Effects of operational parameters of spiral concentrator on mica–feldspar separation Author： Gulsoy O. Y. Kademli M. Publisher： Maney Publishing ISSN： 0371-9553 Source： Mineral …
It was observed that in a spiral concentrator mica could be separated from feldspar owing to its laminar morphology. Accordingly, it was found that particle size and solid contents had significant effect on the separation. Best results were obtained with feed solid content of 15% by weight for the particle size fraction of −212 + 74 μm.

In the spiral concentrator, the major parts of the water in the feed were accumulated at the outside of the separation surface, carrying most of the flaky mica with it. The feldspar particles were moved predominantly to the inner part of the surface, forming a natural gap between the concentrate and the tailing streams.
Chromite beneficiation plants generate large amount of tailings with significant amounts of ultrafine chromite minerals. In the present investigation, Box−Behnken experimental design was used to model the effects of feed rate, feed pulp density and splitter position on the performance of a spiral concentrator for separating the ultrafine chromite values from the plant tailings. …

In comparison, the gravity table, HG8 spiral, CT spiral and Humphrey spirals yielded concentrates with 92.2%, 92.9%, 93.6%, and 98.2% THM, respectively, from a feed sample containing 4.72% THM.
Mica Uses. The principal use of ground mica is in gypsum wallboard joint compound, where it acts as a filler and extender, provides a smoother consistency, improves workability, and prevents cracking. In the paint industry, ground mica is used as a pigment extender that also facilitates suspension due to its light weight and platy morphology.
