Problems solved by technology

However, the above method adopts the method of segmented reverse flotation to remove impurities in the flotation process, and the number of alkaline and acidic flotation stages is 5 times. The flotation process is complicated, and the use of flotation agents increases, which increases the production cost.

Embodiment Construction

[0017] 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 to limit the present invention.

[0018] Below adopt mineral processing technology provided by the present invention (attachment figure 1 ) to beneficiate the following raw ore:

[0019] 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; CaO, 1.02.

[0020] The specific process steps are:

[0021] (1) Coarse grinding: The selected raw ore is crushed with a crusher, and the ball mill is used for grinding and controlling. The particle size of the ore is -0.045, accounting for 70%;

[0022] (2) Magnetic separation and impurity removal: use a magne...

Abstract

The invention provides a low-grade potassium sodium feldspar quarry floatation and purification process and belongs to the technical field of ore separation. The process includes double ore grinding, double magnetic separation, ore concentrate floatation and the like. The process has the advantages that quality and recycling rate of potassium sodium feldspar concentrate are increased evidently, the process is simple, low in cost, especially suitable for the field of ore separation of the low-grade potassium sodium feldspar complex and difficult in separation, high-grade potassium sodium feldspar concentrate with high recycling rate can be floated from low-grade raw ore, ore resource utilization rate is increased, and the process is significant to developing and utilizing low-grade or secondary ore resources.

Description

technical field [0001] The invention belongs to the technical field of mineral processing, and relates to a low-grade potassium albite ore flotation impurity removal process. 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] At present, the process of "grinding - desliming - magnetic separation - flotation" is generally used in the beneficiation of potassium sod...
