Hematite - an overview ScienceDirect Topics

Hematite /Itabirite—Research and actual field use has shown hematite to be an excellent alternative to barite. Hematite is an ore composed chiefly of a soft micaceous hematite and small amounts of quartz. The micaceous hematite is very thin tablets or leaves of irregular outline, and the quartz is an aggregate of grains.

Amazing Uses of Hematite You Probably Didn't Know About ...

Hematite is a rich source of iron and has been used for several purposes, ranging from decoration to embellishment. It is a solid mineral substance, which is a rich source of iron. An important ore of iron (present in the form of ferric oxide), it is composed of two molecules of iron and three molecules of oxygen.

hematite Definition, Uses, Facts Britannica

Hematite, also spelled haematite, heavy and relatively hard oxide mineral, ferric oxide (Fe 2 O 3), that constitutes the most important iron ore because of its high iron content (70 percent) and its abundance. Its name is derived from the Greek word for “blood,” in allusion to its red colour. Many of the various forms of hematite have separate names. The steel-gray crystals and coarse ...

Hematite: A primary ore of iron and a pigment mineral

Hematite's Streak: All specimens of hematite will produce a reddish streak. The streak of a mineral is its color in powdered form when scraped across a streak plate (a small piece of unglazed porcelain used to produce a small amount of mineral powder). Some specimens of hematite will produce a brilliant red streak, others will produce a reddish brown streak.

Hematite: Economic Importance

The metallic specular variety of hematite is used as an ornamental stone, for engravings and in some jewelry, typically as beaded necklaces or rings. Mineral collectors also prize some rare hematite varieties as samples. Aside from iron and steel production, the most important historical and economic use of hematite has been as a pigment.

The cement industry is the most important consumer of rubber waste. It uses 236,000 t of scrap tires (26 MJ/kg calorific heat) and 290,000 t of industrial waste (plastic waste, paper, textiles, etc., 22 MJ/kg caloric heat) (VDZ, 1999).Table VI.5.21 shows a comparison of components of traditional fuels and scrap tires.

Hematite: Mineral information, data and localities.

NOTE: The 'hematite' used in jewelry, and often sold as magnetized items, is nothing of the sort and is an artificially created material, see Magnetic Hematite. In an experimental volcanic gas condensation by Africano et al. (2002), it deposited in high f O 2 conditions during cooling from ca. 800°C down to ca. 650°C.

Cement Industry Overview

The cement industry has boosted efficiency by concentrating new capital investment in plants that use the dry process of cement manufacture, and by phasing out operations that rely on the more energy-intensive wet process. Since 1974, the number of wet process kilns has dropped from 234 to 25 -- a decline of 89 percent -- while the number of ...

Types of Cement and their Uses in Construction Industry

Types of Cement Conclusion: Typically, OPC 53 grade cement is suitable for all RCC structures such as footings, columns, beams and slabs. PPC and PSC cement are used for general construction works and strongly recommended for masonry plaster.. The use of PPC reduces the cost of construction and helps improve the quality of the structure.
