Abstract
Natural biomineral fertilizers for sustainable farming are produced in an environmentally sound manner from mine waste. Finely divided mine waste and process tailings serve as a novel source of rock powder for use as fertilizer. Mine waste and process tailings may be treated with non-toxic chemicals to selectively remove certain unwanted elements such as mercury. Solid and liquid fertilizers are also obtained by digesting mine waste and process tailings in combination with bio-waste plus selected bacteria under anaerobic conditions. Anaerobic digestion also generates methane gas for use as fuel for generating electricity or for process heating.
