Copper king Chile faces acid supply crunch as China exports dry up

From Mining.com

China’s exports of sulphuric acid to Chile dwindled to zero in March, Chinese customs data show, leaving the world’s top copper producing nation facing a squeeze on supplies of the chemical used to make around half of its refined metal.

The war in the Middle East has caused a sulphur supply crunch, and China is reportedly planning to ban sulphuric acid exports from May to ensure its domestic market – notably the fertilizer industry – does not face a shortage.
