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.
mixtures can occur naturally, such as in sand deposits, or can be obtained from flotation of mined and crushed rock. 11.27.2 Process Description 1-2 Conventional open-pit mining methods including removal of overburden, drilling and blasting, loading, and transport by trucks are used to mine ores containing feldspar. A froth flotation process is ...
1. In the case of the flotation of iron oxide from glass quartz sand by an anionic collector in the presence of soda and liquid glass the mass content of Fe 2 O 3 in the sand decreases from 0.34 to 0.053%. 2. A flotation method distinguished by the fact that a mixture of air with hot (> 100°C) water vapor is used as the gas phase was developed.
