Mining methods depend primarily on the degree of cementation of the rock. In some deposits, blasting is required to loosen the material prior to processing. The material may undergo primary crushing at the mine site before being transported to the processing plant. Figure 11.19.1-2 is a flow diagram for industrial sand and gravel processing.
Industrial sand is sometimes called "frac" sand or silica sand. The extracted sand is often processed locally. Processing of the sand typically involves washing and separating the sand into grain sizes suitable for hydraulic fracturing. The sand is then shipped out of state for use at gas and oil fields for hydraulic fracturing.

To model high-quality silica sand extraction rather than sand production, a drying step was added to the process. Based on those assumptions, the carbon footprint is 22.7 kg CO 2eq and CED 339 MJ per metric ton of silica sand. The drying process is only a valid assumption for quartz containing more than 98% silica.
Concerns with mining raw materials According to the US Department of Energy (DOE), about 12% of all silicon metal produced worldwide (also known as "metallurgical-grade silicon" or MGS) is turned …

Copper smelting involves three steps: Roasting: First, ore concentrates are roasted or heated to remove sulfur and moisture. Smelting: Then, copper concentrates are mixed with silica (sand) and limestone and heated in a furnace to form two naturally-separating layers. One layer is a waste containing iron and silica compounds and is …
