Froth Flotation Of Feldspar

Feldspar Beneficiation & Flotation Process

Feldspar Flotation All flotation is carried out in acid circuits, either with sulphuric acid or hydrofluoric acid both of which are highly corrosive to metal parts. For this reason it is necessary to use flotation machines with wooden tanks, partitions, hoods and standpipes, and molded stone impellers and wearing plates.

Froth flotation of mixed feldspar

Froth flotation was used to separate feldspar from micas, iron-bearing minerals and quartz using cationic, anionic and acid flotation respectively. Evaluation of the separation was done by using data from yield of feldspar, X-ray fluorescence and cone firing test.

Froth Floatation - Purdue University

Froth Flotation. After being rinsed, if the sample contains feldspar and mica it will be frothed. To efficiently separate feldspar and mica from quartz, we have developed a procedure that makes feldspar and mica hydrophobic and the quartz becomes hydrophilic. By adding a carbonated solution to the sample, we can separate up to 95% of the feldspar.

Froth Flotation The materials used for Froth Floation: the carbonator, large aluminum bowl and bottles of Lauryl Amine and Glacial acetic acid. After being rinsed, if the sample contains feldspar and mica it …

11.27 Feldspar Processing

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-circuit flotation process.

Selective flotation separation of spodumene from feldspar ...

The selectivity in flotation separation of spodumene from other pegmatic aluminosilicates such as feldspar and mica, using a single fatty acid anionic collector, is found to be very difficult. It is attributed to the same surface Al site for interaction with fatty acid.

Processing Spodumene by Froth Flotation for Lithium Extraction

Complete removal of iron minerals along with some remaining feldspar is accomplished in a froth product which is small and is discarded. Although not indicated on the flowsheet, the final cleaner gangue froth, which contains feldspar and mica, can be processed in an acid circuit for the recovery of mica first.
