flotation using flocculants for copper sulphide ore

Organic flocculants can be divided into two main groups: natural and synthetic flocculants. ore, mafic extrusive rocks–epithermal ores, and copper–zinc scarns. In the flotation of copper–zinc massive sulfide ores, the flotation properties of copper and zinc are determined by the nature and composition of the ore. In the treatmentget price

The FF (flocculation–flotation) process ScienceDirect

2005-6-1  A new on-line flocculation system (FF) has been developed which is coupled with a rapid flotation to remove the aerated flocs (flocs with entrained and entrapped bubbles). These aerated flocs are formed only in the presence of high molecular weight polymers and bubbles and under high shearing (and head loss) in special “flocculators”.
