Nyrstar to reduce output at Hobart

Due to an increasingly challenging market, Nyrstar will indefinitely lower production at its Hobart zinc smelter in Tasmania by around 25%. The plant’s zinc capacity is 280,000 t/a. “This decision follows a thorough and extensive review and is a direct response to deteriorating market conditions and financial losses being sustained by Nyrstar Australia,” the Trafiguraowned company said. “Nyrstar’s Australian assets continue to face significant financial challenges due to several external factors including worsening conditions in raw material markets, negative treatment charges and increased costs.”

The duration of the production reduction will depend on market and operating conditions, said the plant’s general manager Todd Milne, adding: “We remain optimistic about the future and have the flexibility to lift production levels when operating conditions improve.” The cutback will be implemented in stages from April. “There are no immediate job reductions planned, and the facility will continue to be maintained to retain flexibility,” Nyrstar added.

Last August the company put on hold modernisation of the smelter, which is more than 100 years old, because capex costs had increased by a quarter from the original figure of A$400 million (currently US$251 million). The project included installation of an electrolysis unit and other upgrades to enable greater recovery of minerals and metals at the company’s Port Pirie plant in South Australia. That plant produces commodity grade lead, copper matte, silver dore and sulphuric acid. The Hobart smelter produces special high grade zinc, zinc alloys and sulphuric acid.

Start-up for Adani smelter

Adani Group subsidiary Kutch Copper has commenced operations at its new Mundra copper refinery and smelter, the company announced on 28 March. The company previously indicated an expected start-up by the end of Q1. The new smelter will help boost domestic supplies of copper, demand for which is robust from the construction, transport and power sectors in particular and likely to double by 2030, with the shift towards clean energy and electric vehicles. This first phase of the project will have around 500,000 t/a copper capacity, with a similar capacity planned to be added in the second phase by 2029.

Production cuts at Chinese smelters

It is reported that Tongling Nonferrous is planning production cuts this year given current record low treatment and refining charges (TC/RCs). CRU estimates that the company’s potential cutbacks will total 67,000 tonnes of copper for the year. However, the start-up of the Jinguan II and Chifeng Jinjian II projects could offset the reduction in concentrate demand at operational smelters. Tongling Nonferrous owns five operational smelters/refineries with a total of 1.28 million t/a blister capacity and 1.73 million t/a refined capacity, respectively. It is understood that the Chifeng Jintong 220,000 t/a smelter has cut operating rates by 10% since early March due to concentrate tightness.
