Flotation in Mineral Processing | SpringerLink
Abstract. Few of the metals or minerals required by modern civilisation are mined naturally pure and ready to use. Instead they occur in complex aggregates of up to twenty different minerals of which only one or two will be of value. There are some two hundred of these 'value' minerals amoung the several thousand minerals that go to form ...

Flotation of Fine Particles: A Review: Mineral Processing …
Fine particles have a relatively high surface area, and therefore more reagents are needed for their processing. In addition, the problem of fine particle flotation is mainly due to their low collision and attachment efficiencies with bubbles. Several strategies are proposed in the literature to overcome the problems of fine particle flotation.

A review of mineral processing of ilmenite by flotation
However, solely flotation cannot be used to upgrade ores containing ilmenite, and in most cases, a pre-concentration process is needed prior to flotation. Here, a systematic review of reported technologies for ilmenite mineral processing is conducted in two parts, namely pre-concentration processing and flotation separation.
