Process of froth flotation of ores

Claim 1

THE METHOD TO OPTIMIZE THE PROCESS OF FROTH FLOTATION OF ORES, WHICH COMPRISES PRE-DETERMINING BY A SERIES OF LABORATORY ROUGHER FLOTATION BATH TESTS ON THE ORES, THE VALUES OF THE CONTROLLABLE VARIABLES VIZ, FINENESS OF GRINED, PULP DENSITY, CHEMICAL COLLECTORM FROTHER AND MODIFIER REAGENTS, CONDITIONING TIME AND THE PH RESULTING FROM SAID VARIABLES THAT PRODUCE CONDITIONS OF MAXIMUM DIFFERENTIAL FLOATABILITY, AS DEFINED BY THE ALGEBRAIC DIFFERENCE OF THE MEAN RATES OF RECOVERIES OF THE VALUABLE MINERALS AND OF THE GANGUE IN THE FORTH CONCENTRATE DURING THE TOTAL FLOATION TIME INTERVAL OF THE BATCH TESTS; VARYING THE PROPORTIONS OF TWO CHEMICAL REAGENTS IN EACH SERIES OF TESTE FOR VARIOUS GRINDING FINENESSES AND FOR EACH OF VSRIOUS FIXED COMBUNATIONS OF OTHER REGENTS, PUPL DENSITIES AND CONDITIONING TIMES OF THE GROUND ORES; MEANS URING THE RESULTING PH CORRESPONDING TO EACH BATCH TEST OF EVERY SERIES; EXPRESSING THE CONDITIONS OF THE BATCH TESTS AS FUNCTIONS OF THE PAIR OF CHEMICAL REAGENTS VARIED, AS MEASURED ALONG THE COORDINATE AXES OF A CARTESIAN SYSTEM; NOTING AT THE PLOTTED POINTS THE DIFFERENTIAL FLOATABILITY OF EACH TEST, DRAWING CURVES OF EQUAL DIFFERENTIAL FLOATABILITY FOR THE EXPWRIMENTAL RESULTS OF EACH SERIES OF TESTS, THE ZERO CURVES REPRESENTING CONDITIONS OF NO SEPARATION OF THE VALUABLE MINERALS FROM THE GANGUE, POSITIVES CURVES REPRESENTING CONDITIONS OF CONCENTRATION OF THE VALUABLE MINERALS IN THE FORTH, AND NEGATIVE CURVES REPRESENTING CONDITIONS OF CONCENTRATION OF THE GANGUE IN THE FORTH; TAKING FROM SAID EQUAL-DIFFERENTIAL FLOATABILITY CURVES THE BEST RELATIVE PROPORTION INDICATED BY THE RESPECTIVE COORDIANTES OF THE PAIR OF CHEMICAL REAGENTS WHICH PRODUCES THE GREATEST ABSOLUTE VALUE, POSITIVE OR NEGATIVE, FOR THE DIFFERENTIAL FLOATABILITY IN EACH SERIES OF TESTS, DEFINING THUS THE CONDITIONS CORRESPONDING TO THE MAXIMUM DIFFERENTIAL FLOATABILITY OF ALL THE SERIES OF TESTS, FOR THE TREATMENT OF ANY ORE IN TERMS OF THE CONTROLLABLE VARIABLES OF THE PROCESS, AND THEIR RESULTANT PH.
