Flotation contact time required for the ore is one of the determining factors in calculating flotation cell capacity. If an ore is slow floating and requires twelve minute treatment time, and another ore is fast floating and requires but six minute treatment, it is evident that a machine of only half the capacity is necessary in the last instance.

Such basic factors as knowledge of mineral structure, chemical reagents, pH of mill water, pulp density, temperature, technical skills of the operator, the dependability of the flotation machine, as well as a host of other factors which affect the flotation of each specific ore must be combined …
Froth flotation is the most effective industrial method used to separate fine-grained minerals. The main problem of complex ore flotation is the negative effect of interactions among minerals in slurry, leading to variation in surface properties during separation. In this review, studies on the interactive effect among minerals on the flotation of iron ores, magnesite ores, …
FLOTATION Flotation is the most widely used mineral separation method. It is the preferred method of mineral recovery for many of the most important minerals that are recovered and large tonnages of ore are processed by flotation annually. The underlying principles of the flotation process are well established but it has proved to be
Flotation machines, in general, may be categorized into four different classes: (i) mechanical or con-ventional cells; (ii) energy-intensive pneumatic cells; (iii) column cells; and (iv) froth …
