Karimova L.M. Sulphatizing roasting of a rough copper sulfide concentrate for sulfuric acid leaching

Abstract

To assess the integrity and impact resistance when loading, transporting and storing pellets of a rough copper concentrate, we calculated the allowable height of bins from the pelletizer to the shaft furnace. Influence of various factors on roasting of the rough copper flotation concentrate was studied in the laboratory of the shaft furnace. We revealed extreme dependence between the temperature and copper extraction. Depending on the existing factors we obtained partial and generalized functions of copper recovery into the solution and the transition of sulfur in gas.

Keywords

Pellets, copper concentrate, bed height, roasting, factors, generalized equation.
