Phosphate rock flotation in Uzbekistan

Flotation method: phosphorus minerals and gangue minerals are symbiotic, and the size of the inlay is fine. Only by flotation method can we obtain better separation effect. Therefore, the flotation method is Chinese phosphorus. One of the most used methods for ore dressing. The flotation method includes direct flotation, reverse flotation, anti-positive (positive-reverse) flotation and double reverse flotation. Direct flotation processes and reverse flotation processes are used in production practice. The direct flotation process employs an effective inhibitor to inhibit gangue minerals in the phosphate ore and concentrates the phosphorus minerals in the flotation foam with a collector.

Process Introduction

Flotation method: phosphorus minerals and gangue minerals are symbiotic, and the size of the inlay is fine. Only by flotation method can we obtain better separation effect. Therefore, the flotation method is Chinese phosphorus. One of the most used methods for ore dressing. The flotation method includes direct flotation, reverse flotation, anti-positive (positive-reverse) flotation and double reverse flotation. Direct flotation processes and reverse flotation processes are used in production practice. The direct flotation process employs an effective inhibitor to inhibit gangue minerals in the phosphate ore and concentrates the phosphorus minerals in the flotation foam with a collector.

The beneficiation process has been successfully applied to the ore dressing industry production of magmatic rock type apatite and sedimentary metamorphic apatite ore. The Jiangsu Jinping Phosphate ore dressing plant is a typical example. Sedimentary silico-calcium (calcium-silica) phosphate rock is recognized as a refractory phosphate rock in the world. Since the development of the direct flotation process of the "S" series of inhibitors, the ore dressing technology of this type of phosphorite ore has made a breakthrough. Reverse flotation process: The reverse flotation process is mainly used for the separation of phosphorus minerals and dolomite. The inorganic acid is used as the pH adjuster for the slurry. In the weakly acidic medium, the dolomite is floated with the fatty acid collector. Enriched in the tank product. The biggest advantage is that the room temperature flotation is realized, and the coarse particle size of the groove product is beneficial to the post-treatment of the product.The process has been successfully used in the beneficiation industry production of phosphate rock in Uzbekistan.
