study the use of cellulase enzyme as a new phosphate depressant during fatty acid flotation of a calcareous phosphate rock. The flotation behavior of collophane and dolomite as single minerals using oleic acid as a collector and cellulase enzyme as the phosphate depressant was investigated in details.
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, de-, magnetic separation or flotation.
In this study, a new flotation method is described which was applied successfully in a laboratory scale flotation cell. Flotation of Al-Jalamid phosphate rock (sedimentary type with high carbonates and low silica content) found in northern Saudi Arabia was studied using a fatty acid as collector and sodium sulfate as a flotation aid.

The first commercial production of phosphate rock began in England in 1847. A wide variety of techniques and equipment is used to mine and process phosphate rocks in order to beneficiate low-grade ores and remove impurities. The eighth chapter of this book deals with mining and beneficiation of phosphate ore. The principle and operating conditions of important parts of manufacturing process ...
Froth flotation is a process for separating minerals from gangue by taking advantage of differences in their hydrophobicity.Hydrophobicity differences between valuable minerals and waste gangue are increased through the use of surfactants and wetting agents.
A process for the froth flotation separation of phosphate containing minerals by the use of a new collector agent is described. The new phosphate collector agent is prepared by mixing a fatty acid, tall oil pitch, an amine, and optionally sarcosine with fuel or furnace oil, and subsequently oxidizing the mixture by known methods. The new phosphate collector agent is added to the conditioned ...
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 30-32% P2O5 content. The growing fertilizer industry has increased the demand for phosphate rock from which super-phosphates are produced. The fertilizer market is very competitive.

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 ...
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).
