Compound Annual Growth Rate, a number that describes the steady rate at which the initial value would have to grow every year to achieve the specific end value.


is a thermal treatment process in presence of air applied to ores and other solid materials to bring about a thermal decomposition, phase transition, or removal of a volatile fraction. The process of calcination derives its name from the Latin calcinare (to burn lime) due to its most common application, the decomposition of calcium carbonate (limestone) to calcium oxide (lime) and carbon dioxide, in order to produce cement.

Coke battery:

a coke battery is composed of many coke ovens stacked horizontally into which coking coal is tightly packed. These ovens are heated to temperatures of up to 1,150°C, allowing the coking coal to turn into coke.

Coke conversion costs per tonne:

reflect the operating costs incurred in converting coking coal into coke. It does not include the cost of coking coal charge. It includes consumption of material, energy, services (excluding transportation), personnel and other operating expenses. It does not include depreciation and amortisation.

Coking coal:

high volatility coal used to create coke, which is consumed in the steel-making process.

COP 2010:

the Coking Plant Optimisation Programme is a capital investment programme designed to improve the productivity of its coking operation.

Crude steel:

first solid steel product upon solidification of liquid steel. In other words, it includes Ingots (in conventional mills) and Semis (in modern mills with continuous casting facility). According to International Iron & Steel Institute (IISI), for statistical purpose, crude steel also includes liquid steel which goes into production of steel castings.
