METAL RECOVERY FROM A TANK BIOLEACHING SOLUTION WITH THE USE OF COATED MAGNETIC PARTICLES

摘要

Small magnetic particles are introduced into a solution which is subjected to a bioleaching process. The suspended particles are coated with a substance which has a selective affinity for, and which interacts with, a metal in the solution. The particles are removed from the solution and the metal is recovered from the particles by Resorption. The method enables direct recovery of silver from a bioleching solution in a tank and prevents undesirable silver precipitation.
