What are the precautions in the process of gold panning?

The working principle of the casserole extractor is that the high-pressure water pump generates high-pressure water and impacts the sand with a high-pressure water gun. Through the wetting, disintegration and flowing action of water, the sand layer deposited for many years forms sand slurry, and then the underwater river sand is sucked up by the suction of the sand suction pump and discharged into the buffer box through the sand discharge pipe. After being decompressed by the buffer box, it flows into the creeping gold panning chute evenly for gold panning. Heavy metals remain in the creeping gold panning chute, and the rest tailings are discharged into the tailings chute, and then discharged to the shore by the tailings pump.
