Recovery of metal values from copper smelter slags by ...

Pyritic Smelting a process for treating massive pyritic kies that are composed of pyrite (FeS2) in association with some amount of chalcopyrite (CuFeS2). The theory of pyritic smelting was developed in the late 1920's by A. A. Baikov and V. Ia. Mostovich. Pyritic smelting is carried out in a shaft furnace; the coke consumption ranges from 2 to 4 ...

Red iron(III) oxide (Fe 2 O 3, commonly known as rust) is the most common iron oxide used in thermite. Magnetite also works. Other oxides are occasionally used, such as MnO 2 in manganese thermite, Cr 2 O 3 in chromium thermite, quartz in silicon thermite, or copper(II) oxide in copper thermite, but only for specialized purposes. All of these examples use aluminium as the reactive metal.

Most olivine is used in metallurgical processes as a slag conditioner. High-magnesium olivine (forsterite) is added to blast furnaces to remove impurities from steel and to form a slag. Olivine has also been used as a refractory material. It is used to make refractory brick and used as a casting sand.

The shape of the slag might be explained by the fact that the deposit plate tipped to one side in the tests, with the slag apparently running that way. Another indication of the low viscosity of the slag was the absence of discrete particles on the top of the slag. As discussed above, such particles were observed on top of the 'pyrite' slag.

Pyrite (FeS 2) is the most common sulfide mineral in coal and a major source of the sulfur in coal.Pyrite can form in peat while the peat is accumulating, or can form in peats from the introduction of sulfate (SO 4) into the peat if the peat was buried by marine waters (such pyrite is called syngenetic or authigenic pyrite).Within the buried peat, the sulfate is reduced to sulfide (S 2), which ...

The recovery of copper and cobalt from ancient copper slags from the Küre region of Turkey was investigated. A fayalitic-type of ancient copper slag containing 1.24% Cu, 0.53% Co and 53.16% Fe were subjected to an experimental study. Two different routes were followed to recover the metal values. The first route was roasting the slag with pyrite followed by leaching.

Jun 29, 2017· Ferrous slag is currently underutilized. Although the construction industry does use some slag as an aggregate, most is simply discarded. However, slag could be used to treat acid soils or acid mine drainage. Doing so would both offset the cost of restoring abandoned mine areas, as well as decrease steel manufacturers' current waste footprint.
