Sand mining is the extraction of sand, mainly through an open pit but sometimes mined from beaches and inland dunes or dredged from ocean and river beds. Sand is often used in manufacturing, for example as an abrasive or in concrete. It is also used on icy and snowy roads usually mixed with salt, to lower the melting point temperature, on the road surface. Sand can replace eroded coastline. Some uses require higher purity than others; for example sand used in concrete must be free of seashell fragments.

Environmental impacts of mining can occur at local, regional, and global scales through direct and indirect mining practices. Impacts can result in erosion, sinkholes, loss of biodiversity, or the contamination of soil, groundwater, and surface water by the chemicals emitted from mining processes. These processes also have an impact on the atmosphere from the emissions of carbon which have
River sand mining activities have disrupted the natural equilibrium and have caused adverse affects on the environment. The Nilwala and Ginganga rivers are the main rivers in southern Sri Lanka

The sand keeps the cracks propped open so that oil and gas are released. Frac sand mining creates significant air pollution from the handling, mining, and processing of the sand. The important sources of air emissions come from the tiny dust particles known as particulate matter scattered during mining

Environmental Impacts of Sand Mining Sand mining can use thousands of gallons of water per minute. So how can technology and innovation minimize the impacts on both surface and ground water? The sand mining operation at Tunnel City uses lots of water during the various parts of their processing and mining operations. In fact, they use 15,000
2017-09-08· Skyrocketing demand, combined with unfettered mining to meet it, is creating the perfect recipe for shortages. Plentiful evidence strongly suggests that sand is becoming increasingly scarce in
Environmental impacts of oil sands The environmental impact of the oil sands is an issue that has been extremely divisive. As with the extraction and use of any fossil fuel,negative environmental effects arise as a result of the extraction, upgrading,and processing of bitumen from the oil sands.
Mining, Part 3: In his three-part series, Dr Buck Emberg presents a balanced examination of both the need for mining and the environmental consequences of extracting minerals. He explains that mining has been a human activity since before the Stone Age and will remain so in the future. He contends that mining is here to 
cement, or some other construction use, it becomes clear that the environmental impacts of sand and gravel mining are widespread and cumulative. Below is a partial list of the potential cumulative impacts from the development of a typical sand and gravel mine: • Dust and diesel fumes generated on the haul road to and from the mine.
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.
