Comparison and Selection of Different Placer Gold Equipment

Gold placer equipment has the following types: fixed chute, agitated chute, belt chute with grid, centrifugal gold separator; jig, shaker. Which one should I use? It depends.

       The fixed chute is made of a simple gold-bonded blanket, which is cheap to manufacture and easy to maintain or even requires no maintenance. It is widely used and is used in almost all small placer gold mines, but the effect is poor. The loss caused by it is a Astronomical figures.

       The cost of the agitated chute is higher than that of the fixed chute, but the selection rate is much better than that of the fixed chute, which can generally reach more than 92%. But maintenance is a little more complicated.

      The selection rate of the grid tape chute is similar to that of the agitation chute, and generally can reach more than 90%. But the maintenance is simpler, and gold can be discharged without interruption. It works well with the centrifugal gold separator.

      The centrifugal gold concentrator has a high recovery rate. In the beneficiation test, the recovery rate of placer gold particles above 0.04-0.074mm can be as high as 95%. Placer gold selection process.

      The selection rate of the jig is slightly better than that of the agitated chute, but the cost and maintenance are many times higher than that of the agitated chute, which is simply unaffordable for small and medium-sized mines. This kind of jig machine has a complex structure, high cost, complicated maintenance, and requires professional staff. It is large in size and heavy in weight (generally tens of tons in weight). It can only be used in large-scale mines, and cannot be used in small and medium-sized mines. As for the simple trapezoidal jump, the recovery effect is almost the same as that of a fixed chute, and the amount of sand produced is small, and it has no practical use value.

       The shaking table is the equipment with the best selection rate among these kinds of equipment, and the price is not expensive, but its sand output is too small, so it can only be used for the treatment of concentrated ore, and it is helpless for the treatment of coarse ore.

       According to the statistical data of various parties and our many years of experience, the selection rate of the agitating chute jig shaker is basically the same, which is more than 10% higher than that of the ordinary fixed chute. Although the investment is relatively large at the beginning, the gold lost by the fixed chute will be lost It will be an astonishing number if accumulated, which is 10 times or even 100 times the cost of the equipment.
