This article discusses the steps and setting necessary to evaluate the sulfur level in ore concentrates using the CS/S844. The efficiency of the concentration process can be determined using the sulfur level of the ore concentrate as a quality control measure. It can also be used to obtain an ...
A typical copper ore would be 0.7% to 2% copper, a typical copper concentrate would grade around 25% to 35% copper. Copper concentrates are either smelted and refined in-house, or sold to custom smelters. The concentrate may be smelted to produce blister copper for sale to a custom refinery, or the blister copper may be refined to cathode,
