Concentration
in metallurgy is the oxidation process that may have several purposes, but the
main goal is to remove the entire concentration quantity S (sulphur), or a part
thereof from ore. Depending on the conditions and technical parameters in the
furnace for concentration process, a portion of the sulphur can be converted to
sulphate or not oxidized and be present in concentration. If the ore is present
FeS2 often what happens during
concentration decomposed into FeS and FeS2.
Concentration process usually requires excess air for reactions that  decomposes during concentration so that any
part of the ore to be in contact with air O2.For
this work at all times, the furnace for concentration should be done ore
blending. The quantity of air that inflates and his preheating represents one
of the most important factors of the concentration process of copper ore in
furnaces for concentration.
