Abstract
PURPOSE: To leach out P from granular or powdered ore while inhibiting the dissolution of the ore itself by immersing the one in an aqueous acid soln. having a specified concn. or below.
CONSTITUTION: Ore is crushed to granules or powder having ≤5, especially ≤2mm diameter. This granular or powdered ore is immersed in an aqueous soln. of a strong acid such as HCl, HNO3 or H2SO4 having ≤1.5% concn. The immersion time is ≥1, desirably ≥10hr when the temp. of the aqueous acid soln. is ordinary temp. By raising the immersion temp., the immersion time can be shorttened.
