Sand Extraction: 1. Introduction - GreenFacts

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.

Silicon processing: from quartz to crystalline silicon ...

silicon is tapped from the furnace through a tap-hole at the bottom, and refined by slag treatment or gas purging. During refining, inclusions are removed, and the composition is adjusted to the specified value. Subsequent to refining, the molten alloy is allowed to cool in a mould, and then crushed to a specific size.
