Ferrochromium Alloys Manufacturing
To produce low-carbon stainless steels, an iron charge together with HCFeCr and sometimes charge chrome or blocking chrome are processed in the Argon-Oxygen Decarburizer (AOD). Chromium recovery in the production of HCFeCr by submerged arc smelting ranges from 85 to 90 percent, but in the AOD it is greater than 98 percent.
Fire Assay Procedure
FIRE ASSAY EQUIPMENT. Fire assay procedures use a combination of intense heat (1900 °F) that is produced by a furnace, dry reagents called fluxes, and bone ash containers called crucibles and cupels. One uses this combination to fuse the fluxing agents and to isolate the precious metals. The ability to fire assay a substance relies on …

Guidelines on flux calculation gold smelting
Goldroom smelting practice indicates that pyrometallurgy might even be impossible if the gold concentration is too low. This is in contrast to Barcza (1985) who reports that methods of phase concentration of gold by pyrometallurgy which can provide 99.5% recovery from feedstock containing 20 parts per million gold have been developed.

Dewatering Equipment
Concentrate Thickening & Filtration The concentrate (or concentrates) produced in the facility must usually be dewatered prior to shipment. The first step of the dewatering procedure is usually sedimentation. The design engineer must be extremely careful when developing the size of concentrate thickeners from laboratory data. In the laboratory, …
Designing Smelting Furnaces to Meet Process Requirements
The furnace components must be designed to function together to avoid plastic deformation, erosion, corrosion, and fracture. Thermal cycling, intense heat loads, and required design loads are not typically found in design handbooks or codes. The loads can vary significantly as the refractory lining wears.

Ferrochrome Smelting In Zimbabwe
Ferrochrome smelting is a labour and energy intensive process. The principal application for chromium is as an alloying element in cast irons and steels. It is a strong carbide-forming element, and as such it is an important alloying element in tool and die steels, and high speed steels. Zimbabwe currently has the capacity to produce about 490K ...

Flash Smelting Furnace
Flash Smelting Furnace. Flash smelting (Finnish: Liekkisulatus, literally "flame-smelting") is a smelting process for sulfur-containing ores including chalcopyrite.The process was developed by Outokumpu in Finland and first applied at the Harjavalta plant in 1949 for smelting copper ore. It has also been adapted for nickel and lead production.
