Durable Polyurethane Sand Spiral Separator for Gold Mining and Ore

It adopts gravity-centrifugal synergistic separation. Based on the differences in density and particle size of various minerals, it realizes precise separation of fine-grained minerals in the fluid-dynamically optimized trough. The whole process adopts pure physical separation without any chemical reagents, which is eco-friendly and pollution-free.

It is mainly used for the separation of refractory fine-grained minerals. It can accurately capture fine minerals such as -0.45 mm, 800 mesh (0.019 mm) and -0.038 mm, and is also suitable for the recovery of conventional fine-grained tailings, perfectly making up for the technical shortcomings of traditional equipment in fine-grained separation.

Five series (F/H/M/L/X) with various specifications are available. The selection is mainly based on mineral properties, processing particle size and capacity requirements. For example, Model F13 is preferred for gold ore and tin ore; Model H8 is used for hematite concentration; Model M5 is designed for coal-fired desulfurization; and Model F13+L5 is suitable for coastal placer separation.

Higher separation efficiency for fine-grained minerals, completely solving the problems of tailings loss and resource waste; Pure physical process requiring no reagents, reducing chemical costs and being more environmentally friendly; Low energy consumption, easy operation and maintenance, and flexible combination for the whole process including roughing, cleaning and scavenging; Strong tailings discarding capacity, with up to 83% of tailings removable in the roughing stage, greatly reducing sub

The separation recovery rates are excellent for different minerals, with key indicators: Recovery rate of fine-grained gold ore: 87.11%; Zirconium/titanium recovery rates of coastal zircon-ilmenite placer: both over 98%; Cobalt ore roughing recovery rate: over 92%; Scheelite tailings recovery rate is higher than traditional flotation process, and tailings recovery efficiency of tin ore, vanadium-titanium ore, etc. is also greatly improved.
