K-feldspar Description

K-feldspar (KAlSi3O8), usually referred to and orthoclase are monoclinic system, usually red meat, white or gray. The density 2.54-2.57g/cm3, specific gravity of 2.56 to 2.59g/cm3 Hardness 6, the theoretical composition SiO2 64.7% Al2O3 18.4%, 16.9% K2O. It has a low melting point (1150 ± 20 ℃), melting long interval, high melt viscosity characteristics, widely used in the the blank ceramic, ceramic glazes, glass, porcelain, and abrasive materials and other industrial sectors and the system potash.

K-feldspar mine high potassium content, the most widely distributed, and the largest reserves of non-water-soluble potassium resources. K-feldspar ore source of 60, their average potassium content of about 11.63%, and its reserves of about 7.914 billion t converted into hydroxide reserves of approximately 920 million tons, according to the average content. Anhui, Inner Mongolia, Xinjiang, Sichuan, Shanxi Province, the K-feldspar is relatively concentrated, abundant, and the advantage of local non-metallic mineral resources.

Potassium feldspar ore dressing process

Domestic K-feldspar is rich in resources, but excessive iron content, K-feldspar in addition to iron is purified. Iron is the magnetic objects, while feldspar non-magnetic material in a magnetic field, the two are very easily separated.

The potassium feldspar raw single-handedly selected a broken one grinding a finished grading a dehydration process applies to low iron content, good quality raw material. Pre-crusher for coarse crushing and fine crushing in order to prevent the contamination of the processing of iron K-feldspar, so choose grinding equipment easy turbines, pebble mill or porcelain ball mill, ultrafine laminated since the mill etc. as grinding equipment, spiral classifier ensure product granularity.

The advantages of potassium feldspar ore dressing process

Simple process,less investment, the disadvantage of this process is that the the product iron content indicators difficult to meet the requirements of high-quality ceramic products. In order to overcome the shortcomings of the process, increasing the magnetic separation process, proved choose wet high gradient magnetic separator effect in addition to iron,iron removal efficiency of 70% -90%.
