Feldspars are aluminosilicate minerals with varying amounts of
potassium, sodium and calcium in a solid solution series. It is the
most abundant mineral group, constituting ~60% of the Earth’s
crust. The most common economic concentrations occur in pegmatites.
Most commercial varieties are alkali feldspars, with composition
between sodium and potassium end members, or at the sodic end of
the plagioclase (sodium–calcium) group. The principal minerals are:
- Potassium feldspar
- ‘K-spar’: microcline or orthoclase, KAlSi3O8
- Sodium feldspar or ‘Na-spar’: albite, NaAlSi3O8
- Oligoclase, (Na,Ca)AlSi3O8
Feldspar is an important ingredient in glassmaking. In ceramics it
acts as a flux which imparts the vitreous lustre to chinaware,
sanitaryware and ceramic tiles. It is used in glazes and enamels,
and is an important mineral filler in paints, plastics, sealants
and adhesives.
Feldspars Crushing & Grinding
Large particle size of feldspar ore firstly should be crushed by
jaw crusher to qualified particle size, thus to guarantee the
grinding quality and protect ball mill.
Ball mill is applied into the second stage – grinding, Hengyang has
wet grate ball mill and wet grate overflow ball mill which can
perfectly grind feldspar ore into qualified particle size.
Feldspars Flotation Separation
With experience in Feldspar flotation separation, flotation cell is
the main mining machines in this part, the slurry dealt with
agential through milling and inflating can make certain particles
of it selectively attaches to the bubbles to achieve mineral
separation.
Besides flotation machines, other mining machines also will be used
in the stages, if you want to know more, just click the online
