Copper
There is no mineral that is used for all electrical instruments, but in the computer hardware business, silicon is a very important component, as it is used in many computer parts.
A California mineral that is used in making electrical equipment is silicon. Silicon is used as a conductor of electrical impulses and also as a receptor in the makeup of a computer. Silicon chips can hold a multitude of information.
Wires are generally not comprised of minerals, but metals. Examples are copper, aluminum, and gold. There are some insulation systems that use "rock wool" (which is mineral based), for high temperature or high radiation exposure.

The mineral with a hardness of 2.5-3 and that also functions well as an electrical insulator is gypsum. Gypsum is a soft mineral that can be easily scratched with a fingernail and is used in various industries for its insulating properties in electrical applications.
Image result for What is the mineral copper often used to make electrical wires? Because of its superior conductivity, annealed copper became the international standard to which all other electrical conductors are compared. The main grade of copper used for electrical applications is electrolytic-tough pitch (ETP) copper .
