 Process Description
Phosphate rock from the mines is first sent to beneficiation units to separate sand and clay and to remove impurities. Steps used in beneficiation depend on the type of rock. A typical beneficiation unit for separating phosphate rock mined in Florida begins with wet screening to separate pebble rock that is larger than 1.43 millimeters (mm) (0.056 inch [in.]) or 14 mesh, and smaller than 6.35 mm (0.25 in.) from the balance of the rock. The pebble rock is shipped as pebble product. The material that is larger than 0.85 mm (0.033 in.), or 20 mesh, and smaller than 14 mesh is separated using hydrocyclones and finer mesh screens and is added to the pebble product. The fraction smaller than 20 mesh is treated by 2-stage flotation. The flotation process uses hydrophilic or hydrophobic chemical reagents with aeration to separate suspended particles. Phosphate Ore Beneficiation Technology Phosphate ore beneficiation technology may include filtration and/or drying, depending on the phosphoric acid plant requirements. Primary size reduction generally is accomplished by crushers (impact) and grinding mills. Some classification of the primary crushed rock may be necessary before secondary grinding (rod milling) takes place. The ground material then passes through hydrocyclones that are oriented in the countercurrent arrangement. Further processing in the form of chemical flotation may be required. Most of the processes are wet to facilitate material transport and to reduce dust. Phosphate Mining Equipment Phosphate mining equipment covers Vibrating feeder, Crusher, vibrating screen, XJK/SF flotation machine, mineral mixer, high frequency screen, screw ore classifier, concentrator, screw ore washer, ball mill/roller mill, coal gasifier, filter, rotary drier/rotary kiln, etc. The process is simple, purely physical beneficiation, phosphate rock will be placed in the water weathering scrub or peel grinding to remove surface mud material, so that phosphate enrichment. Less than the enrichment process, only to increase P2O5 grade 3 to 5 percentage points. The more typical and better results and is weathered phosphate mine. Steel Slag Beneficiation Equipment Shanghai Zenith professional production on a full set of energy-efficient processing 5-5000 tons of steel slag beneficiation equipment, various types of crushers, high energy ball mill, spiral classifier, flotation machine, drum, dryer, magnetic separator, thickener, vibration screens, feeders, conveyors, elevators and re-election of professional equipment manufacturers. Steel slag beneficiation equipment is mainly used in secondary crushing, and can crush material its crushing compression strength not more than 320 Mpa. It is suitable to produce aggregate ore for highway, hydroelectric and building materials industry, etc. Features of Steel Slag Beneficiation Equipment 1. Low and big feed opening makes the production line easy to arrange and increase the size of feeding material. 2. Reasonable design of leveling plate making charge finer and cubic without interior cracks. 3. Use the hydraulic to open, easy to maintain and change wear-parts.
