Silica (SiO2) is the name given to a group of minerals composed solely of silicon and oxygen. Found most commonly in the crystalline state, it also occurs in an amorphous form resulting from weathering or plankton fossilization.
Calcium carbonate is a very versatile mineral found in many everyday items, from binders and sealants to animal and landscape feed.

AN INTRODUCTORY ARTICLE ON MINERAL ORES.
Ore: a type of rock that contains minerals in its composition and structure, provided that these minerals contain metals, as it is possible to obtain such ores by carrying out the mining process in the ground or on the surface. The mineral may be called ore if it contains sufficient and useful quantities of materials that can be sold, invested and profitable, as the ore is processed immediately after its extraction until the required mineral or element is obtained. Most of the materials or metals that humans use come from a variety of ores, and most of the time these ores are from the iron metal that is used in the manufacture of steel.
Mineral ores: it is a group of metallic elements that are linked with other elements chemically bonding, where this bonding leads to the formation and formation of mineral agglomerates that mix these clusters with the rock components or with non-metallic minerals, where these materials or components are called impurities, and these clusters are considered to Economic importance and mineral wealth obtained after the completion of the mineral extraction process. In addition, minerals that contain sufficient quantities of the metal to be easily and conveniently extracted are called ore. For example, galena, which is the same as natural lead sulfide, contains very large quantities of lead, so it is considered a major ore mineral for lead. It is worth noting that the metal must be sufficiently concentrated in the mineral until the ore is formed, and this mineral must be sufficiently concentrated in the ground, as the presence of ores or metallic ores may be concentrated in certain areas. This limestone may be considered one of the most important mineral ores. Due to its multiple uses, such as entering the manufacture of cement and tiles in addition to its use in the manufacture of building and construction materials and the manufacture of paints and paper
Methods of formation of metallic ores
The mechanical method: this method includes all the weathering and erosion processes that break up the rocks and form multiple deposits that are carried and deposited by multiple transport factors, which leads to the formation of mechanical sedimentary rocks within their different environments, in addition to the formation of mineral and gravel deposits on the banks of rivers
The chemical method: where mineral ores are formed by the interaction of living organisms with surface water and this is known as organic chemical precipitation, or through direct precipitation from seas and oceans, resulting from the process of evaporation due to high temperatures. Mineral ores can be formed by the occurrence of magma crystallization either on the surface or at varying depths from the surface of the earth.
