Most of the existing copper flotation plants dealing with copper ores containing a substantial amount of F have their unique way of minimising F recovery based on the ore mineralogy through flowsheet adjustment. The most successful approaches in minimising F recovery by flowsheet design and adjustment are discussed below. 2.3.1.1.

flotation models are linked. For example, a laboratory test conducted on a drill core sample, intended to represent a portion of the orebody, is conducted at a specific grind (represented by a P 80). However, when that ore is actually processed through the plant it may well be (and in many cases most likely will be) at another P 80 ...
