China hot sell gold mining machinery

1. Brief introduction of our gold mining machinery

This model is our bucket wheel type gold mining machinery which is also called gold dredger. The biggest advantage of this type gold mining machinery is that it is less stricted by the terrain even though the river/lake/reservoir bottom is a little hard and the percentage of small gravels/stones is a little high.

The buckets will scoop all the sands and gravels/stones up, then the trommel classifier will separate the sands that contain gold from the gravels/stones.

The extraction efficiency depends on the gold separator. We usually equip gold jig or instigating sluice box and gold carpet on the gold dredger.The recovery rate could reach as high as 85%.

Mining process: Bucket----Trommel classifier----Gold jig----Shaking Table----Gold pan-----Gold furnace---Gold bar
