Abstract
Abstract Mineral concentrates are obtained from aluminosilicate and alkali and alkaline earth aluminosilicate, phosphate and fluoride ores in a beneficiation process in which the ore is conditioned prior to flotation with a C20 to C22 saturated or unsaturated fatty acid or a mixture of C20 to C22 saturated or unsaturated fatty acids and C18 or lower fatty acids and an alicyclic or aromatic hydrocarbon oil.

Claim 1
Independent Claim
171 words
IN A BENEFICIATION PROCESS INCLUDING FROTH FLOTATION OF GROUND ORE TO PROVIDE A MINERAL CONCENTRATE FROM AN ORE SELECTED FROM THE GROUP CONSISTING OF ALUMINOSILICATE AND ALKALI AND ALKALINE EARTH METAL ALUMINOSILICATE, PHOSPHATE AND FLUORIDE ORES, THE IMPROVEMENT CONSISTING ESSENTIALLY OF CONDITIONING THE GROUND ORE PRIOR TO FLOTATION WITH FROM ABOUT 0.25 TO ABOUT 4 LBS. PER TON OF ORE BASED ON THE ORE BEING TREATED, OF A FATTY ACID COLLECTING AID SAID FATTY ACID BEING SELECTED FROM THE GROUP CONSISTING OF A FATTY ACID CONTAINING 20 TO 22 CARBON ATOMS AND A MIXTURE OF FATTY ACIDS CONTAINING FROM ABOUT 15 TO ABOUT 75% OF A FATTY ACID CONTAINING 20 TO 22 CARBON ATOMS, BALANCE C18, OR LOWER FATTY ACIDS, SAID PERCENTAGE BEING BY WEIGHT, BASED ON THE WEIGHT OF THE FATTY ACID MIXTURE AND FROM ABOUT 0.05 TO ABOUT 1 LB. PER TON OF ORE, BASED ON THE ORE BEING TREATED OF AN ALICYCLIC OR AROMATIC HYDROCARBON OIL SELECTED FROM THE GROUP CONSISTING OF TURPENTINE, PINENE, MESITYLENE, CEDRENE AND 1,3-DICYCLOPENTADIENE.

Claim 3
Dependent Claim
52 words
The process of claim 1 wherein said fatty acid component of the collecting aid is a fatty acid containing 20 to 22 carbon atoms said fatty acid being a member of the group consisting of saturated fatty acids, unsaturated fatty acids or mixtures of saturated and unsaturated fatty acids in any proportion.
Claim 4
Dependent Claim
12 words

Claim 5
Dependent Claim
57 words
The process of claim 1 wherein said fatty acid component of the collecting aid is a mixture of fatty acids containing from about 15% to about 75% of a fatty acid containing 20 to 22 carbon atoms, balance C18 or lower fatty acids, said percentage being by weight based on the weight of the fatty acid mixture.
Claim 6
Dependent Claim
