high efficiency copper flotation from converter slags
Recovery of Copper from Converter Slags by Flotation.
Three slags containing 1.6, 5.0, and 6.6 percent copper were used. More than 90 percent of the copper was recovered in a rougher concentrate leaving a 0.2- to 0.3-percent copper tailings when treating slow-cooled slag. Lower recoveries and higher copper tailings ranging from 0.5 to 0.6 copper were obtained from quenched slag.

The results of the analysis showed that during the processing of sulfide copper concentrates in melting furnaces, due to the high partial pressure of oxygen, a large amount of magnetite compound appears in the system, which increases the density of the slag. An increase in slag density slows down the separation of the slag and matte phases.
