The most basic of these is building stone. Limestone, travertine, granite, slate, and marble are common building stones and have been quarried for centuries (Figure [Math Processing Error] 6.5.1. 2 ). Some industrial minerals are also used for building materials (e.g. gypsum for plaster and kaolin for bricks).Minerals are inorganic compounds and elements with a regular crystalline structure found in the earth's crust that can be used for a variety of purposes. Resources can often be obtained from minerals or mineral-like matter. This can be broken down into metallic and non-metallic mineral resources.

Unit 1: What Are Mineral Resources and What Makes Them Useful?

Mineral Resources. In this module, we will consider a mineral resource to be a mineral or rock mined from the earth and used in the products we use daily. Brines (salty waters) are also mined for the elements they contain. These are not minerals but do form via rock-forming processes.A mineral resource is a concentration of mineral deposits of economic interest within the earth’s crust. To count as a mineral resource, these minerals must be in a form, grade, and quantity that is of economic interest for extraction. Mineral resources are discovered during the exploration phase of a mineral project.What is a Mineral Resource and Mineral Reserve? — Rangefront
