Chile has seven copper smelters, four that are linked to primary producers
(three owned by Codelco and one by Disputada) and three custom smelters (tw
o owned by Enami and one by Noranda). Each smelter employs a different stra
tegy for slag cleaning, thus each smelter obtains different results. This a
rticle outlines and compares the different sing-cleaning systems that are c
urrently in operation in the Chilean smelters, their strategies, the equipm
ent in use, and their experiences.
