Therefore, in the flash smelt technology only little fossil fuel addition is needed. In the settling area of the furnace, the matte and slag forming reactions take place.

  • Copper Smelting and Refining Process Pan Pacific

    The copper concentrates are fed through the flash smelting furnace with oxygen-enriched air. 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.

  • Overcoming inefficiencies in flash smelting Process

    2018-8-9 · 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-quality ores, often of greatly varying compositions. Additionally, some smelters buy concentrate from a variety of sources andKiln vs flash calciner Fruitful,The kiln system provides the gradual heating and extended retention time (normally ~30 minutes) needed to effect the conversion on large particles.
