Introduction and use of slag pot - EB Castworld

2.Principle of use. The slag pots is mainly used to carry converter steel slag, refining furnace steel slag, and continuous casting bale casting. Under the conditions of the converter smelting process, the temperature of the steel slag is higher than. The temperature of the molten steel (because the steel slag is located in the high temperature region of the oxygen blowing reaction).

Leaching of copper and zinc from copper converter slag ...

It may therefore be concluded that due to pronounced dissolution of silicates acidic treatment of converter slag flotation tailings should not be used prior to chemical leaching. Comparison of the processes carried out at initial Fe 3 + concentrations of 5.3 and 15.7 g/L showed more efficient copper recovery in the latter case.

Environmental Guidelines for Copper Smelting

furnace is charged to converters where the molten material is oxidized in the presence of air to remove the iron and sulfur impurities (as converter slag) and to form blister copper. Blister copper is further refined as either fire-refined copper or anode copper (99.5% pure copper), which is used in subsequent electrolytic refining.

How to Recover Copper from Slag by Flotation

Possibilities for minimizing copper losses in converter slags include: (1) settling the molten slag to recover entrained matte and copper, (2) smelting the slag with a suitable reductant to recover a copper-iron alloy or a low-grade matte. (3) beneficiation of slags by magnetic separation, and. (4) treatment of the slag by flotation.

Converting (metallurgy) - Wikipedia

Converting is a type of metallurgical smelting that includes several processes; the most commercially important form is the treatment of molten metal sulfides to produce crude metal and slag, as in the case of copper and nickel converting. A now-uncommon form is batch treatment of pig iron to produce steel by the Bessemer process. The vessel used was called the Bessemer converter.
