Show bubbles at work t Z rak flotation cells where minerals are lifted to top by bubbles bubble and saved for use in industry probably no other industry is subject to the varrance var yance ot of conditions as Is tle mining industry the fine line between success and failure of 0 it a mine is dependent upon many and varied conditions 0 of course there are a few high grade mines that can produce without much regard cr varying condl conditions but the yare very very tew few and do not last long it if they do one of 0 the things which the mining industry of 0 today relies so much upon Is the science 0 of notation flotation it if the mine can get its product past the flotation cells successfully it Is usually okeh but the dubbles cub bies which pick up tip the particles of 0 minerals in the flotation decide the future ot of many prospects and mines flotation Is a scientific development which has been applied to the low grade ores 0 of utah and other mining areas in a sense it la Is similar to the milling 0 of wheat it separates the wheat from the he chair chaff or the minerals from the waste or gangue after the ore has been finely ground it Is sent to the flotation cells where oil and other reagents are added the oils and reagents form bubbles when subjected to agitation in the notation flotation cells the bubbles percolate through the cells and come to the top in the form of 0 f troth froth the mineral particles have an affinity tor for the bubbles or oily roth froth and as they form on top of fit the cells are skimmed or allowed to float oft off the top ot of the cell the barren rock or gangue on oc the other hand has no affinity for or the oil all roth froth or bubbles and settles fettles to the bottom 0 of the flotation cell where it Is released and sent bent to the halings pond the flotation process Is reverse to tho the taws laws of 0 gravity the heavier particles the metal float to the top and are saved while the lighter particles sink to the bottom where they are discarded to the tailings pond |
