3 Calcium carbide is produced from the reaction of limestone and coke under high pressure and heat. Limestone is converted to lime in a limekiln, while moisture is removed from coke in a coke dryer. The two charged materials are then conveyed to an electric arc furnace, the primary piece of equipment used in producing calcium carbide.
