The Bureau of Mines conducted tests on seven samples of Florida phosphate operations slimes to develop a method to recover phosphate presently being discarded because of its small grain size. A system of hydrocyclones and hydroseparators was used to recover up to 96 pct of the plus 400-mesh material from the slimes. This plus 400- mesh material was subjected to fatty acid flotation, and concentrates containing up to 33.4 pct p2o5 were produced. As much as 88 pct of the phosphate (p2o5) was recovered from the plus 400- mesh material, and up to 29.6 pct was recovered from the total slimes.
