Tardigrade Admin · Accepted Answer

Calcination is the heating of the ore in a suitable furnace in absence of air much below its melting point to cause decomposition and elimination of volatile products.

P b C O_{3} \to P b O + C O_{2}

The process is generally applied to hydrated oxide or carbonate ores.
