The ore, broken by drilling and blasting, is hoisted through the shaft and conveyed to the processing plant. In some cases, primary crushing takes place underground; in others, a ramp and trucks carry ore to the surface. Extraction and refining. The extraction of copper from ore is normally carried out in three major steps.

Limestone is a naturally occurring and abundant sedimentary rock consisting of high levels of calcium and/or magnesium carbonate and/or dolomite (calcium and magnesium carbonate), along with minerals. ... Processed stone is transported by conveyor belt to the lime kilns. To cook or "calcine" limestone, there must be a significant transfer ...
