Using spiral chutes to select gold tailings

Selection of gold tailings using spiral chutes: 1. Introduction: Chute sorting belongs to the inclined surface flow sorting process. Mineral mortar is fed to some inclined grooves or slopes, and under the push of water, the mineral particle group is loose and layered. The upper part of the light mineral quickly flows out of the groove, while the lower layer of minerals with a larger proportion stay inside the groove or discharge from the bottom at a low speed. After obtaining the difference, the selected ore and tailings can be obtained. Spiral chutes are machines for mining and beneficiation, making them ideal for sand mining in coastal areas, riverbanks, sandbanks, and river beds. The product has the characteristics of correct structure, simple installation, small land occupation, easy operation, stable beneficiation, clear screening of ore, large production capacity, high efficiency, high beneficiation enrichment ratio, high recycling rate, and reliable operation. It has the advantages of light weight, moisture prevention, rust prevention, corrosion resistance, and strong applicability to fluctuations in feed volume or density, Granularity, and grade. 2、 The principle of operation is that the slurry is slowly fed to the rotating groove surface through the feeding chute at the end of the spiral groove head, and sorting is carried out. The tail of the spiral groove is equipped with a valve type product acquisition groove, allowing other equipment to be classified into three categories according to grade along the radial direction. By adjusting the orientation of the valve block to change the selection width of each product, the equipment gathering bucket will densely extract the intercepted multi-directional mineral flow. The cross section of the spiral concentrator and the slope change of the curve are extremely suitable for the selection of fine materials. uses spiral chute to select gold tailings. 3. Characteristics and highlights. 1. Heavy duty, high processing yield, and the objective need for contemporary mineral processing to create benefits through economies of scale. 2. Fine granulation: the treatment of fine and small particle size minerals is very important for the treatment of ore materials with a particle size of -0.047MM. The original equipment can basically ensure the recovery of+0.047mm Granularity. 3. With the development of Hydraulics, two-phase flow, equipment vibration, etc., GRP chutes have developed from simple application of gravity and water flow blocking force to composite application of centrifugal force, machine vibration force, magnetic separation force, etc. By using a composite force field, the enrichment of applicable minerals and the separation of fine or fine particles are increased, thereby improving the ore recovery rate. 4. With energy conservation, environmental protection and consumption reduction as the basic starting point, the area and space should be small, and the water and electricity consumption should be small. 5. Simple and flexible operation, stable sorting steps, simple structure, convenient for Computerized maintenance management system. Using spiral chutes to select gold tailings 4. The structure of spiral chutes consists of a feeding device, a cross (tripod), a feeding groove, a rotating groove, a selection groove, a gathering bucket, and a groove pillar. 5、 The spiral chute is suitable for processing 0.6-0.03mm and vein ore or ore sand, but it is unfavorable for sorting when the mud content is high. Nowadays, it has been widely used in the processing of iron, tungsten, tin ore, niobium tantalum ore, beach and river sand mines, as well as sand gold mines.
