Sinomine Resources Group CO., LTD. acquired Zimbabwe Bikita lithium mine for 1.146 billion. After learning about Xinhai Mineral Processing EPC+M+O service, it signed the contract of Zimbabwe 2 million TPA lithium pyroxene project with Xinhai. Xinhai will provide the mineral processing EPC+M+O service including research and design, all-set equipment manufacturing and purchasing, commission and delivery.
Mineral Beneficiation Process: crushing and screening - lithium feldspar heavy medium recovery - grinding and classification - tantalum and niobium gravity separation recovery - desliming - mica flotation - spodumene flotation recovery - concentrate dehydration - tailings concentrated discharge.
Spodumene Concentrate Flotation: Spodumene flotation adopts a closed-circuit process of one-time roughing, three-time sweeping, and three-time concentrating. Agitating process adopts high-efficiency and powerful agitation tank, which fully guarantees the agitation and circulation effect of chemical mineralization.
Tantalum and Niobium Magnetic-Gravity Separation Recovery: use spiral chute roughing + magnetic separator for primary separation + shaker for secondary separation to obtain by-product tantalum and niobium concentrate.
