Flotation is that process wherein, finely ground minerals are made hydrophobic so that they can be attached to air bubbles and separated in a frotha pH of 6 to 7. Flotation of quartz activated with calcium ions at pH 11 to 12 using a soap as the collector together with starch to depress the haematite. pac.iupac /.../pac/pdf/1970/pdf/2401x0135.pdfна сайте.
The quartz sand processing equipment used in this process is various types of suction mechanical agitation flotation cells and inflatable mechanical agitation flotation cells .
Flotation contact time for removal of impurities is usually short. A 4, and preferably a 6 cell, machine is advisable. Cell to cell pulp level control is also desirable. A 6 cell No. 24 Sub A Flotation Machine in most cases is adequate for handling 25 to 30 tons of sand per hour.
Before choosing a flotation cell, the quartz sand processing plant can choose a combined unit consisting of KYF flotation cell and XCF flotation cell according to its situation. Among them, XCF is used as a suction tank and KYF is used as a DC tank to achieve horizontal configuration without the need for a froth pump; the U shaped tank makes the flotation distance as short as possible, the pulp flows to the bottom of the tank, and the rotor is pumped to the gap between the impeller and the ...
