called asteroids. They are remnants from the early solar system and are mostly made up of rock and metal. They vary in size from small pebbles to large bodies measuring hundreds of kilometers across.
Metal-bearing rocks sought after in mining are typically called ore deposits. These deposits contain high enough concentrations of valuable metals such as copper, gold, silver, or iron to be economically viable for extraction. Mining companies prospect for ore deposits to extract and process the valuable metals.

silicon oxide- SiO2
Not all rocks are metal ore bearing. Metal ore bearing rocks may have as little as one ton in every twenty tons of waste rock. Some metals may be in thin veins and require considerable underground mining. Whether it is worth the effort, depends on the price obtainable from selling the refined metal on the world's metal market.

There is no simple formula to calculate the metal bearing clearance. Manufacturers must specify the clearance for each individual bearing.
