A 2019 report estimated that the world’s 3,500 large-scale mining operations produce over 100 billion tonnes of solid waste per year. The ratio of useful materials to waste minerals is staggering; waste mass can be several times that of base metals, and can be millions of times that of rare elements such as gold.
