Black sands are sandy deposits that contain a high percentage of heavy metals of economic importance because they enter into important strategic industries, and they are named so because they contain a high percentage of dark-black minerals (iron minerals) such as ilmenite and magnetite.
Black sand contains a percentage of economic minerals (ilmenite - zircon - magnetite - rutile - agate) and monazite, which contains radioactive minerals. Many countries extract heavy minerals from the black sands they host due to their economic importance. Also, the beaches are cleared of environmentally harmful radioactive substances
cement, in general, adhesive substances of all kinds, but, in a narrower sense, the binding materials used in building and civil engineering construction. Cements of this kind are finely ground powders that, when mixed with water, set to a hard mass. Setting and hardening result from hydration, which is a chemical combination of the cement compounds with water that yields submicroscopic crystals or a gel-like material with a high surface area. Because of their hydrating properties, constructional cements, which will even set and harden under water, are often called hydraulic cements. The most important of these is portland cement.
Clinker is a nodular material produced in the kilning stage during the production of cement and is used as the binder in many cement products. The lumps or nodules of clinker are usually of diameter 3-25 mm and dark grey in color. It is produced by heating limestone and clay to the point of liquefaction at about 1400 C-1500 C in the rotary kiln. Clinker, when added with gypsum (to control the setting properties of cement and ensure compressive strength) and ground finely, produces cement. Clinker can be stored for long periods of time in a dry condition without degradation of quality, hence it is traded internationally and used by cement manufacturers when raw materials are found to be scarce or unavailable.
