    Travertine processes Ariane phosphate samples

    Arianne Phosphate has provided samples of its phosphate concentrate for processing at Travertine’s facility in Boulder, Colorado, US. Pilot scale testing was successfully performed, demonstrating proof of concept on the process and production of a high-quality purified phosphoric acid (PPA). The Travertine process captures and recycles over 95% of the sulphur used in the process of making PPA, providing a virtually closed loop system. The PPA produced using the process met specifications required for both LFP batteries as well as fertilizers. The companies have begun work to advance the PPA demonstration plant in Quebec’s Saguenay-Lac-Saint-Jean region, working with potential partners as well as end-users of the product.

    Restart for Hongda smelter

    Hongda's 100,000 t/a zinc smelter, in China's Sichuan Province, completed scheduled maintenance and equipment upgrading and officially resumed production on 21st June, the company said. The smelter had been shut down for planned maintenance since January, during which time a modernisation project for the electrolytic zinc smelting system was also carried out. Following the nearly six-month revamp, the resumption of production is expected to improve overall operational efficiency, reduce unit production costs, and increase the utilisation rate, The company said. The stable supply of sulphuric acid generated by the zinc smelter will effectively leverage the synergies of the "sulphur-phosphorus" industrial chain in the company, an help alleviate cost pressures on the company's phosphorus chemical business segment.
