Americas Tailings is working in collaboration with California-based Advanced Materials Processing Inc. to advance an innovative technology to extract nutrient value from tailings and repurpose it into an organic fertilizer. The technology combines tailings rock feedstock with biomass material to produce a bio-mineral soil fertilizer where elements typically considered deleterious or contaminants (N, P, K, Ca,Mg, Mn, Cu, Zn) are key ingredients to produce nutrient-rich fertilizers.
Laboratory and pilot work on material from porphyry copper and lead-zinc tailings sites have been successful to produce products with agronomic value based on nutritional elemental content. Americas Tailings is continuing to advance its understanding of the fertilizer composition, the efficacy of the fertilizer on plant growth, and the process flowsheet and equipment requirements. Planned development work includes design of a mobile pilot plant program with capabilities to produce small-scale fertilizer production as a prototype for an industrial scale operation.
Development work is being advanced with proprietary and licensed technology, designs, and processes. The modular nature of the design will enable build-out of the technology to an optimal commercial scale to match feedstocks and fertilizer markets for specific projects.
