Application of Spiral Chutes in Gold Mines

The application of spiral chutes in gold mines. 1. Overview: Chute sorting belongs to the inclined flow sorting process. The mortar is fed to some inclined grooves or slopes, and with the assistance of water flow, the mineral particles become loose and layered. The upper layer of light minerals are quickly discharged outside the groove, while the lower layer of heavy minerals are retained inside the groove or slowly discharged from the lower part. After each is collected, the selected ore and tailings can be obtained. The fiberglass spiral chute is a mining and beneficiation machine, making it ideal for mining and beneficiation of mineral sand on beaches, river beds, sand banks, and streams. The product has the characteristics of correct structure, simple installation, small footprint, simple operation, stable beneficiation, clear mineral separation, high processing yield, high efficiency, high beneficiation enrichment ratio, high recovery rate, and reliable operation. It has the advantages of light weight, moisture prevention, rust prevention, durability and corrosion resistance, and strong adaptability to fluctuations in feed volume, density, Granularity and grade. 2、 The application method is to erect the spiral concentrator, align it with the vertical line, use an iron frame or wood to stabilize it in a suitable position, and use a sand pump to deliver the ore sand to the two feeding ports above the spiral. The sand is mixed with supplementary water to adjust the density of the ore mortar. The ore mortar naturally swirls from high to low, and there is an inertial centrifugal force in the rotating slope flow rate, which varies in density, specific gravity, particle size, and state of the ore sand, The effect of gravity and centrifugal force is achieved through swirling flow, separating the sand from the ore. The selected ore flows into the concentrate hopper and is piped out, while the tailings enter the tailings hopper and are piped to the sand tank. They are then discharged by a sand pump, completing the entire beneficiation process. The application of the spiral chute in gold mines is characterized by three advantages: stability, easy control, and a large concentration range. 2. The production and processing of materials have a high yield, high enrichment ratio, and high recovery rate. 3. Small usage space, low water consumption, simple construction, and no need for power. 4. It is simple to install, easy to operate, with minimal investment and fast returns. Spiral chutes are used in gold mines. They are composed of six parts: a feeding distributor, a feeding chute, a spiral groove, a equipment selection groove, a product gathering hopper, and a groove bracket (including a cross or triangular frame). The rotating groove connected by spiral blades is a key component. The rotating plate is made of fiberglass (fiber reinforced coal gangue), connected together by screws, and the spiral groove has a pre made wear-resistant layer on the selected surface. She has the advantages of being lightweight, sturdy, and durable consumables that are not easily damaged. Above the rotating groove, there is a multi tube feeding homogenizer for ore separation, which is simple and convenient to control. The sieving mineral containers are freely stacked on the cross (or tripod) of the support table. The evenly distributed mortar is slowly fed onto the surface of the rotating groove through the feeding groove installed at the head of the spiral groove, and sorting is carried out. The tail end of the spiral groove is equipped with a valve block type new equipment to obtain the groove. The selected new products are divided into three categories (or four types) according to grade along the radial direction. Change the cutting width of each new equipment by adjusting the orientation of the valve block. The new product gathering bucket is a concentric circular tube that allows the selected multiple ore streams to converge and lead out separately. The slope change of the cross-section and curve of the spiral concentrator is very suitable for the separation of fine particle materials. 5、 The fiberglass chute used in the field can be adapted to the separation of fine iron ore, Ilmenite, Chromite, pyrite, tin ore, tantalum niobium ore, placer gold, coal mine, monazite ore, Rutile ore, zircon ore, rare earth ore and other metal and non-metallic mineral materials with sufficient Density contrast.
