Sand Mining is an activity referring to the process of the actual removal of sand from the foreshore including rivers, streams and lakes. Sand is mined from beaches and inland dunes and dredged from ocean beds and river beds. A related process is the mining of mineral sands, such as mineral deposits like diamond, gold and silver.

Sand mining is the extraction of sand, mainly through an open pit (or sand 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 .

Sand mining has led to deepening and widening of the Lake Poyang channel, the largest freshwater lake in China and a biodiversity reserve of exceptional importance, and to an increase in water discharge into the Yangtze River. This may have influenced the lowering of the lake’s water levels, which reached a historically low level in 2008.

Sand is the single most mined commodity, eclipsing minerals and metals by a colossal margin. Around 85% of the material we pull up from the earth is sand, gravel or other aggregate materials. Sand is also the most consumed substance after water, being used in virtually every construction or manufacturing process, even used as an ingredient in toothpaste.

Sand mining is a practice that is used to extract sand, mainly through an open pit. However, sand is also mined from beaches, inland dunes and dredged from ocean beds and river beds. It is often used in manufacturing as an abrasive, for example, and it is used to make concrete.

The process was labour intensive with miners digging through the top layer of sand to extract the rich black mineral sand below. By the 1960s these concentrations had been exhausted and the miners moved their operations to the foredunes. Beach mining was hard work with between 25 and 30 men working in teams to shovel sand as fast as they could.

Sand mining is the extraction of construction material from open pits, rivers and stream banks. Sand is essential in the building of physical infrastructure and is an important element in the concrete that is used for construction, which is why in recent decades, the demand for sand has shot up due to rapid urban growth. How does sand mining affect the environment?

Mining sand from the floodplains near rivers is less damaging but it can alter the water’s course, creating dead-end diversions and pits that have proven fatal to salmon in Washington state.

The short answer is yes. The long answer… it’s complicated. Bitcoin mining began as a well paid hobby for early adopters who had the chance to earn 50 BTC every 10 minutes, mining from their bedrooms. Successfully mining just one Bitcoin block, and holding onto it since 2010 would mean you have $450,000 worth of bitcoin in your wallet in 2020.

Mining affects fresh water through heavy use of water in processing ore, and through water pollution from discharged mine effluent and seepage from tailings and waste rock impoundments. Increasingly, human activities such as mining threaten the water sources on which we all depend.
