Tungsten ore is divided into wolframite and scheelite according to its properties. Most tungsten The ore deposits are all low-grade ore deposits. Different types of ores use different beneficiation methods and process equipment for separation. The main beneficiation methods of wolframite and scheelite are described below:
, wolframite ore Mineral processing and related mineral processing equipment
, pre-enrichment
Most wolframite ores have a high dilution rate, often above %, so the coarse and poor waste rocks should be discarded in advance as much as possible before gravity separation. important. my country's wolframite concentrators usually use pre-hand selection to discard a large amount of waste rock. There are also examples of pre-enrichment of wolframite ore using heavy medium mineral processing method and photoelectric sorting method. The mineral processing equipment used is heavy medium mineral concentrator, photoelectric sorting machine, etc.
Gravity beneficiation
The beneficiation of wolframite ore is mainly based on the gravity beneficiation method. Tungsten ore has high density, and the gravity separation method can effectively separate it from many mineral particles with a density less than . Especially in quartz vein deposits (most tungsten ores in my country belong to this category) wolframite has a large crystal size, so it is more suitable to recover it early by gravity separation in the case of coarse particles. Jig and shaker are the most commonly used equipment in gravity separation operations. Jig plays an important role in selecting coarse and medium-grained wolframite ore. The ore is often screened and classified before selection. Perform jigging. In order to reduce the sludge of tungsten ore, a jig is added to the grinding cycle so that the dissociated tungsten ore can be recovered as early as possible. The tungsten concentrate collected by the jig generally accounts for more than % of the total recovery rate of the entire plant. The shaking table is suitable for sorting fine-grained ores. Its advantage is that the enrichment ratio is very good. In order to obtain a good sorting effect, it is necessary to strictly classify the materials before sorting. Ore concentrators usually use hydraulic classifiers for classification. .
Fine mud treatment
Black tungsten fine mud flotation, many studies have been conducted in China, and new technologies such as branched series flow flotation, fractional speed selection, thick slurry aeration and stirring are recommended in the separation process. , can save flotation chemicals and improve flotation effect. In terms of magnetic separation, the newly developed wet-type strong magnetic separator in recent years has a remarkable effect in selecting black tungsten fine mud.
, the beneficiation of scheelite and related beneficiation equipment. According to the dissipation characteristics of the ore, the beneficiation of scheelite can be combined with gravity separation and flotation, or a single flotation method. Some scheelite beneficiation plants also perform pre-enrichment. set. Scheelite has good floatability, and the flotation process is complicated by the presence of calcium-containing gangue minerals with similar properties in the ore, such as calcite, fluorite, apatite, etc. In order to improve the selectivity of the flotation process, adding multivalent metal salts to water glass species can significantly improve the flotation effect of scheelite.
