Environmental impacts of mining and processing of sand
Sand-gravel waste is used for land reclamation. All stages of this process are accompanied by the release of dust, which has a negative impact on the nature and human health. The The production of crushed rock aggregate involves the process of mining known as quarrying and it also has some environmental impacts such as noise pollution (PDF) Production and Uses of Crushed Rock Aggregate from

Production and Uses of Crushed Rock Aggregates: An
In areas where natural sand and gravel aggregate deposits are insufficient to handle local demand, larger quarry rocks are processed in an impact crusher to create crushed-rock aggregate. In the quarry, the rocks are extracted and then transported to the rock crusher, which begins the process of crushing the larger quarried At the disturbed floodplain and channel, the combined gravel and sand extraction has exceeded 10 million tons per year. Large disturbances on the Amite River have become much more common due to a steady increase in mining activity in this area. Production reached a peak in the early to mid-1980s.
