Low grade phosphate ore of Jhamarkotra that analyses 16.5% P2O5 is upgraded to 34% P2O5 by a two stage flotation process after size reducing the ore to 90% passing through 200mesh using conventional equipment such as jaw and cone crushers followed by ball mills.
Phosphate Ore Processing Grinding Plant
These tests also showed specific power consumption by the roller press to be 1.9 kWh per metric ton. After stabilization of the plant throughput and the process to give a consistent quality of phosphate concentrate at +34% P2O5, efforts were made to
improve the grinding circuit.The efficiency of grinding (Ball mill) may be 10% or still low. It is reported that 50% of the costs incurred in base metal concentrators is on grinding. CathayPhillips supply roller presses or High Pressure Grinding Rolls which is based on the principle of “crushing a mineral particle between other mineral particles instead of grinding elements.
Phosphate Ore Beneficiation Plant
Beneficiation of phosphate ores containing carbonate gangue minerals such as calcite and dolomite is one of the toughest problems before mineral process engineers, whereas phosphate ores with siliceous gangue can be processed by direct flotation of apatite minerals with soap collectors after deszenith the ore before milling.Cathayphillips supply advanced technology for Phosphate ore beneficiation.Our Phosphate Ore Beneficiation plants are used to process kaolin ore, marble , granite , iron ore ,copper ore , sandstone, silica , gold ore , silver ore , lead ore , manganese ore , tin ore and have exported to Indonesia, Vietnam , Iran, India, Chile, Venezuela, Libya, Angola, Kenya, South Africa, Pakistan , Yeman, Eygpt, Nigeria, Tajikistan , Saudi Arabia , Zimbabwe.
Phosphate Ore Flotation Process
The flotation circuits of the Jhamarkotra plant were constructed using Denver-Sala flotation cells (AS-9) of 9 m3 volume which were fitted with an impeller drive motor of 18.5 kW. Plant engineers carried out re-engineering of the flotation cells such that a single motor of 18.5 kW drives two cells of 9 m3 each. This brought down kW/m3 from 2.05 to 1.02. At the
same time by improving the airflow into the cells, the capacity of one line in the acid flotation circuit has been increased from 14 mtph to 32 mtph.
