Such brines can form economically important deposits of sulfate, halide, and borate minerals in thick parallel beds, as the potash deposits at Stassfurt, Ger., and the southwestern United States.

Why Are Minerals Economically Important and Their Impact
Minerals are economically important because it have some incredible usage, frommanufacture tools, construction materials and gemstones to chemical feedstock, beauty products and fertilizers.But the most important thing about minerals is that the come from Natural resources so when there is found concentration of this resource there must There frequently is confusion in the understanding of the terms resources and reserves, and they are sometimes incorrectly used interchangeably.It is important to clearly define these terms and ensure their correct usage. Mineral resources are defined as natural concentrations of minerals or, in the case of aggregates, bodies of rock that are, or may Minerals and the environment Minerals & you MineralsUK

Common Rockforming Minerals. Common Rockforming Minerals. While rocks consist of aggregates of minerals, minerals themselves are made up of one or a number of chemical elements with a definite chemical composition. Minerals cannot be broken down into smaller units with different chemical compositions in the way that rocks Ore minerals are naturally occurring minerals that contain valuable elements or minerals in sufficient quantities to be economically mined and processed for their desired metal or mineral content. These minerals are typically extracted from the Earth's crust and processed to obtain the valuable elements or minerals for various Ore Minerals Formation, Genesis, Occurrence » Geology

Aluminum (Al) Ore Minerals, Occurrence » Geology Science
Aluminum (Al) Ore. Aluminum ore, also known as bauxite, is a naturally occurring mineral rock that contains aluminum in the form of aluminum oxide (Al2O3) mixed with various impurities. Bauxite is the primary source of aluminum, which is one of the most abundant elements in the Earth’s crust, comprising about 8% by weight.The total value of industrial minerals production, including construction minerals, was $58.2 billion. Of this total, $27.7 billion was construction aggregates production (construction sand and gravel and crushed stone), and over $30.5 billion represented production of industrial minerals described in this paper, or nearly 52% of the totalIndustrial Minerals: Society for Mining, Metallurgy

A practical classification is to divide them into non-fuel and fuel minerals. Nonfuel minerals can be further be divided into Metals and metallic resources, natural aggregates, and other industrial minerals, as shown in Table 2. We will study the general mining aspects of nonfuel minerals. Chapter 10 will address fuel minerals.The use of terms associated with formation temperature of ore deposits is common. Examples are epithermal (formed at less than 1500 m and temperatures between 50 and 200 °C), mesothermal (originated at intermediate depths, 1500–4500 m, and temperatures between 200 and 400 °C), and hypothermal (formed at greater than 4500 Mineral Deposits: Types and Geology SpringerLink
