Appendix:Dictionary of Mining, Mineral, and Related Terms/S/6. a. A layer of rocks, underlying all continents, that ranges from granitic at the top to gabbroic at the base. The thickness is variously placed at 30 to 35 km. The name derives from the principal ingredients, silica .
Silica Sand is quartz that over time, through the work of water and wind, has been broken down into tiny granules. Silica sand deposits are most commonly surfacemined in open pit operations, but dredging and underground mining are also employed. Extracted ore undergoes considerable processing to increase the silica content by reducing impurities.
Comminution (, the breaking of rock to facilitate the separation of ore minerals from waste) combines blasting (a unit process of mining) with crushing and grinding (processing steps). Insitu mining, which is treated under a separate heading in this chapter, is a special case that combines aspects of mining and processing but does not ...
