Embodiment 1

[0028] In the present embodiment, a kind of potash feldspar iron removal refining method comprises the following steps:

[0029] (1) Ore washing treatment: After the potassium feldspar raw ore is crushed once to a particle size of 1cm, the ore washing treatment is carried out through a spiral chute, and the sludge is removed and then dehydrated;

[0030] (2) Primary magnetic separation treatment: the potassium feldspar after the above-mentioned ore washing is passed through the first electromagnetic mineral processing equipment, and magnetic separation is carried out at a magnetic field strength of 0.5T and a rotating speed of 80r / min;

[0031] (3) One-time ball milling treatment: the above-mentioned potassium feldspar processed through one magnetic separation process is carried out by ball milling through the first ball mill until the particle size is 30 meshes, so as to obtain potassium feldspar particles;

[0032] (4) One-time high-pressure treatment: the above-mentioned po...

Abstract

The invention belongs to the technical field of comprehensive utilization of mineral resources and in particular relates to an iron removal and concentration method for potassium feldspar. The iron removal and concentration method for the potassium feldspar comprises the following steps: (1) carrying out mineral washing treatment: carrying out the mineral washing treatment through a spiral chute;(2) carrying out first-time magnetic separation treatment; (3) carrying out first-time ball milling treatment; (4) carrying out first-time high-pressure treatment; (5) carrying out second-time magnetic separation treatment; (6) carrying out second-time ball milling treatment; (7) carrying out second-time high-pressure treatment; (8) carrying out third-time magnetic separation treatment; and (9) drying. The iron removal and concentration method for the potassium feldspar, provided by the invention, various iron removal technologies are combined and iron impurities in the potassium feldspar canbe effectively removed; and the whiteness of the concentrated potassium feldspar is high.

Description

【Technical field】 [0001] The invention relates to the technical field of comprehensive utilization of mineral resources, in particular to a method for removing iron and concentrating potassium feldspar. 【Background technique】 [0002] Feldspar is an important industrial mineral, mainly used as a raw material for the production of ceramics and glass. The consumption of feldspar in the glass industry accounts for about 50-60% of the total consumption of feldspar, and the consumption of feldspar in the ceramic industry accounts for about 30% of the total consumption of feldspar. In addition, potassium feldspar is also used in chemical industry, grinding Abrasive, glass fiber, welding rod production and other industries. In the production of white glass, the iron in the raw material will have a bad influence on the light transmittance and color of the glass; in the production of ceramics, iron is easy to cause black spots, melting scars and melting holes on the surface of the p...
