Guangxi Nonferrous Limu Mining Co., Ltd, a subsidiary of Sichuan Xinjindu Group Co., Ltd., plans to invest in the Phase I of an integrated mining, processing and smelting project covering tantalum, niobium, tungsten and tin.
Phase I will include a 600,000 tpa mining upgrade, a 1.5 Mtpa beneficiation plant, and a comprehensive smelting and resource utilization upgrade project, with total investment estimated at about RMB496 million (USD70.8 million). Phase II will be considered based on the progress of Phase I.
The mining upgrade will target mixed ore containing tin, tungsten, tantalum and niobium, with an annual mining capacity of 600,000 tonnes. Phase I investment is estimated at RMB113 million (USD16.13 million), with a two-year construction period.
The beneficiation plant is designed to produce 4,275 tonnes of tin concentrate and 600 tonnes of tungsten concentrate annually, with an estimated Phase I investment of about RMB156 million (USD22.27 million) and a one-year construction period.
The smelting upgrade project, once fully operational, will produce 500 tonnes of potassium fluotantalate, 50 tonnes of tantalum oxide and 200 tonnes of niobium oxide annually, with Phase I investment estimated at RMB227 million (USD32.4 million) and a one-year construction period.
