Copper-making by the pyrometallurgical process is based on extracting elemental copper (Cu°) from a multicomponent system of polymetallic sulphides in four steps: fusion, conversion, fire refining and electrolytic refining,, :. Fusion of the concentrates is a continuous oxidative process.

US5882620A Pyrometallurgical process for forming

A process for forming a salt, such as sodium tungstate, using a pyrometallurgical operation is provided. A slagging operation is performed in which a metal-containing material is melted in the presence of slag formers such as sodium metasilicate and silica. The metal predominantly reports to a denser metal-containing phase. The denser metal-containing phase may then be subjected to gas

Modeling of process by experimental design technique. In optimal conditions 99.2 ± 2.5% of phosphorus removal. The remaining phosphorus content is acceptable to produce ferrochromium alloys.

New Trends in Submerged Arc Furnace Technology

2010-1-5  FeCr production is carried out either in DC or AC based SAF. The increasing share of fine ores in the mine bodies of newly explored mines might force the ferro chrome producer either to agglomerate the ore or to process it directly as fines. A common way of charging fines to the SAF is via a hollow electrode system (HES), which had first been
