Problems solved by technology

[0005] Although some reports have been made on the flotation separation of potassium albite feldspar in the literature, these reports are all based on increasing the concentration of K in the concentrate. 2 O grade purposes, for Na 2 The concentrate grade or yield of O is not considered, resulting in Na 2 Concentrate grades and yields of O have been low

Embodiment Construction

[0019] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments. This embodiment is only to illustrate the present invention more clearly, rather than limit the present invention.

[0020] Below adopt mineral processing technology provided by the present invention (attachment figure 1 ) to beneficiate the following raw ore:

[0021] A low-grade potassium-sodium feldspar mine in Guangxi, my country, the ore mainly contains albite, potassium feldspar, mica minerals, quartz, calcite, and a small amount of hematite. Analysis of main elements: K 2 O, 5.37; Na 2 O, 4.45; Fe 2 o 3 , 1.25; TiO, 0.34.

[0022] The specific process steps are:

[0023] (1) Coarse grinding: Crushing and grinding the raw ore of potassium albite feldspar, and controlling the particle size to -0.045, accounting for 70%;

[0024] (2) Magnetic separation and impurity removal: use a magnetic separator for magnetic separation, the flow r...

Abstract

The invention provides a method for separating potassium feldspar and soda feldspar from potassium-soda feldspar ore and belongs to the technical field of mineral separation. The method includes procedures of double grinding of ore, double magnetic-separation of ore, double flotation of concentrates and the like, is a simple and low-cost floatation separating process, causes no environmental pollution, has the effects of improving quality and recovery rate of concentrates of potassium feldspar and soda feldspar remarkably, also has effects of high impurity removal speed and high finished-product recovery rate, and is suitable for industrial application.

Description

technical field [0001] The invention belongs to the technical field of mineral processing and relates to a method for separating potassium feldspar and albite from potassium albite ore. Background technique [0002] Feldspar is a group of minerals composed of aluminum silicates of potassium, sodium, calcium and barium. It is the most common ore in the earth's crust, accounting for 60%. It can appear in igneous rocks, metamorphic rocks, and sedimentary rocks. The melting point of feldspar is between 1100-1300 ℃, and it has good chemical stability. It has a melting effect when eutectic with quartz and aluminosilicate. It is often used as an auxiliary agent for making glass and ceramic blank glazes, and can reduce Firing temperature; In addition, the formation of feldspar glass body can also improve the light transmittance of the green body. [0003] Most feldspar deposits can be divided into albite deposits, potassium feldspar deposits and mixed potassium albite deposits. Th...
