摘要：
THE DISCLOSURE DESCRIBES A PROCESS FOR CONTROLLING THE AGGLOMERATION OF CADMIUM PRECIPITATE PARTICLES DURING THE PURIFICATION OF A ZINC SULFATE SOLUTION TO PREVENT THE BUILDUP OF LARGE BALLS OF CADMIUM PARTICLES WHICH MAY DAMAGE THE PROCESSING EQUIPMENT. THE CONTROL IS PROVIDED BY THE ADDITION OF SMALL AMOUNTS OF SOLUTION SOLUTION SULPHUROUS ACID GENERATING MATERIAL TO A LEACH SOLUTION.
