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 service.
