at Waterval Smelter in 2006 and the anticipated upgrade of Mortimer Smelter to 38MW in 2011. Several advances have been made in the smelting operations to improve the furnace stability and longevity. Control of the chromium input to each of the smelters has substantially allowed continued operations at levels below the spinel
1.2 Brief Process Description - Smelter Plant ISASMELT is an established novel pyro-metallurgical bath smelting process for the extraction of copper from copper concentrates. The process comprises of smelting the copper concentrate in a vertical cylindrical refractory brick lined flat roofed furnace vessel.
Zinc smelting is the process of converting zinc concentrates ores that contain zinc into pure zinc. Zinc smelting has historically been more difficult than the smelting of other metals e.g. iron because in contrast zinc has a low boiling point.
In the furnace the concentrates are instantly oxidized after which they melt and separate by their own reaction heat into copper matte with a grade of 65% and slag consisting of iron oxide silica and other compounds. Reaction in the flash smelting furnace. CuFeS 2 SiO 2 O 2 Cu 2 S・FeS 2FeO・SiO 2 SO 2 Reaction heat.
The general process flowsheet of the copper smelter used for piloting the COCOP solution is pre-sented in the figure 1. The main materials are sulfidic copper concentrates that are first blended to feed mixture and then dried before processing. Flash Smelting Furnace FSF and Peirce-Smith Converters PSC are in the heart of the operation.
Economic of Smelter Processing Smelter Costs The concentrate assay is the prime importance indetermining the valuation and the value of the assay isusually agreed on the result of independent sampling andassaying performed by the mine and smelter. The assays are compared and if the difference is no morethan an agreed value the mean of the two results may betaken as the agreed assay. In the ...

The precipitate obtained in the Merrill-Crowe process is very sensitive during the smelting process due to the process employ diatomaceous earth as a filtration medium. This material contains silica. Then it is important to know the silica content in the cement so that the fluxes can be added in the right proportion in order to avoid unexpected problems in the process.
