In Direct Blister Flash Smelting the production chain is totally integrated. The process offers new options for different raw materials, thereby maximizing profit.
Today the Direct Blister Flash Smelting is the most profitable option for the lower grade concentrates too. The process is worth consideration for all concentrates containing more than 30% copper.
To ensure the economic feasibility of Direct Blister Flash Smelting process, all equipment is developed specially for high oxygen enrichment, and the furnace is specifically designed for blister copper production.
WMC has used Outotec's Direct Blister Flash Smelting process at their Olympic Dam smelter in Australia since 1988.
