The chute is 4 meters long, 0.6 meters wide, the inverted plate is 0.16 meters high, the installation slope is 5-7 °, the bar screen is welded by the 15 mm diameter steel bar, the gap is 15 mm. When the terrain conditions allow, the chute can be applied directly on the bottom plate of the sand ore bed, and before operation, the bottom is covered with sack cloth or wire blanket, and the top side is placed on the grid and pressure bar, fixed tightly to prevent the flow of ore layer. The flow plate is made of linden, willow and poplar wood which is easy to hairy and grows to 2.1 meters, the upper width is 1.1-1.3 meters, the lower width is 0.9-1.0 meters, the angle of inclination is 15-18 °, and the flow plate can be firmly placed on the bracket or the slope which has already been built when the operation is in progress. The gold pan is commonly known as gold dustpan, made of linden or willow. Generally 600-700 millimeters long, 350-380 millimeters wide, 110-120 millimeters high. Its shape side viewed as a triangle, front viewed as a trapezoid, is composed of two triangular and two trapezoidal wooden blocks. It is a commonly used tool for gold separation in alluvial gold mines.
Before beneficiation, dig a rectangular beneficiation pit, and install a chute or flow board in the pit. The surface water will be led up to the wooden chute or flow board, will be dug out of the sand poured on the chute, and with the iron rake in the bar sieve constantly raking, to exclude the larger gravel, 4-8 hours after the pressure can be taken off the bar, the water rinsing grid bar, repeatedly wash the liner. Put the coarse concentrate in the gold panning disk (about 60-70% of the capacity), the disk will be injected into a certain amount of water, the end of the swing, and constantly drainage, sediment is flowing away, leaving only a small amount of gold particles and heavy minerals, at this time the need for careful operation, the gold minerals panning, the rest of the gold particles.
