Ausmelt furnace slag contains about % Cu mass % With increasing the amount of Ausmelt furnace slag the recovery of copper from it will produce an enormous economic yield The recovery of copper by floatation from slow cooled Ausmelt furnace slag was studied
·converter slag is nearly twice as hard to grind as copper ore The high consumption of grinding media is an important cost factor in slag milling and has led to the adoption of autogenous grinding at the Harjavalta smelter However the Hitachi and Naoshima smelters use cast iron balls for grinding
·lead blast furnaces and copper slag granulation had learned that the presentation of the molten material into the water was very important Gr anulation into wet launde rs was an old practice
·1 Introduction As the cumulative amount of industrial solid wastes ISWs containing aluminosilicate components exceeds billions of tons [1] ISWs have been regarded as perfect candidates for replacing cement in concrete such as granulated blast furnace slag GBFS fly ash steel slag and copper slag CS are commonly used as
·Alkali activated copper and nickel slag cementitious materials ACNCMs are composite cementitious materials with CNS copper and nickel slag as the main materials and GGBFS ground granulated blast furnace slag as a mineral admixture In this paper the activity indexes of CNS with different grinding times were studied using CNS to replace a portion of
·Grinding of copper slag to be less than 100 mesh and then fed through flotation cell was tried to obtained copper concentrate containg % Cu with the higher recovery of % The copper
·Copper slag abrasive has a higher density than coal slag resulting in faster blasting and reduced product consumption Copper slag is also used in other applications such as grinding wheels garment and textile blasting jean and clothing sandblasting offshore oil pipeline blasting waterjet cutting and roofing granules It can also be
·However recovery of copper was about 4 percent lower for the high copper slag sample C and 23 percent lower for the low copper slag sample A Flotation tailings from the quenched slags ranged from to percent; slow cooled slags gave tailings containing from only to percent copper with lowest analyses for 30 minute grinds
