Quartz is extracted from open pit mines. Miners only use explosives on rare occasions when they need to expose a deep seam of quartz. The reason for this is that although quartz is known for its hardness, it damages easily if it is suddenly exposed to a change in temperature, such as that caused by a blast.
Laboratory analysis of quartz reveals that it is mainly composed of silicon dioxide which can be further processed for silicon extraction. Silicon is the most common and important element in electronic and photovoltaic industry due to following two main characteristics, namely 3 [SYLWAN., 158(6)].

Development of a method for sequential extraction of Si . For the first time, a method for sequential extraction of silicon (Si) from soils has been developed.
the acid base extraction disrupted the quartz mineral structure and as a con sequence releasing more water soluble OSA. Keywords Ortho Silicic Acid, Bangka Belitung Quartz Sand, Acid Base Dissolution, Pre Washed 1. Introduction Silicon is abundant in soil,
In Si and FeSi production, the main Si source is SiO2, in the form of quartz. Reactions with SiO2 generate SiO gas that further reacts with SiC to Si.
EXTRACTION OF Al Be FROM QUARTZ FOR ISOTOPIC ANALYSIS Summary This method is used to separate Al and Be for AMS analysis from pure quartz samples. After adding Be carrier, quartz is dissolved in HF. The solution is sub sampled for determination of total Al content, then dried to remove Si.
Silicon is a chemical element with symbol Si and atomic number 14. It is a hard and brittle crystalline solid with a blue grey metallic lustre; and it is a tetravalent metalloid and semiconductor. It is a member of group 14 in the periodic table carbon is above it; and germanium, tin, and lead are below it. It is relatively unreactive.
Silicon dioxide, also known as silica, silicic acid or silicic acid anydride is an oxide of silicon with the chemical formula Si O 2, most commonly found in nature as quartz and in various living organisms.

FROM QUARTZ TO METALLURGICAL GRADE SILICON Silicon is the second most abundant element in the earths crust, second only to oxygen. It is naturally found as fairly pure silicon dioxide and as silicates. The silicon dioxide is found as huge deposits of quartzite or quartz sand. Moreover, many rocks contain quartz crystals.

This is a research on the extraction and quantification of Silicon from Silica Sand obtained from Zauma River in Zamfara state. The Silica Sand sample was removed from the water in Zauma River which was allowed to dry and heated in a heating mantle. Silicon and Silica was extracted from the sample. Quantitative analysis of the sample was then done
Quartz is composed of silicon and oxygen and is common throughout the world, although most of it is not crystallized. Crystallization occurs when the silicon dioxide or silica is heated. The source of the heat can be extremely hot water from underground sources, which fills open fissures to create filled quartz
