Natural mineral resources are often found in the Earth’s crust. They are mostly found on land, but also at the ocean floor and undersea volcanoes. The natural distribution of these materials varies depending on the depth of geologic structure below Refresh 24 spa , and the amount of heat and water that mixes with them. In addition to these natural resources being an important source of minerals for industry, they also provide many essential elements essential to human life.
Of all Earth’s natural resources, diamonds are by far one of its most valuable minerals. In fact, diamonds make up about 120% percent of all known economically-viable deposits worldwide. Usually, the only way to determine if a site is diamond rich enough for commercial production is to sample it, return to the surface, and use a machine that can detect their presence.
However, all this searching takes a large amount of time. In fact, it took over 30 years of exploration and mining before diamonds were finally found in South Africa in 1866. If diamonds are discovered in one location, they can be traced to others nearby using surface indicators like kimberlite pipes and rocks that have been transformed by high pressure. The largest diamond deposits in the world are currently located in Russia’s Yakutia region.
1. Barite (Barium Sulfate)
Barite is a mineral consisting of barium sulfate. It is the ore of barium and has many uses. The main use of Barite is in drilling mud, which is a fluid that is used to lubricate drilling machinery and control the flow of rock cuttings from the bore hole during drilling. Barite is also used in the ceramic and paper industries. It can be found in the United States and all over the world. Barite is a by-product of mining for barite and barium (BaCO3).
2. Limonite (Iron Oxide)
Limonite is a naturally occurring iron oxide found in sedimentary rocks. The red color of limonite comes from iron impurities, which are typically present as grains or flakes. It occurs as an iron sulfide mineral, which has two components: FeS and S. The FeS component of limonite forms deep within the Earth’s crust, under water at high temperatures; it reacts with this water to form iron sulfide minerals. The iron sulfide minerals are then precipitated, or formed with a change in chemical composition, as the temperature and pressure decrease.
3. Baryte (Barytes)
Baryte is a lead carbonate commonly found in sedimentary rocks that also contain lime. It is an evaporite mineral that forms at hot springs, seeps, and hot dry lake beds where it is deposited by evaporation of water and dissolution of the surrounding rocks. Depending on the climate and type of rock it is found in, baryte can also form in deserts; this type of formation is known as “frost baryte”. This type of baryte is found in the desert-like badlands of South Dakota.
4. Pyrite (Iron Sulfide)
Pyrite is an iron sulfide mineral with an iridescent tarnish that has many industrial uses, such as being a mineral pigment and a source of iron and sulfur. Pyrite has many names, including fool’s gold, pyrrhotite, and pyrites. It is found in hydrothermal deposits in flood basalts and sedimentary rocks formed from the weathering of volcanic rocks. It is also an ore of copper.
5. Dolomite (Calcium Magnesium Carbonate)
Dolomite is a carbonate mineral that is used in the production of concrete. It is an ore of calcium and magnesium, and can be found in sedimentary rocks. The name dolomite comes from the mineral dolomite, which was named for its discovery along with a rock consisting of dolostone in the French Alps from which it was first mined during the mid-eighteenth century. Dolomites usually form at shallow depths in oceans as well as lakes through the sedimentation process, or when water meets carbon dioxide rich volcanic material.
6. Anhydrite (Sodium Sulfate)
Anhydrite is a mineral found in sedimentary rocks that form from evaporated sea water. It commonly occurs as a brine solution, or when seawater with good drainage finds an impermeable layer of rock and accumulates there.
High concentrations of sulfates on the ocean floor also leads to anhydrite formation. Anhydrite is chemically similar to gypsum and precipitates in similar locations. It is often associated with gypsum deposits, but can be found in many areas with deposits of evaporite mineral formations, including New Mexico and Iran.
7. Calcite (Calcium Carbonate)
Calcite is a carbonate mineral that is commonly found near limestone, in caves and in regions of rock that contain calcium. It can also be found in evaporated seawater deposits and soils that contain calcium or limestone.
It has many industrial uses, including being an additive to concrete and paint. The main use of calcite is as the main raw material in Portland cement, which is the most common type of cement in the United States.
