    Smelters process Chilean concentrate for free


    Smelters process Chilean concentrate for free

    The mid-year negotiations between Antofagasta (AMSA) and Chinese smelters have concluded with a historic settlement of $0/0¢. While unprecedented, the outcome is not surprising, as it lands slightly above the midpoint of the believed negotiating range, from -$15/-1.5¢ proposed by Antofagasta +$10/1.0¢ from the Chinese smelters. Moreover, this result aligns with market participants’ rumours circulating prior to the agreement. Separately, rumours suggest Q3 contract negotiations between one top miner and Chinese smelters concluded at levels ranging from -$25/-2.5¢ to (+)$5/0.5¢.

    As is to be expected in long-term negotiations, the agreed price remained firmly above the first half average of spot terms, although stands out this time is the absolute difference of $24/2.4¢ units, which far exceeds the $17/1.7¢ unit deviation observed in 2021. Although this does not imply a perfect correlation between the first-half average spot terms and the mid-year benchmark, it does suggest that smelters could have faced a more challenging scenario, potentially even forcing them to accept negative terms under tighter market conditions.

    Nickel Industries starts up ENC acid plant

    Nickel Industries announced started up the sulphuric acid plant at its new Excelsior Nickel Cobalt (ENC) HPAL project in the final week of June. The ENC Project is a massive, multi-billion dollar high-pressure acid leach (HPAL) facility located in the Indonesia Morowali Industrial Park (IMIP) in Central Sulawesi, Indonesia. It is operated by Australia’s Nickel Industries to supply battery-grade materials for the electric vehicle (EV) market. At capacity, it is expected to yield roughly 72,000 t/a of contained nickel equivalent as mixed hydroxide precipitate (MHP), nickel sulphate, and nickel cathode.

    Russia bans rail transport of Kazakh sulphur

    Russia has ordered a “temporary cessation” of rail transport of all sulphur originating from Kazakhstan that is destined for Russian seaports and railway checkpoints, representing a significant policy shift, according to an official order from the Federal Agency for Railway Transport (Roszheldor). The directive, which took effect from May 26th, orders a halt to the loading and movement of Kazakh sulphur “until further notice.” While the measure is officially described as temporary, the order provides no specific timeline for when the transit might resume. The action cites instructions from Russia’s First Deputy Prime Minister, D.V. Manturov, as its basis.

    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.
