A Kinetic Model for Conventional Flotation of Coal
Conventional flotation tests were performed on a coal sample obtained from the feed stream of a coal cleariing operation. Table 1 lists the particle size analysis for the sample as well as the composite assay. Prior to the flotation process, each sample was conditioned with fuel oil at 1.0 glkg of ore.

2020-4-8 In a conventional agitator-flotation system, bubbles and the opportunities for collisions between bubbles and particles are generated by mixing. Air is normally introduced by a blower, although self-aspiration is also possible. The technology is widely accepted by operators, and small cells can be supplied by local manufacturers.

Flotation process - Commonwealth Industrial Gases Limited
A typical flotation process involves the separation of the constituents of a mixed ore such as an ore containing the minerals galena (lead sulphide), sphalerite (ZnS) and pyrite (FeS 2). In a first stage, galena is floated by adding a xanthate collector (0.05-0.15 kg t -1 ore) to promote the flotation of galena.

A Kinetic Model for Conventional Flotation of Coal
The U.S. Bureau of Mines has developed a computer model to describe a flotation process. Coal data from conventional flotation has been converted to a simple, two-parameter kinetic model developed by Reuter and van Deventer (-l,2J3. Each set of coal data was represented by two constants, a and P, and an average flotation rate.

Recovery in phosphate ore flotation process - Allen, Warren J.
The material passing through the 150 mesh is called "slimes" and contains mostly clay, silica and phosphate. The slime is typically discarded in the conventional double flotation process. The usable ore typically (-20 to +150 mesh) is passed through a first flotation process for extracting the phosphate from the deslimed matrix.
