Electrically Calcined Anthracite | African Pegmatite

During calcination anthracite starts to undergo graphitisation at approximately 2,200 C(14). In effect, due to the graphitisation, synthetic graphite is formed as part of the process of producing ECA(15). Electrical calcination is more energy efficient than achieving calcination by gas heating. Graphite itself is a refractory material.

The calcination of limestone is an important reaction in kraft pulp and paper mills since it allows the recovery of lime (CaO) from limestone (CaCO. 3). The lime in turn is necessary to recover chemicals used in the pulp cooking process. The lime calcination process is one of the main fuel consumers and emitters of CO. 2. in a pulp mill.
