Feeder System Redesign for Flash Furnace at BHP Copper
Feeder System Redesign for Flash Furnace at BHP Copper BHP Copper - San Manuel, Arizona The Need Demands for increased production from existing flash smelting furnaces have led to increased concentrate burner feed rates and the use of more finely ground concentrates. Unfortunately, feeding finer materials at higher rates increases the likelihood of erratic flow or even flooding from the furnace charge bin, usually located above the furnace. The safe and efficient operation of any flash smelting furnace depends on a continuous, non-pulsating feed of dry charge mix, at an accurately controlled rate. BHP Copper operated a 3,400 tons per day dry concentrate, single burner, Outokumpu flash smelting furnace at its San Manuel copper smelter in Arizona. The Initial Problem The first six months o
