Sekulic et al. reported a comparative study of feldspar flotation using two commercial collectors, AERO 3030C (Cytec Industries Inc.) and Flotigam DAT (Clariant AG). Both the two collectors have good ability to float feldspar from a mixture of other gangue minerals, but recoveries concerning AERO 3030C are more than that of Flotigam DAT ...
the feldspar surface while depositing fluoride ions [15]. As a result of this mechanism, feldspar tends to be effectively depressed in the presence of collectors. Quartz could be easily floated, without using collectors, with HF solution and frother Brij C58 [19]. Selective flotation can be performed on feldspar from other impurities in the ...
The published flow sheets, in most cases, do avoid exact figures, except thoseon products and production. FLOTATION OF FELDSPARS 73 The Kona Feldspar Plant in North Carolina, for instance, produces glass spar as well as pottery spar (LUTJEN, 1953). ... do not offer much useful information for feldspar flotation on a laboratory level. Exact ...
We achieved separation of quartz from feldspar with a newly built flotation cell for our feldspar-rich samples from the Pamir, Central Asia. Introducing flotation to the sample preparation procedure ensures quartz enrichment and mitigates problems related to contaminations with other mineral phases in 10 Be and 26 Al cosmogenic nuclide dating ...
In this study, the effects of ultrasound on removal of impurities from raw feldspar were investigated by testing with a newly developed flotation cell with various frequency and power intensities prior to multistage feldspar flotation. Particularly, the quality of feldspar concentrates, the volume of removed slimes and the content of impurities were taken into …
Feldspar flotation flow sheet. Figure 5 shows the floating feldspar from rougher cell flows to the 3 units of attrition scrubber tank and spiral classifier. During the process, NANSA which is the reagent for cleaning the ore surface will be added, the overflow feldspar from the last Spiral Classifier will flow to fine feldspar pool and underflow
In this study, feldspar ore was successfully enriched using a two-stage process. Initially, dry magnetic separation was employed to remove iron oxide, followed by cationic flotation to eliminate gangue minerals containing free silica. A feed sample with a size fraction of (− 0.25 + 0.053) mm, pre-treated by attrition scrubbing and dry high-intensity magnetic separation …
In feldspar flotation, the minerals causing slime formation have similar mineralogical properties to other minerals trying to be floated during the mica and and heavy mineral removal flotation stage. This causes unsuccesful selective separation and also excessive reagent consumption [19,27,30–32]. ... Experimental process flow sheet. Minerals ...
As a result of these tests, air volume flow was also calculated for a pilot scale free jet flotation unit. The results showed that an effective separation of TiO 2 and Fe 2 O 3 bearing minerals by ...
