When mining metals and industrial minerals it is inherent in the process that a certain proportion of the productive material will be left behind in the tailings. While these mineral residues, some of which are recyclable, were not the focus of attention at the time the minerals were being mined, they have more recently taken on growing significance, as in the case of rare-earth metals. With the international demand for raw materials growing, and the metal content of primary ores tending generally to decline, we are now seeing a continuous escalation in the quantity of material being disposed off in spoil tips. Enormous quantities of mining refuse from raw-materials extraction are now to be found in the spoil tips and tailing ponds of current and former mining countries and work has been … Read more<\/a>\n
