Undersize drops by gravity to a 200 ton Fine Ore Bin. Plus ¼-inch oversize is passed through a set of Crushing Rolls which provide secondary crushing with a minimum size reduction of graphite particles. The crushing section is operated on an 8-hour per day basis, while the balance of the plant operates 24 hours per day. GRINDING …
They are fed regularly to the grinding circuit, to the flotation circuit, or to the conditioning tank. Collectors are the reagents that enable the desired mineral to become attached to the air bubbles in the pulp and thus float. The quantity of collectors used varies from 1/100 to ½ pound per ton of ore.
Flotation is a mineral separation process done in the water medium. It is based on the difference in the surface properties of the mineral and gangue.
The froth recovery of floatable mineral has been estimated by measuring the mass flowrate of particles entering the froth by true flotation together with the …
Flotation takes place by passing finely dispersed air bubbles through an aqueous suspension of particles (Fig. 17). A chemical reagent, called a frother, is normally added to promote the formation of small bubbles. Typical addition rates are in the order of 0.05 to 0.25 kg of reagent per tonne (0.1 to 0.5 lb per ton) of coal feed.
