Application of mineral–microbe interaction in bioleaching and development of mineral fertilizers. The primary pathways in such applications include (1) acidolysis; (2) redox reaction; and (3) complexation. Bioleaching primarily refers to microbial extraction of valuable metals (e.g. Au, Cu and REE) from low-grade ores, mining wastes and tailings. Mineral fertilizer refers to microbial weathering of minerals and release of nutrient elements (e.g. K, Mg, P and Fe) to support crop growth.
