Summary of industrial minerals in British Columbia

Traditionally, industrial minerals in British Columbia comprise about 10 per cent of the combined value of mineral, coal, petroleum and natural gas production. Over the years a wide variety of industrial minerals have been produced in British Columbia, often with a different level of marketing success. For some products such as building stone, common brick or expanded shale, once strong demand gradually disappeared; for others such as asbestos and barite, new discoveries or new industrial activities created demand and new markets. For yet other minerals such as fluorite, talc and perlite, wider use has been prevented by the small size, poor quality or remote locations of the deposits. Bentonite (1926 to 1944-as a by-product from coal mines) Building stone (intermittently since the mid-1800s) Chromite (1918 and 1929) Over the past years, the list of industrial minerals produced has been expanded to include several new commodities: glassgrade silica sand, magnesite, pumice and silica for ferrosilicon and silicon carbide manufacture.
