Process For Phosphate Beneficiation Google Patents

Process For Phosphate Beneficiation Google Patents

There are a variety of known techniques for removing impurities from solids, based on differences in characteristics between the pure solid and its impurities. For instance, materials can be separated based on their size, their density, their ability to hold an electrical charge, or their magnetic characteristics. These methods are useful for most solid separation applications, but there are some solids that cannot be economically separated by these methods because the pure solid and its impurit

Us Patent For Method For Defluorinating Wet Process

Us Patent For Method For Defluorinating Wet Process

A solution to this problem is to use a different characteristic, such as affinity for water, to separate the solid from its impurities. In one known method, ash a hydrophilic impurity is separated from coal a hydrophobic acid by forming a coal slurry, mixing oil into the slurry to produce agglomerates, and recovering the agglomerates as product. Most of the ash remains in the aqueous phase of the slurry.

A major disadvantage of this method is that the oil used to agglomerate the coal becomes part of the product. This means that this process could not be used to separate other hydrophobic materials from their hydrophilic impurities whenever oil would not be a desirable part of the final product. It is possible to try to recover the oil from the agglomerates, but this would require extremely high temperatures in excess of 260 C. and, even at these high temperatures, the oil recovery would not be c

It would be advantageous if a separation method could separate gangue minerals from phosphate rock by a process more energy efficient than the prior art processes. It would also be advantageous if a separation method could separate gangue materials from phosphate rock without agglomerates being in the final product.

In its broadest application, the present invention involves removing gangue minerals from phosphate rock by forming an aqueous slurry of the phosphate rock and gangue minerals then selectively agglomerating the phosphates in such a way as to agglomerate the phosphates, but not the gangue minerals. This selective agglomeration is carried out by the use of a nonpolar, water insoluble, bridging hydrocarbon. After the selective agglomeration takes place, the agglomerates can be separated by a screen

It has now been found through my study that certain surfactant such as fatty acid sulfonate, alkyl alcohol ether sulfate, N-substituted-N-mixed alkyloxy propylmaleimic acid derivative and alkyl alcohol sulfate combined with fatty acid can increase both recovery and selectivity of the existing flotation process. That has been proved in both bench tests and industrial tests. Therefore, the present invention provides a new anionic flotation agent for the beneficiation of phosphate ores comprising t
