surfactant-coated dolomitic phosphate pebbles were immersed in a 3% sulfuric acid solution, effectively all the high MgO particles would float to the surface, leaving the phosphate rock phase that is low in MgO to sink. The best coating agent was found to be polyvinyl alcohol (PVA). The table below summarizes results from two encouraging tests.
Phosphate Beneficiation. Market Specifications Bone phosphate of lime, 70 to 72 per cent, common. Bone phosphate of lime 72 to 77 per cent, premium. Production Problems. Phosphate rock being a low-priced material is produced as near the fertilizer market as possible and haulage costs determine production.
Florida phosphate mining process - The Mosaic.Phosphate Mining And Beneficiation Of Rock Phosphate rock is usually found 15-50 feet beneath the ground in a mixture of processing facility, referred to as a beneficiation plant, where phosphate rock isValorization of Phosphate Waste Rocks and Sludge.Sedimentary phosphate .
dolomitic impurity level to less than 1.0 weight percent MgO in the concentrate, as stipulated by the phosphate industry. During the past decade, studies conducted by investigators in the Florida phosphate industry [2,3,4,5] and the Tennessee Valley Authority  have resulted in the development of a number of processes.

INTRODUCTION Phosphate rock is a vital, nonrenewable and non-substitutable mineral resource. The demand must be met through mining, beneficiation and chemical processing of naturally derived materials.
Phosphate Beneficiation. Background. Definition of "Beneficiation": This is the second step in the mining process, after removal of the ore from the ground. Beneficiation is the technical term describing the industrial process of mechanically separating minerals from each other.

Treating high-mgo ores with present beneficiation technology will not yield a concentrate meeting specifications for acidulation. The Bureau of Mines conducted research on three high- mgo phosphate samples from south Florida. The samples contained, in percent, 5.4 to 10.2 P2o5, 1.9 to 7.6 Mgo, and 35.3 to 60.1 Acid insolubles.

Abstract. Dolomite [CaMg(CO3)2] is an intolerable impurity in phosphate ores due to its MgO content. Traditionally, the Florida phosphate industry has avoided mining high-MgO phosphate reserves due to the lack of an economically viable process for removal of dolomite.
Beneficiation of Phosphate Ore thoroughly explains the methods used in beneficiation of different types of phosphate ores for use in the wet process. The mineralogical properties of the two major types of phosphate deposits, sedimentary and igneous, are described along with the processing methods.
The beneficiation of phosphate rock can often be simplified and made more economic by taking into account the distribution of P 2 O 5 and impurities as a function of their deportment between the size fractions resulting from mined and comminuted sedimentary phosphates.
