Quartz ore is composed of silicon dioxide (SiO2). It may also contain trace amounts of other elements such as aluminum, iron, titanium, and lithium, which can impart different colors and properties to the quartz.

Quartz occurs in a wide range of geological environments, including igneous, metamorphic, and sedimentary rocks. It can form in veins, pegmatites, hydrothermal veins, and as a constituent of sedimentary deposits.

Quartz ore is mined using conventional open-pit or underground mining techniques, depending on the depth and characteristics of the deposit. After mining, the ore is crushed and processed to remove impurities and concentrate the quartz content.
