In ores
The most useful minerals often occur in rocks and ore deposits. These minerals are typically found in areas with geological processes that concentrated them, such as near tectonic plate boundaries, volcanic regions, or areas with hydrothermal activity. Mining operations are established to extract these minerals for various industrial and commercial purposes.
Some of the most useful physical properties of minerals include hardness (measured on the Mohs scale), cleavage and fracture (how a mineral breaks), color, streak (color of mineral powder), luster (appearance of a mineral's surface), and crystal habit (the shape in which a mineral naturally occurs). These properties help identify and classify minerals.
Chlorine gas does not occur naturally as it is too reactive. Chloride salts occur naturally. The most common is sodium chloride, NaCl. Chlorine, Cl2, is obtained by electrolysing molten NaCl.
Halogens occur naturally in various minerals and salts, as well as in seawater. These elements are most commonly found in combination with metals like sodium, potassium, and magnesium. Halogens are highly reactive and will readily form compounds with other elements in the environment.
Yes it does. The quartz countertops that you see in houses are engineered, but quartz also occurs in nature, and is actually pretty common.

Crystals can be made from just about anything. In fact, most minerals naturally occur in a crystalline form. Salt, sugar, and ice are all examples of crystals.
