Phosphate slimes contain 6 to 17 pct P, which in some cases amounts to almost one-third of the phosphate in the matrix (1). Recov­ ery of phosphate from the slimes would lengthen the life of domestic phosphate reserves. Florida phosphate slimes have been ex­ tensively characterized by the Bureau of.

Assuming an average P concentration of 12% in the past slimes, simple multiplication says that almost million tons of P (an equivalent of million tons of phosphate rock with a P of 30%) have been discarded with the phosphatic clays in Florida alone. ZHANG and M.

These slimes represent a significant ecological problem and a major deterrent to effective land recovery in the phosphate-mining areas. EPA/ March ELIMINATION OF WASHER SLIMES FROM THE PRODUCTION OF PHOSPHATE CHEMICALS by Raybon C.

ZHANG, Y. YU and M. BOGAN Florida Institute of Phosphate. Florida's phosphate deposits lie below the earth's surface at depths of about 15 to feet. The soil is stripped away in immense ditches and piled to one side. The discarded slimes, not only ac- count for heavy losses (up to 60%) of P values, but also pose problems in their safe disposal (USBM, ; Pradip, ).

The feasibility of using selective flocculation techniques to recover values from phosphate slimes has been investigated by a number of investigators (Davenport et al., ; Pradip et. Recovery of phosphate values from slimes by selective flocculation.

In: S.P. Meh- rotra and T.R. Ramachandran (Editors), Progress in Metallurgical Research Fundamentals and Applied Aspects. McGraw-Hill, New York, NY, pp. To meet the growing global demand for rare earth elements (REEs), nontraditional mining sources of these metals are being investigated.

Phosphate ore and phosphate mining wastes have been identified as possible alternative sources to REEs. In this study, REEs were extracted from Florida phosphate mining materials using mineral and organic acids. The REEs were then recovered at high.

“Slime” ponds. Florida’s phosphate belt is concentrated in four fast-growing rural counties east of Tampa, and the sheer magnitude of the operations is staggering. Someacres have already been mined, and phosphate companies own or control an additional— an. 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 mesh material from the slimes. This plus mesh material was subjected to fatty acid flotation, and concentr.

The EPA estimates that the current stockpile of waste in Central Florida’s gypsum stacks has reached “nearly 1 billion metric tons.” (The average gypsum stack takes up about acres of surface area – equal to about football fields – and can go as high as feet.).

The Bureau of Mines conducted tests on samples of two Florida phosphate slimes to devise a technique to recover phosphate currently discarded because of its fine size.

A flotation technique was devised to recover the phosphate contained in two fractions of each slime: the plus um fraction and the plus um fraction. The three main causes of Florida's phosphate industry's financial problems are foreign competition, the financial problems of farmers in the United States and the strength of the United States' dollar.

Gypsum slurry transport water in mills using Florida phosphate rock is extremely acidic, with. Phosphorite, or phosphate rock, is the raw material of phosphoric acid production. It has also been regarded as the most important secondary rare earth element (REE) resource due to low contents of rare earth elements contained in the ore.

In Florida, there is about 19 Mt of phosphate rock mined annually. After beneficiation, the phosphate rock concentrate is utilized to produce phosphoric.

About 1 billion tons of phosphate­ rock concentrate, containing an average of about 32 percent P20s, have been produced since the start of mining in Phosphate mining in Florida was initially confined to high-grade deposits in Polk and Hillsborough Counties.

The major problems. Florida has two major phosphate deposits: the Bone Valley Formation and the Hawthorn Formation. The high grade, easy-to-process Bone Valley deposit is being depleted rapidly, and the mining industry is moving south/southwest to the Southern Extension of Bone.

And phosphate mining in Florida, which is home to the world’s largest phosphate mine, is being challenged by environmentalists concerned about its impact on waterways and drinking water supplies.

Already, like other key commodities with once-dominant sources running low, the price of phosphate is starting to yo-yo alarmingly.
