Recently, the ability to beneficiate feldspar has developed remarkably because flotation techniques proved its viability [2] [4] [5]. It is now possible to free feldspar from all kinds of gangue minerals, mica, quartz and heavy minerals in addition to separation of both K and Na feldspars from each other [2][4]. Cationic flotation of
The FLOTATION PROCESS is one of the commonest methods of extracting the valuable minerals from certain classes of ores, and it is generally more efficient as regards the recovery of the minerals than any other process applicable to the treatment of similar types of ores. The metallic contents of the minerals are recovered from the concentrates in a subsequent series of metallurgical operations ...
