The method was applied to the design of the flotation circuit that processes a material of four species, including CuFeS 2, FeS 2, AsFeS, and SiO 2; and to the retrofit of El Salvador flotation plant. Based on the results, it can be concluded that the method is an effective procedure for designing flotation circuits.

Fig. 5 (a) shows a 1% decrease in the cumulative mineral recovery when the particle size was increased by increasing the coarse material in the flotation bank. From laboratory and plant experiments, the finer classes (− 100#) showed a higher collection probability; therefore, a coarser feed decreases the global recovery of the flotation …

Flotation stands out as a successful and extensively employed method for separating valuable mineral particles from waste rock. The efficiency of this process is subjected to the distinct physicochemical attributes exhibited by various minerals.

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 ...
