Zimbabwe 2 Million TPA Spodumene Ore Processing Plant

Xinhai Solution

• 01

  Petalite dense medium recovery:  Petalite is similar to potassium feldspar, albite and other minerals in nature. The flotation process has poor flotation separation effect, and it is difficult to achieve effective recovery. Xinhai Mining decided to use dense media for recovery before grinding.

• 02

  Tantalum and niobium gravity separation:The by-product tantalum-niobium concentrate is obtained by adopting spiral chute roughing + magnetic separator primary selection + shaker secondary concentrating.

• 03

  Lithium mica flotation: After recovering tantalum and niobium, the tailings enter the lithium ore flotation system, and go through three operations in sequence: desliming - magnetic separation - lithium mica flotation - spodumene flotation to obtain lepidolite (containing rubidium and cesium) and spodumene concentrate.

• 04

  Spodumene flotation separation: Spodumene flotation adopts a closed-circuit process of roughing once, scavenging three times, and concentrating three times.
