concentrate dryer flash smelt

Jul 03, 2017 · The Smelter recently “reset” the asset health of critical, larger equipment such as installation of a new FSF (with new burner and air-slide systems) and a new gas-fired concentrate dryer. The innovative FSF design (which included elimination of roof refractory brick) will further enable processing of ‘hotter’ and lower grade feed at sustained higher throughput rates

overcoming inefficiencies in flash smelting process

Aug 09, 2018 · Potential areas for improvement within flash smelting. The gradual or rapid change in concentrate composition and feed blends can adversely affect furnace operation. These inefficiencies in flash smelting operations are occurring more often now that primary feedstocks are steadily being depleted. One strategy being implemented to offset these changes is the blending of high and low …

the copper flash cc smelting process :: total materia article

Chemically, concentrates smelted in flash furnaces contain 20-30 mass % Cu, 25-35% Fe and 25-35% S. The process takes place in a flash smelting furnace, which schematically is presented in Figure 1. Main feedstock of the process is a dry Cu-Fe-S concentrate. Very roughly speaking, dry concentrate is blasted with O 2 in the reaction shaft. The furnace is equipped with hydrocarbon fuel burners located …
