Lithology and rock type determination

The size of the individual rock sample examined at the surface is rather small because it is limited by the size of drill cuttings and rock strength Weak rocks, ones without cement, are often reduced to original detrital grain size by the drilling process, making it difficult to determine rock type, but still possible to determine lithology...

Basic Properties of Flue

Three basic properties, such as the grain size, time of setting and the compressive strength of the gypsum are subjected to regulations in the Hungarian Standards if it is meant to be less utilized as a construction binding material The FGD gypsum in question proved to be fine-grained as the grain size of than 012-028% exceeds 02 mm...

fossiliferous limestone: Detailed Description

fossiliferous limestone Fossiliferous limestone is any type of limestone, made mostly of calcium carbonate (CaCO 3) in the form of the mineralscalcite or aragonite, that contains an abundance of fossils or fossil tracThe fossils in these rocks may be of macroscopic or microscopic size The sort of macroscopic fossils often include crinoid stems, brachiopods, gastropods, and other hard ....

Cement clinker

Cement clinker is a solid material produced in the manufacture of Portland cement as an intermediary product Clinker occurs as lumps or nodules, usually 3 millimetres (012 in) to 25 millimetres (098 in) in diameter It is produced by sintering (fusing together without melting to the point of liquefaction) limestone and aluminosilicate materials such as clay during the cement kiln stage...

Flue Gas Desulfurization

This reaction is of great interest in the study of wet flue gas desulfurization process In the case of the normally used absorption additive lime, the oxidation of S(IV) is an essential step in quantitatively producing the final product, gypsum (CaSO 4 - 2H 2 O) Beside detoxication of S(IV) the dewatering properties of gypsum are improved when a high oxidation yield is achieved...
