ANTHRACITE. This mineral is extracted directly from the mines and contains a high proportion of carbon, low volatility and low sulfur content, which give it excellent properties for use in reduction processes or as a source of energy. Depending on the origin of the mining basin, there are three types of anthracite:

Smelting iron and steel involves adding carbon to a metal alloy. In this case, specialized materials containing carbon are used, which are called carburizing agents. For this, sinthetic crushed graphite of various grades is used. It improves the properties of the metal, makes it stronger, harder, less viscous and plastic, and reduces the oxidizability of castings during cooling. The ...

Calcined anthracite has been used in conjunction with a resinous pitch to produce a highly effective refractory paste, used in aluminium smelter pot linings. Continuing the theme of refractory paste, it has been found that anthracite-rich resins are far superior in terms of compressive strength at high temperatures than commonly used asphalt-type resins(31).

Calcined anthracite Calcined anthracite is raw anthracite that has been heat-treated. The process, known as calcination, takes place at high temperatures in electric or gas calcination furnaces. Gas-calcined anthracite is produced by annealing in a horizontal gas furnace at a temperature of around 1280 °C.

Anthracite in untreated form is a poor electrical conductor, rendering it suitable for casings with little to no processing aside from grinding (4). For electrode applications, calcination (and thus subsequent graphitisation) is required to improve electrical conductivity.

The effect of a pretreatment using reactive ball milling and calcination on the graphitizability of an anthracite coal is explored. A thermal anneal of Buck Mountain anthracite at 1400 °C in argon increased the L c crystallite dimension (from 12 to 20 Å) and led to an increase in the oxidation temperature of the product. Ball milling of the coal reduced particle size with a …
