Other crucial properties include streak (the color of the powdered mineral), cleavage (the way a mineral breaks along flat planes), and specific gravity. Hardness, measured on the Mohs scale, varies widely; while talc is so soft it can be scratched with a fingernail, diamond—the hardest natural substance—is also a non-metallic gemstone.
Raw Materials: The Essential Non-Metallic Minerals Powering Industry
The global economy relies heavily on these resources for infrastructure development and the production of everyday items. Defining the Category: What Makes a Mineral Non-Metallic The classification of a non metallic mineral hinges on specific physical and chemical properties that set it apart from metal ores.
The primary characteristic is the absence of metallic elements such as iron, copper, or lead in concentrations that define metallic minerals. Mineral Primary Composition Main Applications Quartz Silicon Dioxide (SiO2) Glass manufacturing, electronics, construction aggregate Gypsum Calcium Sulfate Dihydrate (CaSO4·2H2O) Plaster, drywall, cement retarder Kaolin Aluminum Silicate Hydrate Paper coating, ceramics, paint filler.
