More complete dewatering at the beginning of the process would address many of the unfavorable qualities of the mixes with lower percent solids. For example, FIPR and affiliated researchers from the University of Florida and the University of Kentucky conducted pilot studies of new types of sand-clay mixes using a variety of technologies.

Process for dewatering and utilization of mining wastes

Feb 01, 2004Flocculation was achieved by mixing the polymer solution with the clay slurry by pouring the slurry from one beaker to another 10 times. The flocculated slurry was then filtered, using a 12.5 cm dia. Buchner funnel and an aspirator (creating 0.5 atm of

and this water is decanted through spillways (dewatering). After standing water is removed, the phosphatic clays dry, or consolidate, further to approximately 15–18% solids. A crust forms on the surface, reducing evaporation and preventing further consolidation. The clays underneath the crust have a consistency often compared to pudding or

Recent technological breakthroughs in phosphate processing

Feb 01, 2012This paper gives a review of promising technologies for phosphate processing, and covers flotation, analysis and process control, as well as tailings treatment and utilization. Air bubbles of less than a μm in size, combined with relatively large bubbles, have been demonstrated, both in the lab and on a pilot scale, to improve flotation dramatically, by reducing reagent use while improving

FIELD DEMONSTRATION/EVALUATION OF A RAPID CLAY

Dec 02, 2014In 1991,FIPR initiated an in house research effort to investigate the effect of fibrous materials on dewateringand consolidation of flocculated phosphatic clay. As a result, the FIPR/DIPR process was developed and patented. DIPR stands for Dewatering Instantaneously withPulp R ecycle. The original FIPR/DIPR process involved treating
