulfide matte to metal is called smelting. Small scale smelting can be done in a crucible – in fact that is what a fire assay is. When smelting assays are done on high sulfide ores, a couple of iron nails are added to the mix.

Impacts of Smelting - Base Metal Smelting

Smelting is known to be a major cause of pollution in the environment. When smelting occurs, along with the metal produced, a solid waste product, called stag, is also produced [1]. This slag is emitted into the air and can be a cause of the pollution although not a major one. The majority of the pollution is caused by air emissions [1].
