EVALUATION OF THE ROUGHER FEED AND CONCENTRATE SIZE DISTRIBUTIONS FROM THE SALOBO SULPHIDE COPPER ORE PROCESSING PLANT
Salobo plant processes a gold and copper sulfide ore. The flotation process comprises the rougher, cleaner, and scavenger stages. Concentrate from the rougher and scavenger stages goes through a regrinding process before being fed into the cleaner stage. During the first years of operation, it was n...

This paper describes the results of field samplings and laboratory tests carried out to identify the factors behind such difference and to quantify it. Moreover, it shows the impacts of such size difference on the concentrate regrinding stage. |
