Sand mining - Wikipedia
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.It is also used on icy and snowy roads usually mixed with salt, to lower the melting point temperature, on the road surface.

MissionZero - FLSmidth
Combined, cement and minerals production accounts for approximately 10% of all CO 2 emissions. With growing populations, a larger middle class, and a transition to greener energy, the demand for cement and minerals - and thus the environmental impact - will only increase in the next decade.. A more sustainable future requires action from the industries.
Sand Extraction: 1. Introduction - GreenFacts
Introduction. Sand and gravel are used extensively in construction. In the preparation of concrete, for each tonne of cement, the building industry needs about six to seven times more tonnes of sand and gravel (USGS, 2013b). Thus, the world’s use of aggregates for concrete can be estimated at 25.9 billion to 29.6 billion tonnes a year for 2012 alone.
CO2 Emissions Profile of the U.S. Cement Industry
CEMENT PRODUCTION PROCESS Cement’s raw materials, calcium oxide and other minerals (such as silicon, aluminum and iron oxides) are taken from the earth through mining and quarrying. These minerals are crushed into a more manageable aggregate and transported for further processing. The manufacture of clinker and
Environmental impact of mining in the rainforest
Other toxic compounds are used and generated in the mining process as well. Mining exposes previously buried metal sulfides to atmospheric oxygen causing their conversion to strong sulfuric acid and metal oxides, which run off into local waterways. Oxides tend to more soluble in water and contaminate local rivers with heavy metals.
Cement - CEMEX
Cement is a fine powder, obtained from the calcination at 1,450°C of a mix of limestone, clay, and iron ore. The product of the calcination process is clinker—the main ingredient of cement—that is finely ground with gypsum and other chemical additives to produce cement.
