Feldspar minerals are often due to iron and greatly reduced the quality of feldspar, affecting the price of feldspar. Reduce the iron content of feldspar, improve the quality of feldspar, increase economic efficiency is the first issue in the face of feldspar mining, processing enterprises.
Especially in recent years, early high quality low iron feldspar resources were almost depleted, plus the need of enterprise quality feldspar feldspar have become increasingly demanding, the preparation of low iron feldspar to highlight the value of using the existing high iron content of feldspar resources, it is imperative to.
In particular, it is worth mentioning that some feldspar ore source of high iron content and the quality of a large discount. Want to do a good job in addition to iron feldspar have the following questions must be clear: the occurrence of 1 feldspar iron: iron in feldspar often magnetite, hematite, biotite, muscovite, chlorite, ilmenite and other forms exist, the above existence form has magnetic properties, completely can reduce the content of iron by magnetic separation this low cost way.
Of course, the iron will also be in the form of non - magnetic characteristics in the ore, such as pyrite, iron ore. 2 the particle size of magnetic particles and ore. If (200 mesh sieve) with coarse, dry iron will achieve good results, roller dry magnetic separator is very important, both to high field strength, but also the high gradient magnetic separator, magnetic separation effect of the difference is very big, and dry type strong magnetic separator of a German company to introduce the technology of feldspar powder in addition, the effect of iron reduction of iron feldspar powder significantly more than the domestic equipment; 200 mesh powder is best by wet process in addition to iron, not only pollution is small, but the effect is good, the effect mainly depends on the intensity and gradient, the domestic equipment of similar appearance, but the technical level is different, the effect of different concentration.
