Sand and Gravel Minerals Education Coalition

DescriptionRelation to MiningUsesSand and gravel deposits found on beaches or in rivers and streams, are mostly quartz (silicon dioxide, SiO2) grains. Weathering of rocks such as granite forms these quartz grains. In the process of weathering, the softer, weaker minerals in granite (such as feldspar) are weathered away. The more resistant quartz eventually is ground down in size, but does not break down chemically. In time, these quartz grains accumulate in rivers, streams, deltas and on beaches.

Environmental Effects of Sand and Gravel Mining on Land

IntroductionMaterials and MethodsResults and DisscussionConclusionsSand and gravel mining refers to the process of removing sand or gravel from a place of its occurrence . These materials occur in a variety of natural settings and are commonly used in the construction industries worldwide. Sand and gravel occur on land, oceans, rivers, streams, flood plains or hills . An increase in demand for sand and gravel for construction purposes has placed immense pressure on sand and gravel resources. Therefore, the extraction of these two important construction aggre...

Sand Extraction: 1. Introduction greenfacts

IntroductionWhere and How Much Sand and Gravel Are mined?What Are The Main Issues with Sand Mining?What Is The Specific Negative Impact from Marine Sand Mining?What Is The Impact on Coastal and Inland Erosion?What Is The Impact of Sand Mining on Inland Biodiversity and Rivers?Are There Economic Impacts Related to Sand Mining?What Can Be Done to Reduce The Problems?Which Regulatory Initiatives Should Be Applied to Manage The Issues?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. 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...
