Microcrystalline and cryptocrystalline low-grade colloidal phosphate ore beneficiation process

Microcrystalline and cryptocrystalline low grade phosphate ore beneficiation process, comprising the steps of: (1) ore crushing, wet milled to a content of 90-92%, -200 mesh fineness; desliming (2) flotation (3) Phosphate positive flotation; (4) Carbonate reverse flotation, the product in the tank after reverse flotation sweeping operation is the final product phosphorus concentrate. The invention is used for sorting low-grade colloidal phosphate ore, which overcomes the shortcomings of the previous single positive flotation that cannot obtain qualified phosphate concentrate, and the content of harmful impurities of the obtained phosphorus concentrate can be reduced to 1.78%, reaching the wet-process phosphoric acid product. Phosphate concentrate requirements; the invention overcomes the disadvantages of low recovery rate and high energy consumption of the calcination-digestion-screw beneficiation concentrate.

Round Open Water Cooling Tower

The whole structure is solid and light;the body and water pond is manufactured with reinforced glass fibre (FRP glass fiber reinforced plastics),never being corrosive. The surface finish is added with ultraviolet inhibitor,which can resist sunshine attack and damage.

All steel and iron material is processed through galvanizing by dipping,Ocorrosion resisting and durable.

Special designed axial-flow type air blower applies belt reduction gear,reducing low noise and sufficient wind; tailor-made water-drop noise
reduction carpet to eliminate water sound.

Apply special design PVC water block curtain (water-stop) to prevents plashing) remarkably; pressure drop loss is slight and splashing loss i under 0.001%.
