There are also new uses for existing or redundant mines – which again need specialised hoists of custom designs. More standard in concept, but impressively large is the Sishanling iron ore mine in China – 30 million tonnes a year is the planned extraction rate. This is a new project, which Hoist first reported on last year (April 2022).
