Copper Mining & Processing: Everything You Need to Know
However, concentration methods such as froth floatation separate the copper minerals from the waste rock for more tricky ores, such as sulfide ores. The sulfide ore is then roasted or smelted into a purer copper concentrate called a slab. Finally, the copper slab undergoes electrolysis, resulting in 99.99% pure copper cathode slabs.

Model Predictive Control of SAG Mills and Flotation …
Use of the Laguerre process model implicitly assumes that a self-regulating process is to be modeled. In cases where a process exhibits integrating behaviour, such as SAG mills can exhibit at high loads, it is necessary to modify the Laguerre process model. The modification is two-fold. First, the .
