Reverse Flotation Of Phosphate

  • Reverse flotation technology of phosphate ore in alkaline

    2013-12-31  The invention relates to a reverse flotation technology of phosphate ore in an alkaline medium. Crushed phosphate ore is crushed and evenly mixed with industrial lime, the mixture enters a grinder and water is added to perform size mixing. Thus, the ore is composed of materials and enters a reverse flotation roughing groove after the ore ...
