The alabama oil shale used in the present study contained 16.46 organic carbon and 14.5 gallons of oil per ton as determined by fischer assay. liberation size of the kerogen was estimated at 10 181m. kenflote column flotation technology provided a high grade concentrate containing as

Columnlike performance in a substantially smaller footprint. these compact, stackable units offer considerable savings for new installations and are ideal for expanding capacity in an existing plant. a new highcapacity flotation technology, the stackcell, has been developed as an alternative to both conventional and column flotation machines.

The bubble slurry was pumped to the flotation unit at 1,000 mlmin. the bubble slurry flow into the flotation cell produced an upward flow velocity of 22 cmmin between the bubble sparger and the top of the flotation column, as shown in figure 7. virtually all of the water in the bubble slurry exited the column cell with the flotation concentrate.

Jul 15, 2019nbsp018332column flotation is, however, limited by the mass of concentrate recovered 3,4, because of the small diametertoheight ratio, that is, the ratio of froth surface area to pulp volume 5,6. this ratio places a severe limit on the throughput of a flotation column 7,8. a considerable amount of research work, especially in the 1960s and 1970s ...

Operating cost savings can be realized from reduced power requirements, reduced maintenance costs and in some cases reduced reagent consumption. power costs are typically 50 lower than an equivalent mechanical flotation circuit. column cells have very low maintenance requirements and low inventory requirements.

The ability to use wash water to remove entrainment revived the interest in flotation columns. ld ratio is also significant for ultrafine particles. the coal industry is shifting to larger columns, up to 4.5m diameter and greater.

The amount of phosphogypsum produced using concentrate from the carbonate flotation process is about 3 less than phosphogypsum produced with untreated feed. this amounts to a reduction of over 42,000 tons per year for a 1,000 tpd p 2 0 5 phosphoric acid plant. using the jacobs dapcost model, a 7.06 per ton dap cost savings is projected.

Existing flotation machines work very well for sizes typically in the range of 50 to 150 m. if the upper size limit for flotation could be increased, by innovations in machine design, there would be dramatic reductions in grinding energy, which would lead to savings of great consequence for the running costs of the whole operation.

Coarse flotation offers important savings through reduced operating costs grinding cost varies greatly depending upon the size reduction required. for example, it takes approximately 50 less horsepower to grind from 189 to 48 mesh than it does to grind the same material from 189 to 100 mesh.
