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.
