Mining is big business, but also one of the world's biggest polluters. A 2019 report estimated that the world's 3,500 largescale 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.

Quartz is a mineral composed of silicon and oxygen, with a chemical composition of SiO 2. It is the most abundant mineral in Earth's crust and is resistant to both chemical and physical weathering. When rocks weather away, the residual material usually contains quartz. This is why the sand at most of the world's beaches is quartz.
