Froth Flotation (Sulphide Oxide)
You'll find that activated zinc will float a lot faster than the galena. The resultant tails will then, hopefully, look like a regular type lead/zinc ore (-2% galena, -7% sphalerite or so). This procedure was done in a lab test but again what we saw was activated zinc float prior to galena

24-09-2018The SAG mill products are then transferred to the two ball mills, where the ore is ground to a level of P80 = 80 μm. Lime and collectors Z11 and AP407 are added to the ball mill feed as well. Then, the product is discharged into a rougher flotation conditioning tank.
IsaMill
The IsaMill is an energy-efficient mineral industry grinding mill that was jointly developed in the 1990s by Mount Isa Mines Limited (MIM, a subsidiary of MIM Holdings Limited and now part of the Glencore Xstrata group of companies) and Netzsch Feinmahltechnik (Netzsch), a German manufacturer of bead mills. The IsaMill is primarily known for its ultrafine grinding applications in the

Guy and Trahar (1984) demonstrated that the oxidation–reduction environment during grinding had a pronounced influence on the subsequent floatability of galena.

Rod/Ball Mill| Eriez Lab Equipment. Flotation Cell,FULIN MINING. Principle of operation []. Before froth flotation can work, the ore to be treated is reduced to fine particles by crushing and grinding (a process known as comminution) so that the various minerals exist as physically separate grains.This process is known as liberation.The particle sizes are typically less than 0.1 mm (100 m
