Due to copper minerals embedded in this materials at a very fine particle size, and closely symbiosis with iron content and quartz, lead to it difficult to enrichment through ore dressing methods.
The properties analysis of flotation concentrate Flotation concentrate as the raw materials for roasting.
But taking into account the value of materials and roasting operations consume large amounts of energy, so in order to reduce production costs, the roasting time should be shortened.
