Typically, these operations treat over 50,000 t/d of ore with copper head grades below 1%, and sometimes as low as 0.3%. The economic viability of these mines depends on keeping operating costs per tonne of ore below the payable revenue per tonne. For these mines, energy is a significant fraction of operating cost and the main source of GHG ...

Supplementing the use of coal with biomass — a woody or energy crop — has become desirable in the production of electricity for a number of reasons. Coal power plants that have tried to fire dried biomass have learned of the necessity of costly modifications to do so effectively. Yet at the same time, many coal-fired power plants have realized that the benefits of co-firing dried biomass ...
