The selection of a reasonable process is mainly based on the physical properties and mineral composition of the ore and natural gold . In order to obtain better sorting indicators and economic effects in production, the determination of the testing process of the beneficiation process should be considered according to the following aspects: 1. Mineral composition and physical properties of the ore; 2. Size of the deposit; 3. Production Size. Different mineral processing equipment and processes can be selected in different situations. In the optional test, the test of the beneficiation process should be carried out by comparing two or more schemes for selection by the production and design departments. Anticorrosive and Antifouling Paint/Coating Additives Fluorocarbon material is a functional carbon-based fluorine material with special performance. Fluorocarbon material products have extremely low surface energy, excellent chemical thermal stability, and excellent water repellency, and are suitable for special anti-corrosion and anti-fouling coatings.

     For example, the Hanihe gold deposit in Inner Mongolia is a gently denuded hilly area, and the gold deposit is a Quaternary alluvial deposit. Placer symbiotic main magnetic iron ore minerals, titanium, iron, followed rutile, zircon, monazite, limonite. Gold exists in the state of natural gold, and the particle size is relatively coarse, generally 0.1-1.0 mm, less than 0.074 mm. The grain-grade gold is very small, and does not contain colloidal clay , which is a sand gold mine that is easy to wash.
     The design scale of the mining plant is 500 tons/day. It is equipped with two-stage jigging and shaker selection, which directly produces gross gold and heavy sand. The process flow is shown in the figure below. The screening operation adopts SZZ1250×2500 vibrating screen, the general jigging is 1200×2000×3600 trapezoidal jig, the second stage jigging uses 2 sets of 300×450 jumper, and the selected equipment is 3 sets of 6-S shaker. . The Hani River Gold Mine adopts machine mining and transportation, and concentrates on the construction of large-scale machine selection plant. The process flow is relatively perfect, and the recovery rate of gold is up to 93%. It can be used for sand gold mines where water sources are difficult and where conditions are concentrated.
