1. Ore nature: The mining area is a gently denuded hilly area. The sand gold ore body belongs to the Quaternary alluvial sand deposit and is located in the Baishantun ditch. CCP placer minerals main magnet ore, 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.
2, the process: the use of two-stage jigging, remote bed selection. Direct production of gross gold and heavy sand. The process flow is shown in Figure 1.

The Hani River Gold Mine adopts machine mining and transportation, and concentrates on the construction of large-scale machine selection plant. The process is relatively perfect and the recovery rate of gold is high. It can be used for sand gold mines where water sources are difficult and where conditions are concentrated. The process indicators are shown in Table 1, and the main equipment is shown in Table 2.
