injected into the converter via a lance submerged in the slag. Converter matte is tapped and bottom cast into moulds, slow-cooled, crushed, and despatched to the refineries. Slag is granulated and dried for recycling to the slag-cleaning furnace. ACP slag is fed to the slag-cleaning furnace along with a reductant and a sulphur source.
These rates can be characterized for this plant during slag granulation operations, but it should be noted that slag granulation operations take place only intermittently throughout the year. Waste Water from Electrolytic Cells Electrolytic cells are used to refine anode copper into high purity cathode copper.
Rasa system in slag granulation Products. As a leading global manufacturer of crushing, grinding and mining equipments, we offer advanced, reasonable solutions for any size-reduction requirements including, Rasa system in slag granulation, quarry, aggregate, and different kinds of minerals.
Slag granulation using water sprays is now an established technology that not only simplifies blast furnace casting floor operations but also provides an economical route for producing of a valuable raw material for a host of industries. The slag granulation plant comprises three sections: for granulation, dewatering and storage.
The slag was generated from BCL Outokumpu flash furnace during the refining and smelting of their concentrate. Slag formation varies depending on the way it is cooled, and BCL copper slag was cooled rapidly (using the water granulation process). As the slag has undergone rapid cooling, it has irregular small shapes of 1–4mm with black ...
