Problems solved by technology

Potassium feldspar resources are abundant in my country, but there are not many high-quality ores. Most potassium feldspar mines need iron removal, purification and whiteness improvement. In particular, the pollution brought by the removal of impurities to the environment makes the removal and separation of ores more difficult.
For example, Chinese patent 201610285488.6 discloses a method for removing impurities and whitening potassium feldspar. High-grade potassium feldspar sand powder with high whiteness is obtained by hydrothermal pickling with sulfuric acid; Serious pollution, and the waste water treatment cost is high, which greatly increases the production cost of potassium feldspar powder

Embodiment Construction

[0038] The specific implementation of the invention will be further described below in conjunction with the accompanying drawings.

[0039] Such as figure 1 Shown, a kind of potassium feldspar powder production preparation method comprises the following processing steps:

[0040] 1. Ore washing treatment, after mining, the raw potassium feldspar ore is crushed and washed through a spiral chute to remove the sludge in the raw ore, and finally dehydrated for use.

[0041] 2. Preliminary screening treatment, the drained raw ore is sent to the ore color sorter, and the ore color sorter screens to obtain raw ore with a whiteness greater than 15%; specifically, the ore color sorter screens in the preliminary screening The raw ore with whiteness not less than 25% is obtained.

[0042] 3. Crushing treatment, the raw ore obtained by screening is crushed, and the ore crushed to a particle size of less than 1cm is obtained.

[0043] 4. A ball milling process, the ore is sent into the ...

Abstract

The invention discloses a potassium feldspar powder production and preparation method, and belongs to machining technologies of potassium feldspar powder. The method comprises the steps of ore washing treatment, preliminary screening treatment, crushing treatment, primary ball milling treatment, primary screening treatment, primary cyclone treatment, primary magnetic separation treatment, secondary ball milling treatment, secondary screening treatment, secondary cyclone treatment, secondary magnetic separation treatment, third cyclone treatment and thickening and dehydration treatment, and potassium feldspar mineral powder with the moisture content being lower than 16% and the brightness being higher than 60% is obtained.

Description

technical field [0001] The invention relates to a processing technology of potassium feldspar powder, in particular to a production and preparation method of potassium feldspar powder. Background technique [0002] Potassium feldspar is a kind of feldspar mineral, which is a framework silicate containing potassium, which is KAlSi 3 o 8 The general term for the three homogeneous multi-phase variants of feldspar, orthoclase and feldspar. Potassium feldspar has the characteristics of low melting point, long melting interval and high viscosity of molten liquid, and the glassy substance melted at high temperature has the characteristics of transparency, and is widely used in the fields of glass and ceramic industries. [0003] Potassium feldspar powder minerals are not only used as raw materials for the glass industry (accounting for about 50-60% of the total consumption), but also for 30% in the ceramic industry, and the rest are used in chemical industry, glass flux, ceramic ...
