Phosphate rock grades are decreasing worldwide as the richer deposits are mined out.While there is plenty of low grade phosphate rock in the world which can be recovered it is becoming more expensive to produce good grade rock for easy processing into phosphoric acid and other fertilizer products.Beneficiation process of phosphate rock.
World phosphate grades the era of cheap, high grade phosphate rock in easily exploited reserves is over.Beneficiation.For many years it has been common practice to use flotation to upgrade mined phosphate to produce marketable phosphate rock.Originally mechanical flotation cells were used, and in most cases the amount of phosphate lost.
Yunnan some phosphate rock belongs to the low grade siliceous and calcareous collophanite, fine particles, the useful minerals and gangue minerals khenpo closely, more difficult to choose.The original ore dressing plant use direct reverse flotation process, but the disadvantages of large dosage, high temperature flotation.
Phosphate as fertilizer is so essential for agriculture plants growth.Most of the phosphate resources cannot be directly treated due to the low grade of p 2 o 5 and high content of impurities.Therefore, upgrading of this type of ore is so essential to achieving a grade of concentrate suitable for the production of fertilizer and phosphoric acid.
