    Arsenic is the main impurity present in copper concentrates, and is predicted to be above penalty limits in 10% of all copper concentrates produced in 2015. The arsenic content in copper concentrates is expected to grow from ~80,000 tonnes/year in 2013, to ~165,000 tonnes/year in 2020.

    Sulfide ores are used to produce a matte (40 50 wt % Cu) and a disposal slag (ca. 0.5 wt % Cu). In contrast, oxide ores are processed directly to impure black copper ( 95 wt % Cu) and to a copper rich slag. The two ore types can be smelted together to produce matte and a slag with low copper content.

    The copper ore was roasted in air, in nitrogen atmosphere and in vacuum at high temperature. It was found that arsenic was more easily removed in vacuum at lower temperature with shorter time. By suitably adjusting the main reaction conditions, almost 98.97% arsenic could be removed, while most of the sulfur was particularly retained in the copper ore.

    This process still does not remove arsenic, but rather concentrate it to the copper concentrate, since the copper mineral itself has arsenic as a main component. In some cases the copper concentrate may contain up to 10 15% As after flotation. The case is different if arsenic is present as arsenopyrite, FeAsS in the ore.

    Most ores contain less than 10% lead. Ores are crushed and concentrated by froth flotation typically to 70% or more. Sulfide ores are roasted, producing primarily lead oxide and a mixture of sulfates and silicates of lead and other metals contained in the ore. Lead oxide from the roasting process is reduced in a coke fired blast furnace.
