For Phosphate, flotation is, in general, very important to upgrading the phosphate rock and is employed in this study to beneficiate a 20% P2O5 feed content to a 3032% P2O5 content. The growing fertilizer industry has increased the demand for phosphate rock from which superphosphates are produced. The fertilizer market is very competitive.
Different types and structures of reagents are used in the flotation of phosphate ores as collectors, depressants, and auxiliary reagents in direct and reverse flotation of phosphate ores. In direct flotation, phosphate minerals are floated at basic pH with usually anionic collectors and depressant/modifier for gangue minerals.
froth flotation cells. The process of froth flotation entails crushing and grinding the ore to a fine size. This fine grinding separates the individual mineral particles from the waste rock and other mineral particles. The grinding is normally done in water with the resultant slurry called the pulp.

The Standard Industrial Classification (SIC) code for phosphate rock processing is 1475. The ...
agents, food preservatives, insecticides, and many other products. World demands for phosphate are expected to double within the next decade. Although known supplies are adequate to meet world needs for many years, additional sources are needed in regions that contain no known minable deposits, for phosphate rock is a
Flotation was discovered early in the 20th century, and today it is the most commonly used separation technology in the mining industry. Flotation separates valuable minerals (copper, lead, zinc, iron, and phosphate too) from the contaminating minerals in the ore (sand in this case).

Large scale mining and processing of phosphate is essential for operating at a profit. In the Florida area, Phosphate Beneficiation by flotation unlocked the door to vast tonnages of ore which in the past could not be recovered by conventional washing methods which saved only the coarser pebble phosphate. Many of the areas now being mined contain very little or no pebble phosphate, so the main ...
ENHANCED PHOSPHATE FLOTATION USING NOVEL DEPRESSANTS Froth flotation is the most efficient method for phosphate separation, which is a physicchemical separation process based on the difference of surface properties between the valuable minerals and unwanted gangue minerals. However, the presence of clay
The phosphate content of phosphorite (or grade of phosphate rock) varies greatly, from 4% to 20% phosphorus pentoxide (P 2 O 5). Marketed phosphate rock is enriched ("beneficiated") to at least 28%, often more than 30% P 2 O 5. This occurs through washing, screening, deliming, magnetic separation or flotation.
