Since the inception of the feldspar flotation process using hydrofluoric acid by O'Meara the process has achieved a great commercial success. In the conventional flotation separation of feldspar-quartz, hydrofluoric acid is used to suppress quartz and activate feldspar, and a long chain amine salt (acetate or chloride) is used as a collector.
A froth flotation process is used for most feldspar ore beneficiation. Figure 11.27-1 shows a process flow diagram of the flotation process. The ore is crushed by primary and secondary crushers and ground by jaw crushers, cone crushers, and rod mills until it is reduced to less than 841 µm (20 mesh). Then the ore passes to a three-stage, acid ...

Apr 27, 2007· This paper reviews the application of flotation for the separation of feldspar from the other minerals with which it naturally occurs (such as quartz, clay minerals, mica, ilmenite, rutile, anatase and magnetite) as well as the separation of the individual feldspar minerals themselves. Much of the ...
Feldspar Mineral Processing. Feldspar ore is the main source of feldspar mineral concentrate or purified feldspar used in the manufacture of various grades of glass and ceramics including high-end ceramics and electronic-grade glass fibers.
The feldspar minerals and quartz were separated from each other by flotation of feldspar minerals and depression of quartz minerals. Both feldspar and quartz in amine flotation and in the absence of HF need not be floated at pH less than 4. However, in the presence of HF feldspar is floated at pH 2–3 while quartz does not float.
A separation process is provided for treating a feed material comprising silica, feldspar, and metal impurities, including at least one of mica, iron impurities, or refractory heavy minerals, to form one or more products for use in making glass. In the process, the feed material is floated in the presence of a depressant to inhibit the flotation of feldspar and thereby form a concentrate ...

The general circuit for commercial separation of feldspar consists of three sequential stages of flotation, all of which are carried out in an acid medium. Usually, before flotation, the feed is deslimed, removing any fine clay minerals present. In the first flotation stage, mica is removed with an amine collector.
Abstract Flotation is the only technique that enables the selective separation of Na and K feldspar minerals from each other. In this study, the flotation separation of Na-feldspar (albite) and K ...
