The sand extraction potential of embedded .

In the Netherlands, mineral extraction by means of dredging or quarrying meets with considerable societal resistance. Land surface lowering prior to large land reconstruction projects may raise fewer objections. We have calculated the potential yields of sand and gravel from land surface lowering embedded in planned building and construction projects, and in nature, farmland and recreation ...

Offshore iron sand extraction in New Zealand: .

We conducted dilute-acid extractions and standard elutriate tests to investigate the potential of this exploitation to (1) create a new seafloor with elevated trace metal content, (2) mobilise trace metals during iron sand extraction and, (3) enrich the returning process seawater, which feeds iron sand through mills, with trace metals. We found that recruits of freshly uncovered sediment may ...

Oil sands - Wikipedia

Oil sands, tar sands, crude bitumen, or more technically bituminous sands, are a type of unconventional petroleum deposit.Oil sands are either loose sands or partially consolidated sandstone containing a naturally occurring mixture of sand, clay, and water, soaked with a dense and extremely viscous form of petroleum technically referred to as bitumen.

Gravel Extraction - an overview | ScienceDirect .

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 mid-1920s, 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).

Sand and gravel extraction - REFORM wiki

The extraction of sand and gravel from river beds, banks and floodplains is driven by human needs for raw materials for concrete, glass and paint making, and construction works. Direct extraction of alluvial material from river channels causes far greater impacts than floodplain extraction. According to Rinaldi et al. (2005), the effects of bed sediment mining are more severe: where material ...

Environmental consequences of oil production .

We assessed current and potential impacts of oil sands extraction in terms of forest loss, water use, carbon dioxide equivalent emissions, and inhabitants in areas underlain by oil sands deposits in five countries—Canada, Venezuela, the United States, Republic of the Congo, and Madagascar—whose deposits account for the majority of the oil sands discovered worldwide.

The oil sands are strip-mined, and the bitumen is typically separated from sand and clays by an alkaline hot water extraction process. The rapidly expanding oil sands industry has millions of cubic metres of tailings for disposal and large areas of land to reclaim. There are estimates that the consolidation of the mature fine tails (MFT) in the settling ponds will take about 150 years. Some of ...
