The tungsten ore beneficiation production line is a production line for the ore dressing and purification of tungsten ore. The configuration of the tungsten ore beneficiation production line is mainly determined by the nature of the tungsten ore. Under normal circumstances, the tungsten ore can be divided into scheelite and black tungsten ore. There are certain differences, so the tungsten ore beneficiation production line is also divided into different types. The scheelite ore dressing production line is mainly a flotation production line. The black tungsten ore beneficiation production line is mainly a re-election line, but due to the different ore properties, for coarse-grained inlays. The sulphur ore beneficiation and re-election production line are also completely feasible. Below we will take a look at the beneficiation production process of scheelite and wolframite for reference by relevant parties!
1. White tungsten ore dressing process
The scheelite is naturally floatable, mostly fine-grained, and the content is low. Therefore, the most commonly used scheelite ore dressing production line is a flotation production line, which recovers white tungsten from low-grade scheelite to achieve the purpose of beneficiation and purification. The scheelite flotation production line is mainly composed of crusher , ball mill , classifier, mixing tank, flotation machine, concentrator, filter press and other equipment. The ore dressing process is complex, the equipment investment is huge, and the production cost is also high, but the ore dressing The indicator is better.
The scheelite re-election line is a beneficiation production line designed for the coarse-grained scheelite. It has a poor effect on fine-grained scheelite. The re-election of scheelite mainly consists of crusher and vibration. Screening, rod mill, jig, dewatering screen, etc. The re-election line is sorted according to the difference in specific gravity between scheelite and gangue. It has simple beneficiation process, low equipment investment, low production cost and beneficiation efficiency. Higher characteristics, but its ore dressing index is lower than the flotation production line.
2. Black tungsten ore beneficiation process
The ore dressing of the black tungsten ore is mainly based on re-election. Since the black tungsten ore has a certain magnetic permeability, there are cases in which the black-tungsten ore is recovered by strong magnetic separation, but the most important method is the re-election method. The black tungsten ore beneficiation production line mainly consists of crusher, rod mill, jig, dewatering screen, etc. It is also gravity sorting based on the difference in specific gravity between the black tungsten ore and the gangue, due to the scheelite and the wolframite. Crystals are characterized by brittleness and brittleness. Therefore, it is recommended that the crushing process use crushing equipment with less pulverization, such as rod mills and roller crushers.
Quick target acquisition: Red dot sights allow for faster target acquisition compared to traditional iron sights. The illuminated reticle makes it easier to focus on the target and align the sight.
Parallax-free: Most red dot sights are designed to be parallax-free, meaning the point of aim remains consistent regardless of the shooter's eye position. This feature helps improve accuracy and reduces aiming errors.
Unlimited eye relief: Red dot sights provide unlimited eye relief, which means there is no specific distance the shooter's eye must be from the optic. This allows for more flexibility in shooting positions and makes it easier to use the sight in dynamic situations.
Improved low-light performance: The illuminated reticle in a Red Dot Sight can be adjusted for brightness, making it easier to aim in low-light conditions compared to iron sights.
Versatility: Red dot sights can be used with a variety of firearms, including AR-style rifles, shotguns, and handguns. This makes them versatile accessories for different shooting applications.
