Fused state means molten state and calcination means heating of carbonate ore like caco3 in absence of air.

Metallurgy is a process of extraction metal from ore. The metal is obtained fusion state in smelting because during the process of smelting the metal is mixed with slag & a flux. The melting is over high so the metal is obtained fusion state.

Decomposition is the process of breakdown of substances from one phase into another, while calcination is the process of heating a substance to a high temperature, but below its melting point, to bring about thermal decomposition.
