Gypsum: 267.1 million tonnes

Gypsum is a component of a range of construction materials, such as wallboard and cement, and global production of the mineral has increased steadily from 258.1 million tonnes in 2012. China is the world’s largest producer, accounting for 130 million tonnes in 2016, significantly more than Iran, which is ranked second in the world with 16 million tonnes. Smithers Apex reported last year that high demand for sustainable building materials, such as plasterboard made from synthetic gypsum, has driven growth. The analyst estimated that 252 million tonnes of gypsum would be produced in 2016 – a lofty prediction that was surpassed.
