Magnetic heavy medium treatment process and apparatus

Claim 1

IN A HEAVY MEDIUM TREATMENT PROCESS EMPLOYING A MAGNETIC MEDIUM, DELIVERING RINSE WATER CONTAINING MAGNETIC AND NON-MAGNETIC PARTICLES TO A PRIMARY MAGNETIC SEPARATOR, IN THE PRIMARY MAGNETIC SEPARATOR SEPARATING MOST OF THE MAGNETICS FROM THE WATER LEAVING THE WATER SUFFICIENTLY FREE FROM MAGNETICS TO RENDER THE WATER SUITABLE FOR USE AS PRE-RINSE WATER, UTILIZING THE GREATER PART OF SUCH MAGNETICS-CONTAINING WATER AS PRE-RINSE WATER, DELIVERING THE REMAINDER OF SUCH MAGNETICS-CONTAINING WATER TO A SECONDARY MAGNETIC SEPARATOR, CONTROLLABLY PREDETERMINING THE QUANTITY OF THE MAGNETICS-CONTAINING WATER UTILIZED AS PRE-RINSE WATER AND THE QUANTITY OF THE MAGNETICS-CONTAINING WATER DELIVERED TO THE SECONDARY MAGNETIC SEPARATOR, IN THE SECONDARY MAGNETIC SEPARATOR SEPARATING NEARLY ALL OF THE REMAINDER OF THE MAGNETICS FROM THE REMAINDER OF THE WATER, REMOVING FROM THE HEAVY MEDIUM CIRCUIT SUCH WATER CONTAINING NON-MAGNETIC PARTICLES TO PREVENT A BUILD-UP OF NON-MAGNETIC PARTICLES AND REUSING THE MAGNETICS RECOVERED IN THE PRIMARY AND SECONDARY MAGNETIC SEPARATORS.
