In the mining industry or extractive metallurgy, beneficiation is any process that improves (benefits) the economic value of the ore by removing the gangue minerals, which results in a higher grade product (concentrate) and a waste stream ().There are many different types of beneficiation, with each step furthering the concentration of the original ore. It helps make steel harder and water softer. It plays a part in dyeing cloth and in washing clothes. Phosphate is used in the cement a dentist uses on teeth and in the fluids used to drill for oil and gas. It is part of making cloth and helps to polish aluminum. And, phosphate is also used in making plastics, shaving cream, and bone china dishes.
World Phosphate Grades The era of cheap, high grade phosphate rock in easily exploited reserves is over. 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 Continued
