conjunction with fuel oil.- These and similar reagents act to selectively oil the oxygen-bearing ore particles which may then be collected by various methods such as tabling, stratifying, agglomeration or film flotation and like processes,
or by froth flotation in the presence of a frothingreagent such as pine oil.
In accordance with the present invention it has been discovered that aliphatic alcohol esters of unsubstituted higher fatty acids can be employed to replace the various collecting or pro- 29 moting reagents that have been used in the oxygen-bearing mineral concentrating operations heretofore. For example, the aliphatic alcohol fatty acid esters of this invention can be used to replace the free fatty acids, the fatty acid 5 soaps, the fish oil fatty acids, etc., in the concentration of oxygen-bearing mineral values, by froth flotation or the various other concentrating methods.
The process of this invention can be utilized 30 general to the treatment of oxygen-bearing ore materials in the presence of aliphatic alcohol esters of unsubstituted higher fatty acids, it has been found to be particularly efficient in the treatment of phosphate rock. a
In carrying out the present invention an aque- 4 ous pulp of an oxygen-bearing ore material such as for example a barite-silica ore, may be mixed with a small quantity of fuel oil, pine oil, caustic soda, an ester of an aliphatic alcohol and an un- It is an advantage of the present invention that the aliphatic alcohol esters of the unsubstituted higher fatty acids used need not be of a high degree of purity but may be employed in a somewhat crude formwhich is an important factor since a reagent to be commercially useful in. the concentration of? most oxygen-bearing ores must be relatively inexpensive.
' While these esters are useful. as reagents in the recovery of oxygen-bearing ore materials in general, they are particularly valuable in connection with the recovery of phosphate rock by froth flotation which represents the preferred embodiment of the present invention.
It is also an advantage of the present invention that the reagent permits the adoption of the concentration method which minimizes the consumption of reagents and produces the maximum results; For example, the coarser grades of phosphate rock, 28 mesh and larger, can be very economically concentrated by film flotation or tabling operations employing the reagent of the present invention, while the finer grades can be concentrated by froth flotation.
The invention will be further illustrated in connection with the following specific examples.
600 gram samples of Florida pebble phosphate rock in the form of deslimed classifier rake products were diluted to a pulp density of about 73% solids with tap water. Each charge of the ore was then conditioned 5 minutes with the following reagent mixture:

Aliphatic alcohol esters of fatty acids-.. Variable Each charge was then transferred to a Fagergren flotation machine and a concentrate removed by froth flotation. The concentrate was cleaned without using additional reagents. A comparative test was conducted in which.flsh oil fatty acid was used instead of an ester. The metallurgical results are given below:
