Application of cyclone in fluorite ore dressing

Hydro Cyclone is suitable for processing various types of pulp. Whether it is coarse or fine slurry, it can be effectively classified by cyclone 1. Grinding and classification In the fluorite ore dressing process, grinding is an important link. Due to the different embedded particle sizes of fluorite and gangue minerals, it is necessary to separate the monomers through grinding. The cyclone plays a key role in the classification process after grinding. Through the classification of the cyclone, the slurry after grinding can be divided into coarse particles and fine particles. The coarse particles return to the mill for further grinding, and the fine particles enter the next beneficiation process. This not only improves the grinding efficiency, but also ensures the smooth progress of the subsequent beneficiation process. 2. Pretreatment before flotation In the flotation process of fluorite ore, the particle size distribution of the slurry has an important influence on the flotation eff

The equipment for tin ore beneficiation

In general, the beneficiation of tin ore must first be screened to screen out large pieces of waste rock to improve the efficiency of the subsequent beneficiation process. If the mud content is high, washing is required. Therefore, the screening process usually uses a multi-purpose drum washing machine, which has both the functions of washing and screening. It is very common in the field of tin ore and gold ore washing. After washing and screening, the ore sand can enter the gravity separation process for rough separation. The gravity separation process usually uses a jig as the core gravity separation equipment. The jig for sand tin ore selection has multiple advantages such as high ore separation efficiency, good ore separation effect, high recovery rate, and low production cost. It is also the most energy-saving and environmentally friendly gravity separation equipment. The jig plays an irreplaceable role in the beneficiation of sand tin ore. Due to different types of tin ore, some

Concrete requirements for stone powder content in sand

Stone powder refers to particles less than 75μm in artificial sand and mixed sand. Most of the stone powder in artificial sand is fine particles of broken parent rock. Unlike mud in natural sand, their role in concrete is also very different. On the one hand, high stone powder content increases the specific surface area of ​​sand and increases water consumption; on the other hand, the ball effect produced by fine spherical particles will improve the workability of concrete. Therefore, stone powder in artificial sand cannot be regarded as a harmful substance. The comprehensive impact of stone powder content on artificial sand has been proved by decades of experiments: Guizhou Province began to study the use of artificial sand in the 1970s. When the stone powder content in artificial sand is 0-30%, it has little effect on the performance of concrete, has no effect on the compressive and tensile strength of medium and low-grade concrete, and has little effect on the strength of C50 grade

Feldspar desliming and washing machine supplier

For feldspar ore produced from feldspathic placer or weathered granite, the ore washing method can be used to remove impurities such as clay, mica, fine mud, etc. The Fe2O3 content of the washed feldspar ore is reduced, and the potassium and Sodium content is increased. The principle of mineral washing is that clay, mica and fine mud have small particle size and small specific gravity, so they settle slowly and can be separated from coarse-grained feldspar under the action of water flow. Ore washing equipment generally uses a washing tank or a vibrating screen. Mining sites generally use washing tanks, and mineral processing plants generally use vibrating screens. Currently, many feldspar ores use this method for impurity removal and purification. The primary slime in the feldspar mine and the secondary slime produced during the mining process will affect its mineral processing effect, so it must be removed in advance before mineral processing. The process of removing slime is called
