Metix has introduced a three-piece 'deep-cooled' copper slag tapblock into a six in-line copper matte settling electric furnace. The tapblock was designed without any internal refractory; it ...

The copper smelting process produces plenty of copper slag every year, which is a hazardous solid waste, but a secondary resource. In the present study, the extraction of copper, nickel, and cobalt from copper slag was investigated through the process of sulfation roasting–water leaching and the process of sulfation roasting–sulfate …

detailed analysis of copper slag, adjustment is to be done in the optimum value by considering that above 20.1 %. This value resulted to be compatible with the results of pozzolanic tests. In the Table 1, are shown the mechanical stren-gths of hardened mortars prepared with various con-tent of copper slag as substitute of Portland cement.

Copper slag is composed of iron silicate obtained by smelting copper concentrate and silica flux.
