increase this maximum capacity for a single roasting line up to 1,800 t/d of concentrate. From an economic and technical standpoint, this throughput can only be achieved for one line by applying circulating fluid bed technology. In similar applications, the throughput e.g. in whole ore gold roasting plants can reach up to 3,800 t/d.

Roasting is a process of heating of sulfide ore to a high temperature in presence of air. It is a step of the processing of certain ores.More specifically, roasting is a metallurgical process involving gas–solid reactions at elevated temperatures with the goal of purifying the metal component(s). Often before roasting, the ore has already been partially purified, e.g. by froth flotation.
