Two reasons justify concentrating on converter operation. First, the main bottlenecks in smelter operation result from converter constraints. Secondly, converter operation strongly influences copper yield and loss. Few scheduling solutions have been previously reported in relation to copper smelter optimization.The Mount Isa Copper Concentrator grinding circuit currently consists of two 32' x 16' semi-autogenous (SAG) mills, each powered by two 3.2 MW motors, followed by two 16'6" x 20' ball ...

As part of the program you should take a sample of your rougher concentrate and look at it under a microscope - if there is a lot of pyrite is it liberated or associated with the copper minerals. If it is the former then there are opportunities to optimize flotation. If it is the latter then you need to look at finer grinding.The grade of the concentrate is 36 to 40% TCu. The plant efficiency (recovery) is at 89% TCu. The concentrator operations include: Primary, secondary and tertiary crushing, grinding, flotation, dewatering and …
