Flotation Process Parameters | SpringerLink
Flotation process parameters is the flotation process optimized by a set of parameters, which include but are not limited to (1) Grinding size. Flotation requires not only mineral liberation but also the appropriate feed particle size. The maximum particle size in flotation was limited and varied according to its density.
Vibrating Feeder
The vibrating screen feeder is mainly used in the following situations: (1) It can be continuously fed before coarse crushing and screening to separate fine particles and improve crushing capacity. (2) During the operation, the materials are fed into the feeding device evenly, regularly and continuously.

Influence of hydrodynamics on preflotation process in flotation machine
This paper presents the results of an investigation into the influence of hydrodynamics on a preflotation process for the copper sulfide ore from the Fore-Sudetic Monocline deposits in Poland in a flotation machine. The main aim of the preflotation stage for Polish copper ore is to remove the easy-to-float organic matter — organic carbon — …
