Tungsten ore is an important metal mineral resource widely used in aviation, aerospace, military, electronics and other fields. Tungsten ore beneficiation is the process of separating useful minerals and impurities from tungsten ore, and is one of the important links in tungsten ore mining. This article will introduce the basic process and operating steps of tungsten ore beneficiation.
1、 Basic process of tungsten ore beneficiation
1. Rough selection
Rough selection is the initial crushing of tungsten ore separated from the raw ore, followed by rough selection to separate useful minerals and impurities from the tungsten ore. Roughing mainly adopts two methods: gravity separation and flotation.
Gravity separation is the use of gravity to separate useful minerals and impurities from tungsten ore. The density of tungsten minerals in tungsten ore is relatively high and can be separated by gravity separation. Gravity separation mainly adopts two methods: heavy medium beneficiation and centrifugal beneficiation.
flotation utilizes the affinity difference between minerals and bubbles to separate useful minerals and impurities. Flotation mainly adopts two methods: air flotation and oil flotation.
2. Scanning selection
Scanning is the further separation of tungsten ore after rough selection, which separates useful minerals and impurities from the tungsten ore. Scanning mainly adopts two methods: flotation and magnetic separation.
Flotation is the separation of useful minerals and impurities from tungsten ore through the action of bubbles. Flotation mainly adopts two methods: air flotation and oil flotation.
Magnetic separation is the use of magnetic differences in minerals to separate useful minerals and impurities. Magnetic separation mainly adopts two methods: high intensity magnetic separation and low intensity magnetic separation.
3. Selection
Selection is the further separation of the scanned tungsten ore, which separates useful minerals and impurities from the tungsten ore. The selection mainly adopts two methods: flotation and gravity separation.
Flotation is the separation of useful minerals and impurities from tungsten ore through the action of bubbles. Flotation mainly adopts two methods: air flotation and oil flotation.
Gravity separation is the use of gravity to separate useful minerals and impurities from tungsten ore. The density of tungsten minerals in tungsten ore is relatively high and can be separated by gravity separation. Gravity separation mainly adopts two methods: heavy medium beneficiation and centrifugal beneficiation.
2、 Operating steps for tungsten ore beneficiation
1. Steps for rough selection
(1) Preliminary crushing of the raw ore with a crushing particle size of 30-50mm.
(2) Perform gravity or flotation to separate useful minerals and impurities from tungsten ore.
(3) Perform intermediate sorting on the separated useful minerals to separate minerals of different densities.
2. Scanning operation steps
(1) Further crush the roughly selected tungsten ore with a particle size of 10-30mm.
(2) Perform flotation or magnetic separation to further separate useful minerals and impurities from tungsten ore.
(3) Perform intermediate sorting on the separated useful minerals to separate minerals of different densities.
3. Selected operation steps
(1) Further crush the scanned tungsten ore with a particle size of 5-10mm.
(2) Perform flotation or gravity separation to further separate useful minerals and impurities from tungsten ore.
(3) Select the useful minerals separated, remove impurities from the minerals, and obtain high-purity tungsten minerals.
3、 Summary
Tungsten ore beneficiation is the process of separating useful minerals and impurities from tungsten ore, and is one of the important links in tungsten ore mining. The basic process of tungsten ore beneficiation includes three stages: roughing, sweeping, and beneficiation, each stage using different beneficiation methods for mineral separation. The operational steps of tungsten ore beneficiation include ore crushing, beneficiation, and intermediate separation. Through the process of tungsten ore beneficiation, high-purity tungsten minerals can be obtained, providing important raw materials for the application of tungsten ore.
