The increase in the demand for sand and gravel for construction and other purposes such as flood control has placed immense pressure on the environment where sand and gravel resources occur. This study was carried out to determine the environmental effects of sand and gravel mining in Luku, North central Nigeria, using field observations and laboratory analysis of soil samples.
Mining Techniques for Sand Gravel ... Other Sand Mining Methods. Sand dunes can also be mined by dredging or hydraulic methods. This involves a high pressure jet of water to wash the sand into a pond where it is pumped to a storage pile or tank. Where sand is present in the form of loose sandstone, drilling and blasting are necessary.

Sand mining presents opportunities to extract rutile, ilmenite and zircon, which contain the industrially useful elements titanium and zirconium. These minerals typically are found in ordinary sand deposits and are separated by water elutriation. Sand mining is a direct cause of .
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 billion to billion tonnes a year for 2012 alone.
Sand mining activities disturb the functionality of the ecosystems and Langer (2003) indicated that some sand mining activities transform the land use of an area to that of less value or no value at all. This study confirmed this assertion and fig. 4 shows an abandoned
