Energy is the capacity to do work applying a force to move matter. kinetic energy ke is the energy of motion potential energy is energy due to relative position, composition, or condition. when energy is converted from one form into another, energy is neither created nor destroyed law of conservation of energy or first law of thermodynamics.
So, 9 iron ore that is first macerated into 18 crushed iron ore then washed will become 18 purified crushed iron ore, 36 tiny piles of iron dust, and 18 stone dust. which results to 22 iron bars which is 4 more and a total of 13 more than standard smelting but at an extreme energy cost.
