Fluorite has three main types of industrial uses depending on its grade. Metallurgical grade fluorite is used in iron and steel production. Fluorite is used as a flux to lower melting points of molten metals and remove impurities such as phosphorus and sulfur. Every ton of metal produced requires 20 to 60 pounds of fluorite.
It crystallizes in isometric cubic habit, although octedral and more complex isometric forms are not uncommon. Fluorite is a colorful mineral, both in visible and ultraviolet light, and the stone has ornamental and lapidary uses. Industrially, fluorite is used as a flux for smelting, and in the production of certain glasses and enamels.
Quartzrich rocks like quartzite and quartz sandstone are often used as building stones and some colored quartz varieties are used as ornamental and semiprecious stones. By volume though, the bulk of all commercially mined quartz is used in the construction industry as aggregate for concrete and as sand in mortar and cement.

In these rocks, calcite is often the only mineral present, but in some sedimentary environments, calcite may be associated with dolomite, gypsum, anhydrite, chert, or halite. In hydrothermal veins, quartz and other common vein minerals such as pyrite, dolomite, fluorite, galena, and .
The uses and properties of the mineral Dolomite. What is Dolomite? Dolomite is a common rockforming is a calcium magnesium carbonate with a chemical composition of CaMg(CO 3) is the primary component of the sedimentary rock known as dolostone and the metamorphic rock known as dolomitic that contains some dolomite is known as dolomitic limestone.
The following are some of the more common uses of calcite. Uses Of Calcite. The primary use for calcite is in the construction industry. The products containing calcite, limestone and marble, are commonly used on building projects. These are commonly used to create cement or concrete. Calcite is also used in commercial acid neutralization.
Siderite is a mineral composed of iron(II) carbonate (FeCO 3).It takes its name from the Greek word σίδηρος sideros, "iron". It is a valuable iron mineral, since it is 48% iron and contains no sulfur or phosphorus. Zinc, magnesium and manganese commonly substitute for the iron resulting in the sideritesmithsonite, sideritemagnesite and sideriterhodochrosite solid solution series.
