How sand and gravel quarry works Sand and gravel quarries are much shallower than rock quarries and are usually worked and restored in progressive phases This minimizes the area exposed for quarrying at any time, and limits the period the land is out of use for other productive purposesAggregates account for approximately 85 per cent of the non–energy minerals extracted in the UK and, are critical for the national economy The construction sector relies on the supply of construction aggregates, obtained from 1300 quarries in Britain, dredged from the sea bed by a fleet of 28 marine aggregate dredgers and through recyclingAggregates | Mines & quarries | MineralsUK
