Morphology
The verb 'calcine' means to heat a substance to change its chemical composition, and 'limestone' names the calcium-carbonate rock; putting them together straightforwardly yields 'heat limestone to alter its composition (produce lime)'. This is a regular verb + object composition with a directly derivable technical meaning, so a learner who knows both constituents will understand it.
Etymology
Calcine limestone comes from the old practice of heating limestone in very hot ovens until the rock breaks down and gives off a gas. Picture big ovens where the white rock is 'cooked' and the gas called 'carbon dioxide' leaves, leaving lime behind, so the phrase means 'to heat limestone at high temperature to make lime'.
