Process for the recovery of metal values

Claim 2

A PROCESS FOR THE RECOVERY OF METAL VALUES OCCURRING IN LIQUORS OR PULPS IN A CATIONIC FORM, COMPRISING THE STEPS OF INTRODUCING A CATIONIC EXCHANGE RESIN INTO THE LIQUOR OR PULP CONTAINING SAID METAL VALUES WHEREBY SAID METAL IONS MAY BE ADSORBED BY SAID RESIN, SAID CATIONIC ION-EXCHANGE RESINS BEING OF THE TYPE HAVING ACTIVE SULPHONATE GROUPS, ADDING AN AMOUNT OF A CATIONIC MATERIAL TO SAID LIQUOR OR PULP, SAID MATERIAL HAVING AN ACTIVE GROUP WHICH REACTS WITH SAID RESIN, SAID MATERIAL BEING SELECTED FROM THE GROUP CONSISTING OF THE AMINE-TYPE COLLECTORS AND THE CATIONIC SURFACE-ACTIVE TYPE PROMOTERS WITH ACTIVE AMINE GROUPS, AND BEING ADDED IN AMOUNTS BETWEEN .01 AND 1.0 LB. PER TON OF RESIN CONTENT OF SAID LIQUOR OR PULP, AND SAID MATERIAL BEING FURTHER CHARACTERIZED BY BEING ADAPTED TO IMPART WATER REPELLENCY AND AIRAVIDITY TO SAID RESIN, FLOATING SAID METAL-CONTAINING RESINS, THEREBY SEPARATING SAID RESINS FROM SAID LIQUOR OR PULP, AND TREATING THE FLOATED METAL-ION BEARING RESINS IN A SUITABLE MANNER TO REMOVE SAID METAL FROM THE RESIN, THEREBY RECOVERING SAID METAL VALUES.

Claim 3

A PROCESS FOR THE RECOVERY OF METAL VALUES OCCURRING IN LIQUORS OR PULPS IN AN ANIONIC FORM, COMPRISING THE STEPS OF INTRODUCING AN ANIONIC EXCHANGE RESIN INTO THE LIQUOR OR PULP CONTAINING SAID METAL VALUES WHEREBY SAID METAL IONS MAY BE ADSORBED BY SAID RESINS, SAID ANIONIC RESINS BEING OF THE STRONG BASE QUATERNARY AMINE TYPE, ADDING A SMALL BUT EFFECTIVE AMOUNT OF AN ANIONIC MATERIAL TO SAID SOLUTION OR PULP, SAID MATERIAL HAVING AN ACTIVE GROUP WHICH REACTS WITH SAID RESIN, SAID MATERIAL BEING SELECTED FROM THE GROUP CONSISTING OF ANIONIC SULPHONATE TYPE COLLECTORS AND ANIONIC SURFACE-ACTIVE TYPE PROMOTERS CONTAINING ACTIVE SULPHONATE GROUPS, AND BEING ADDED IN AMOUNTS BETWEEN ABOUT .01 AND 1.0 LB. PER TON OF RESIN CONTENT OF SAID LIQUOR OR PULP, AND SAID MATERIAL BEING FURTHER CHARACTERIZED BY BEING ADAPTED TO IMPART WATER REPELLENCY AND AIR-AVIDITY TO SAID RESIN, FLOATING SAID METAL-CONTAINING RESINS, THEREBY SEPARATING SAID RESINS FROM SAID LIQUOR OR PULP, AND TREATING THE FLOATED METAL-ION BEARING RESINS IN A SUITABLE MANNER TO REMOVE SAID METAL FROM THE RESIN, THEREBY RECOVERING SAID METAL VALUES.

Claim 4

A PROCESS FOR THE RECOVERY OF METAL VALUES OCCURRING IN LIQUORS OR PULPS IN AN ANIONIC FORM, COMPRISING THE STEPS OF INTRODUCING AN ANIONIC EXCHANGE RESIN INTO THE LIQUOR OR PULP CONTAINING SAID METAL VALUES WHEREBY SAID METAL IONS MAY BE ADSORBED BY SAID RESINS, SAID ANIONIC RESINS BEING OF THE STRONG BASE QUATERNARY AMINE TYPE, ADDING A SMALL BUT EFFECTIVE AMOUNT OF AN ANIONIC MATERIAL TO SAID SOLUTION OR PULP, SAID MATERIAL HAVING AN ACTIVE GROUP WHICH REACTS WITH SAID RESIN, SAID MATERIAL BEING SELECTED FROM THE GROUP CONSISTING OF ANIONIC SULPHONATE TYPE COLLECTORS AND ANIONIC SURFACE-ACTIVE TYPE PROMOTERS CONTAINING ACTIVE SULPHONATE GROUPS, AND BEING ADDED IN AMOUNTS BETWEEN ABOUT .01 AND 1.0 LB. PER TON OF RESIN CONTENT OF SAID LIQUOR OR PULP, AND SAID MATERIAL BEING FURTHER CHARACTERIZED BY BEING ADAPTED TO IMPART WATER REPELLENCY AND AIR-AVIDITY TO SAID RESIN, FLOATING SAID METAL-CONTAINING RESINS, THEREBY SEPARATING SAID RESINS FROM SAID LIQUOR OR PULP, AND TREATING THE FLOATED METAL-ION BEARING RESINS IN A SUITABLE MANNER TO REMOVE SAID METAL FROM THE RESIN, THEREBY RECOVERING SAID METAL VALUES.
