How Is Silicon Obtained? eHow

2017-8-30  Silicon as a pure element is almost never found in nature. It is, however, the second most common element in Earth's crust. In nature, it is commonly found as silicon dioxide (quartz), but can also be found bonded with many other elements.

Sand Extraction: 1. Introduction - GreenFacts

2021-4-5  Introduction. Sand and gravel are used extensively in construction. In the preparation of concrete, for each tonne of cement, the building industry needs about six to seven times more tonnes of sand and gravel (USGS, 2013b). Thus, the world’s use of aggregates for concrete can be estimated at 25.9 billion to 29.6 billion tonnes a year for 2012 alone.
