A great percentage of the steel was pulled free of the concrete in this operation. The few remaining chunks of concrete that were attached to the steel were sheared free by a man with a pair of hydraulic shears. The steel remaining in the detached concrete chunks was to be removed later at the crushing plant.
The Mining industry is a significant consumer of energy, i.e. 6% to 7% of the total worlds energy is devoted to the industry. Comminution is the major consumer i.e. 40-50% of that total. The grinding process accounts for 90% of the energy required,
