Mining Sand and Gravel. Mineral extraction and processing operations can demand the use of large volumes of water; a commodity that is valuable and in some cases rare. To maximise the process efficiencies and to minimise water consumption the optimisation of water use and reuse is important. On site clarification, sedimentation, dewatering and filtration processes can be aided through the ...

Offshore sand and gravel extraction involves the abstraction of sediments from a bed which is always covered with seawater. This activity started in the early twentieth century (in the mid1920s, in the UK), but did not reach a significant scale until the 1960s and 1970s, when markets for marine sand and gravel expanded and dredging technology improved (Figure 1).

Setting taxes on sand and gravel extraction to create incentive for economically viable alternatives. Reducing the negative impact of extraction : this can be done by modulating the rate of exctaction to the rate of renewal of the resource, and by determining the acceptable limit of extraction.

Sand and gravel extraction on land has a major impact on nature, where animals and plants suffer from mining activities, as well as on human society. This includes nuisances from noise, dust and truck traffic. As a result, spatial planning and environmental policy have restricted the sand and gravel extraction on land. Since the 1960s and 1970s, the demand for marine sand and gravel as an ...

No international conventions regulate the extraction, use and trade of landbased sand (sand quarry, riverine and lake aggregate). Due to operational costs, most marine aggregate extractions are carried out at short distances from landing ports and at water depths of less than about 50 metres. As these activities occur close to shore, they generally are under national jurisdictions. The same ...

The extraction of sand and gravel around and within the river makes the banks of the river weaker and gradually collapses. This does not only leads to filling of the river channel with sediments but gives room for the water in the river to flow out resulting in erosion which washes away the soil. 4. Deforestation.

Because of the instability of sand and gravel, the pit face should never be allowed to get higher than five to eight metres for safe extraction. For deposits of 20 to 30 metres, benches or steps are often used; this approach, called "benching," is not only safer, it also permits easier and less expensive restoration of the land after the pit is closed. Pit floors are best kept flat and ...
