Mine waste source for bio-mineral fertilizer to remineralize agricultural soil

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...

Zusammenfassung:	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.
