Copper Ore Rhenium

Rhenium is recovered during pyrometallurgical processing of molybdenum sulfide and copper sulfide ores the traditional technology involves removing rheniumvii oxide, re 2 o 7, from the sulfurous gas phase generated during multiple hearth roasting in molybdenum processing and smelting in copper processingnew technology platform called looping sulfide oxidation lso has been proposed.
