In the flotation process of barite, there is a range of maximum floatability pH value, and its maximum floatability pH range is about neutral pH, which increases with the increase of oleic acid dosage within a certain range. 4. Times of Concentration In actual production, there are certain requirements for the concentration times.
In barite flotation, sodium oleate is widely used as a collector in a highly alkaline pulp, ... In this process, the depression of the hematite surface is an essential factor. Thus, the ...
All rare-earth ores contain less than 10 percent REO and must be upgraded to about 60 percent in order to be processed further. They are first ground to a powder and then separated from the other materials in the ore body by various standard processes that include magnetic and/or electrostatic separation and flotation. In the case of Mountain …
The process of flotation is of course well-known, and need not be described in detail here. Reference may be made to standard texts on the subject, such as that by A. M. Gaudin entitled Flotation, published by McGraw-Hill Book Co., New York, 1932. ... In a froth flotation of barite from its ores, wherein an aqueous suspension of comminuted ...
