Embodiment 1

[0048] Experiments were carried out on the Laiyang feldspar mine in Shandong, the chemical composition of the raw ore: K 2 O: 8.24%, Na 2 O: 2.50%, Fe 2 o 3 : 0.30%, mica: 1.2%, and build a feldspar processing plant with a daily processing capacity of 2,500 tons.

[0049] Firstly, the raw ore is ground through a ball mill; the ground feldspar ore is classified and deslimed with an improved hydraulic classifier to obtain feldspar ore with a grinding particle size of -200 mesh accounting for 68%; the classified feldspar ore is Weak magnetic separation with a magnetic field strength of 1000Oe is carried out through a weak magnetic separator to separate the strong magnetic substances and the feldspar coarse concentrate into the strong magnetic separation; then the feldspar coarse concentrate obtained after the weak magnetic separation is passed through the strong magnetic separator Carry out strong magnetic separation with a magnetic field strength of 8000Oe, separate and obtai...

Embodiment 9

[0056] Conducted experiments on Hengyang feldspar mine in Hunan, and built a feldspar ore dressing plant with a daily processing capacity of 1,200 tons. The operation effect is very good. The chemical composition of the raw ore: K 2 O: 6.98%, Na 2 O: 3.88%, Fe 2 o 3 : 0.39% Mica: 1.8%, Tourmaline: 1.2%.

[0057] Firstly, the raw ore is ground through a ball mill; the ground feldspar is classified and deslimed with an improved hydraulic classifier to obtain a feldspar with a grinding fineness of -200 mesh accounting for 72%; the classified feldspar The ore is subjected to weak magnetic separation with a magnetic field strength of 1500Oe through a weak magnetic separator to separate the strong magnetic material and the feldspar coarse concentrate that is put into the strong magnetic separation; then the feldspar coarse concentrate obtained after the weak magnetic separation is passed through the strong magnetic separation The machine carries out strong magnetic separation wit...

Embodiment 19

[0064] Experiments were carried out on Albanian feldspar mines, the chemical composition of the raw ore: K 2 O: 4.37%, Na 2 O:, 3.38%, Fe 2 o 3 : 0.48%, Mica: 3.4%.

[0065] Firstly, the raw ore is ground through a ball mill; the ground feldspar is classified and deslimed with an improved hydraulic classifier to obtain feldspar with a grinding fineness of -200 mesh accounting for 70%; the classified feldspar The ore is subjected to weak magnetic separation with a magnetic field strength of 3000Oe through a weak magnetic separator to separate the strong magnetic material and the feldspar coarse concentrate into the strong magnetic separation; then the feldspar coarse concentrate obtained after the weak magnetic separation is passed through the strong magnetic separation The machine carries out strong magnetic separation with a magnetic field strength of 12000Oe, and separates weak magnetic substances and feldspar coarse concentrate into flotation; the feldspar coarse concent...

Abstract

The invention relates to a method for separating and extracting feldspar ore with complex impurity components, which comprises the following steps of: 1) performing ball milling on the feldspar ore with complex impurity components through a ball mill; 2) performing classification and de-sliming on the milled feldspar ore by using an improved hydraulic classifier; 3) performing low-intensity magnetic separation on the classified feldspar ore through a low-intensity magnetic separator to obtain high-intensity magnetic substances and rough feldspar concentrate for high-intensity magnetic separation; 4) performing high-intensity magnetic separation on the rough feldspar concentrate obtained by the low-intensity magnetic separation through a high-intensity magnetic separator to obtain low-intensity magnetic substances and rough feldspar concentrate for flotation; and 5) performing size mixing and segmentation on the rough feldspar concentrate obtained by the high-intensity magnetic separation, adding a flotation agent, and performing reverse flotation, impurity removal and dehydration through a flotation machine to remove impurities and obtain fine feldspar and quartz mixed powder and flotation water.

Description

technical field [0001] The invention relates to a method for separating and extracting feldspar ore, in particular to a method for separating and extracting feldspar ore with complex impurity components, and belongs to the fields of metallurgy and chemical industry. Background technique [0002] According to different types of feldspar deposits and ore properties, different beneficiation methods need to be adopted. With the different deposits of feldspar, the ore properties and associated impurities may also be different. At present, the following mineral processing principles are generally adopted in domestic and foreign dressing plants: (1) High-quality feldspar produced from pegmatite: hand selection→ Crushing → ore grinding or water milling → classification; (2) Feldspar in weathered granite: crushing → ore grinding → classification → flotation; (3) Feldspar in fine crystal rock, generally containing mica, sometimes iron: crushing →Grinding→Sieving→Magnetic separation; ...
