• How Is Sandstone Mined? Career Trend

    Aug 26, 2019· Geologists can identify where sandstone came from by examining the mineral composition. Sandstone ranges in color from white to yellow, orange, red, green and purple. The colors in the sandstone come from the minerals it mixed with while it was forming. Sandstone is mined through the quarrying process.

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. This production represents enough concrete to build a wall 27 metres high by 27 metres wide around the equator. Aggregates also contribute to 90% of asphalt p.
