Winter smog-control targets across Yangtze Delta less strict than draft

At 9:58 on September 12, the core smelting furnace of the pyrometallurgy system at Yingkou Jianfa Shenghai Nonferrous Metals & Chemicals Co., Ltd.'s multi-metal recovery project was successfully ignited, officially entering the furnace drying stage and marking a key step toward full-line commissioning and production. Public information shows that the Yingkou Jianfa Shenghai polymetallic complex gold-silver ore comprehensive recovery technology upgrade, relocation, and expansion project uses copper concentrates as its main raw material, with an overall planned capacity of 600,000 mt/year of copper cathode to be built in two phases, with capacity of 300,000 mt/year in each phase. Phase I is designed to produce 300,000 mt/year of copper cathode and 1.18 million mt/year of sulphuric acid, along with supporting systems for smelting, converting, anode refining, electrolysis, slag beneficiation, and precious metal recovery. After this ignition, the project will carry out standardized furnace drying and hot-state integrated trial runs across the entire system to verify equipment, instruments, interlocks, and automatic control systems. The project has not yet formally started raw material feeding and production; after furnace drying and system commissioning are completed, it will further advance the commissioning of Phase I's 300,000 mt/year copper cathode capacity. If the project is successfully brought into production, it is expected to increase copper smelting capacity in North China and further boost domestic demand for copper concentrate raw materials.

[SMM Flash] Amigo Resources reported independent laboratory results from selected Tanzanian material showing combined PGM values of 6.94–7.07 ppm, alongside residual gold values of 3.27–3.47 ppm. The company said it is assessing the integration of proprietary PGM concentration technology into its processing flowsheets to target recovery from gravity tailings and other residual material. Amigo is also evaluating a pyrometallurgical copper-matte treatment route and has mobilised a small-scale furnace for further testwork.​ The programme could potentially establish PGMs as a recoverable by-product from Amigo's Tanzanian polymetallic material if subsequent metallurgical work demonstrates viable recoveries. However, the reported grades relate to selected test material and processing studies and do not constitute a compliant Mineral Resource, reserve or evidence of commercial-scale PGM production. Further metallurgical testing will therefore be important in determining whether the reported PGM content can translate into an economically recoverable product stream.
