Reverse flotation : a novel process for the beneficiation

The beneficiation of ultrafine coal by froth flotation is a widely used process, and its importance for the treatment of -0.1 mm coal has been appreciated of late in South African coal washing plants. A number of problems adversely affect the efficiency of this process, such as poor liberation, poor floatability, gangue entraiment/entrapment

difficult-to-float coal fines of weak hydrophobicity (e.g., oxidized coal). Particle-bubble collision, attachment, and detachment are the most critical steps in the flotation process. It is known that the low flotation recovery of fine coal particles is mainly due to the low probability of bubble-particle collision. Fundamental analyses of froth

Imhoflot™ Pneumatic Flotation Plants

Imhoflot pneumatic flotation technology has evolved through 25 years of industrial applications. This has led to the development of the patented Imhoflot G-Cell where centrifugal forces are used in the cell to quickly separate the phases after mineral collection and therefore considerably reducing the size of vessels required.

FLOTATION SEPARATION OF FINE COAL PARTICLES FROM ASH

Mar 24, 2016Coal fines are mixed water under high shear mixing conditions to form an aqueous slurry of coal fines containing between 15 wt. % and 55 wt. % coal fines. The aqueous slurry is introduced into a coal flotation cell to separate coal particles from ash-forming component particles by flotation separation, wherein the coal fines have a particle

17th Perspective Trends in Fine Coal Slimes Flotation

ABSTRACT: Fine coal slimes (less than 0-0.2 mm) present great difficulty in cleaning. Their flotation ability depends on their size and physico-chemical characteristics. In particular, the degree of metamorpbism of the coal, and the proportion and ash content of super-fine coal particles (less than 50 pm) produces quite a strong
