TL;DR: Mine sludge contains macronutrients such as P, Ca and S, together with micronutrient like Cu, which points to its potential to be used as a fertilizer, however, the presence of goethite could decrease the mobilization of nutrients to soils, thus additional alternatives, for instance, a mixture with humus or another material containing Humic Acids should be done, in order to minimizing its retention effect.
