[ADC12 Price Daily Review] Aluminum futures fluctuate at highs; ADC12 spot consolidates on a strong note

This article examines payment structures in African coltan trading. It assesses how each arrangement distributes buyer and seller risk and highlighting the importance of independent inspection, assay, documentation, traceability, sanctions screening and counterparty due diligence. Coltan is used here as a case study, with the approaches discussed potentially applicable to other mineral trades.

【SMM Cesium & Rubidium Express】Zichang Guoyuan, the only enterprise in China capable of stable mass production of 4N5+ high-purity rubidium and cesium products, has recently achieved a breakthrough in 6N+ ultra-high-purity product technology, further consolidating its leading position in the industry. Relying on the "open competition mechanism for selecting the best to undertake key tasks" project, the company is building an industrial circular economy system for rubidium and cesium raw materials, and has completed the domestically unique production line for comprehensive recovery and reuse of cesium formate waste liquid. As a core raw material for high-end solid-free completion fluids for high-temperature and high-pressure oil and gas wells, cesium formate enables this project to guarantee the independent supply of key strategic raw materials, while opening up intensive export channels to support the 10,000-tonne-level market demand. In the photovoltaic track, the company uses recrystallization purification process to prepare high-purity precursors of rubidium iodide and cesium iodide, which can be used to formulate perovskite coating solutions and prepare rotary sputtering targets, optimize grain boundary defects of perovskite thin films, suppress phase separation, improve thermal stability, and solve the raw material bottleneck for large-scale mass production of perovskite. Industry estimates show that every 1GW of perovskite production capacity consumes about 20 tonnes of rubidium and cesium salts, the 20GW installed capacity in 2027 corresponds to a demand of 400 tonnes of materials, and the 80GW production capacity in 2030 will bring a market space of 1600 tonnes.

【SMM Vanadium Flash News】Starting from September 1,2026, China will resume the consumption tax on all-vanadium flow energy storage batteries, with an initial tax rate of 2%; the tax rate will be raised to 4% starting from September 1,2027. The taxable object of this levy is the terminal product of finished all-vanadium flow energy storage batteries, which is collected at the ex-factory production stage, and does not apply to intermediate raw materials such as vanadium raw materials, vanadium pentoxide and vanadium electrolyte. Sodium batteries and solid-state batteries are exempt from consumption tax before the end of 2028. The taxation will slightly push up the cost of terminal vanadium battery projects, but in the long run, with the growth of long-duration energy storage demand and the maturity of vanadium battery technology, the cost transmission capacity is expected to gradually increase.
