This a complete 40 tph tantalum-niobium ore dressing plant, the raw material is alluvial and rock mixture type, the feeding material size is less than 120mm and there’s a lot of sticky clay in the mine.

1. Washing & centrifugal concentratorseparation

It using the trommel scrubber with a hopper. The hopper also can be made with a grizzly bar to screen the much bigger rocks. Since there’s a lot of sticky in the raw ore, here we suggest using a trommel scrubber to wash away the sticky clay. If you are raw or without too much sticky clay. You can use a trommel screen. Here the machine is with 2 layers of screen, 2 mm, and 25mm. Therefore, rocks more than 25mm will be transferred together. Then the less than 2mm materials will go to a centrifugal concentrator. The tailing from the concentrator will go to the sluice box to gather concentrate again.

2. Jig gravity separation & washing

The 2-25mm materials will go to the jig separator. The jig separator mesh size will be 2mm. Then the 0-2 mm sizes below the mesh from the jig separator and tailing from the sluice box will be sent to a spiral sand washing machine for dewatering. After that, the materials will be sent away by a conveyor belt.

3. Crushing & shaking table gravity separation

The 2-25mm materials above the mesh will be sent to a hammer crusher by belt conveyor to crush to be less than 5mm. The less than 5mm materials will go to the ball mill to grind to be 0-1 mm. After that, you need to feed the 0-1 mm materials into a shaking table to separate and collect the concentrated ore.

4. Magnetic separation

Finally, if there’re too many magnetic ores(like the magnetite, hematite, etc) inside your concentrate ores, you can dry your concentrate at first then use the 3PCS disc dry magnetic separator to remove them and get the final concentrate tantalum-niobium ores.

This capacity of plant can be customized as per request such as 10tph, 40 tph,100tph, etc. Here’s only for processing rock and alluvial mixture ore type, if your situation is different, we support customized the suitable ore dressing plant flowchart for you according to your detailed different ore situation.
