Relation to Mining (IMAR 7th Edition) In some areas, fluorite rich veins may be weathered to depths of as much as 75 m. Such weathered ore, a mixture of clay and fragments of fluorite and detached wall rock, may be mined open pit with draglines, scrapers, or power shovels to depths of as much as 50 m.

Relation to Mining Most bismuth is produced from mines in China, Mexico and Bolivia. Only one mine in Bolivia is a primary bismuth mine; in other countries bismuth is a by-product of mining other metals. Bismuth is a moderately priced metal, costing more than copper, lead, and zinc, but much less than gold or silver.

Also called silica sand or quartz sand, silica is made of silicon dioxide (SiO 2). Silicon compounds are the most significant component of the Earth's crust. Since sand is plentiful, easy to mine and relatively easy to process, it is the primary ore source of silicon. The metamorphic rock, quartzite, is another source.

About Silica Sand. Silica Sand contains at least 95% SiO2 and less than 0.6% iron oxide. The most common form of SiO2 is quartz, which is mined from hard rock deposits. It is chemically inert and is often white/colorless. However, the color of each sand deposit depends on the variety of minerals and rock detritus that make up the deposit.
