[A pneumatic flotation machine consisting] of a long trough in the bottom of which is a longitudinal cylindrical rotor, covered with a porous medium, revolving slowly at about 15 revolutions per minute. The rotor is mounted at each end on hollow shafts extending out of the cell at each end through packing glands or through specially designed gland eliminators. Low-pressure air is introduced through the shaft at either end, or, for better control of aeration in various parts of the cell, the rotor may be divided into two sections and air introduced at both ends. The rotor is fitted with two longitudinal angle-iron scraper bars, which prevent settling and accumulation below it and thus protect the mat. The pulp enters at one end and is subjected to thorough aeration in passing through the machine. Froth overflows the sides, and tailings are discharged at the end by means of an adjustable weir overflow.  1, fiche 1, Anglais, - Callow%2DMacIntosh%20machine

Machines de flottation pneumatiques. Ces machines utilisent de l'air comprimé à la fois pour l'aération et pour l'agitation. [...] La cellule Callow-MacIntosh [...] comporte un rotor creux en acier perforé [...]. Ce rotor est entouré de toile ou de caoutchouc perforé. Elle présente l'avantage de se colmater difficilement [...]  1, fiche 1, Français, - cellule%20Callow%2DMacIntosh

Record number: 2, Textual support number: 1 DEF

Machine in which the air used to generate a mineralised froth is blown into the cell, either through a porous septum at or near the bottom, or by pipes which bring low-pressure air to that region.  4, fiche 2, Anglais, - pneumatic%20flotation%20cell

In pneumatic cells, the air flow also provides agitation of pulp. While the actual number of plants with air cells is relatively small, the majority of these units are used in concentration of copper ores and handle fairly large tonnages.  3, fiche 2, Anglais, - pneumatic%20flotation%20cell

A device that separates minerals from ore water pulp.  4, fiche 3, Anglais, - mechanical%20flotation%20cell

Record number: 3, Textual support number: 1 OBS

It consists of a cell in which the pulp is kept moving by an impeller at the bottom of the cell; the impeller pulls air down the standpipe and disperses it as air bubbles through the pipe; the floatable minerals concentrate in the froth above, and the pulp is removed by a scraper.  4, fiche 3, Anglais, - mechanical%20flotation%20cell

By contrast, pulp in the pneumatic flotation cell is agitated by air.  5, fiche 3, Anglais, - mechanical%20flotation%20cell
