The process plant in Navoi region is necessary to increase the concentration of P205, remove water-soluble chlorides from phosphorite ore in order to obtain raw materials for Samarkand chemical plant. The annual capacity of Process Plant for ore is 2 million tons. The raw product used for production of clean products is low-grade phosphate rock. The design is carried out using the most modern solutions: BIM modeling, strength and hydraulic calculations using the finite element method.
BCS technical data:
- Ore throughput, tons per hour 250
- Ore throughput, million tons per annum 2.0
- P2O5 content in ore,% 18.04
- P2O5 content in concentrate,% 22.68
- Concentrate moisture,% 1.0
- Chloride content,% 0.04
- Number of trains, ea. 2
- Total power, MW 10.5
Main process facilities:
- Open-type ore storage (receiving hopper, feed unit)
- Flushing section with a capacity of 2 lines, 125 t/h each, consisting of the following stages and facilities:
- Disintegration (Trommel rotary screen)
- Wet Screening (Vibration Screen)
- Desludging (Hydrocyclones)
- Grinding (Mill)
- Filtration (Vacuum filter)
- Drying section (Drum dryers)
- Unit for thickening and pumping sludge with a unit for preparing and dosing flocculant (Thickener)
- Compressor plant with receivers for flanges
- Out of balance ore bin +5 mm
- Out of balance ore stockpile +5 mm
- Stockpile of finished goods at the Process Plant with unloading into tank trucks
- Stockpile of clean concentrate with return unloading to the drying line
- Stockpile of finished goods at Tashkura station with unloading into railroad cars
The process plant project will create about 500 new work places following startup.
