Sand mining is the process of collecting sand from coastal regions, which is used in various manufacturing activities. The most valuable sand is found in dunes and coastal sandstrips. However, sand mining raises environmental concerns, including erosion and disruption of habitats. Sand is a limited resource, and intense industrial mining practices could cause a global shortage. Despite this, sand mining is a major industry, and demand for high-quality sand is likely to increase.
The process of collecting sand from coastal regions is known as sand mining. Sand can be mined from anywhere that is found in large quantities, such as the shores of lakes, rivers, or seas, or it can be dredged from a seabed. Collected sand performs a number of functions and plays an important role in many modern manufacturing activities, such as making roads, concrete and glass. It can also be used to repair damaged ribs.
Sand forms naturally when rocks and other minerals break down. Although the exact composition of sand varies greatly from place to place and depends largely on the type of rock found in any given location, its most common major component is the mineral quartz. The most valuable sand for mining is known as boundless sand, which contains smaller amounts of clay and other impurities than other sands. Such sand is most frequently found in dunes, coastal sandstrip and within sandstone.
Despite the industrial value of sand mining, the practice raises a number of environmental concerns. Most noticeably, sand mining is directly responsible for a large amount of erosion, which can adversely affect a place’s natural ecosystem. The sand mining process can also negatively impact an area’s wildlife, as the fragile habitat of many coastal fish, animal and plant species can be disrupted if the process is not carefully monitored. While laws are in place to prevent such over-mining in many locations, illegal sand mining still often occurs.
Although sand is one of the world’s most abundant resources, making up perhaps 20 percent of the earth’s surface, it is still a limited resource. There is some concern that intense industrial mining practices could eventually cause a global shortage. While sand is constantly being created naturally, the rate at which it is consumed often exceeds the natural rate of replenishment.
Sand mining is a major industry in many places where sand is abundant. Millions of tons of sand are collected every year. Demand for high-quality mined sand is likely to increase as more manufacturing and industrial uses are found for the sand.
