| titleOfInvention | NEW POLYMERIC DEPRESSORS OF SULFIDE MINERALS |
| abstract | IT REFERS TO A POLYMERIC COMPOSITION OF RECURRING UNITS (CPUR) OF FORMULAS (I), (II) AND (III), WHERE EACH R IS HYDROGEN OR A C1-C4 ALKYL GROUP; R1 IS HYDROGEN OR METHYL; R2, R3 AND R4 ARE INDIVIDUALLY HYDROGEN OR A C1-C4 ALKYL GROUP; X IS HYDROGEN OR A HYDROXYL GROUP ON THE CONDITION THAT AT LEAST ONE X IS A HYDROXYL GROUP; x, y, z ARE MOLAR FRACTIONS COMPRISED BETWEEN 60% TO 98%, 1% TO 20%, 1% TO 20% RESPECTIVELY AND THE MOLECULAR WEIGHT OF THE POLYMER IS COMPRISED BETWEEN 1,000 AND 2,000,000; WHERE FURTHER THE UNITS x ARE UNITS OF ACRYLAMIDES, and ARE UNITS OF ALIL THIOUREA, AND z ARE UNITS OF HYDROXYETHYL METHACRYLATE OR DIHYDROXYPROPYL METHACRYLATE. IT FURTHER REFERS TO A METHOD FOR THE RECOVERY OF VALUABLE MINERALS (MV) OF MINES (M), WITH SELECTIVE REJECTION OF BARGAIN OR OTHER VALUABLE MATERIALS; WHICH INCLUDES: A) PROVIDING AN AQUEOUS PULP SUSPENSION (SP) OF PARTICLES FINALLY DIVIDED OF (M) OF SIZED RELEASE THAT CONTAIN SAID (MV) AND MINERALS OF BARGAIN; B) CONDITIONING SUCH (SP) WITH AN EFFECTIVE AMOUNT OF A BARGAIN DEPRESSOR (SAID (CPUR) OF FORMULAS (I), (II) AND (III)), A COLLECTOR OF (MV) AND A FOAMING AGENT; AND C) SUBMIT THE (SP) CONDITIONED TO FOAM FLOATING AND COLLECT THE (MV) THAT HAS A REDUCED CONTENT OF BARGAIN OR OTHER VALUABLE MATERIAL |
