Task 4. Mine Tailings Reuse

2020-10-13 · Reuse of tailing s, rather than starting with new solid rock, also reduces energy input for products requiring finely ground rock, since large amounts of energy have already been used to grind the rock to a fine sand-like consistency. Finally, mine tailing reuse is another step toward achieving zero-waste operations. Problem StatementThe mechanics of a silt-sized gold tailingtages, which indicates that the major minerals within the tailing are quartz (22.1%), albite (25.0%), chlorite (47.1%), and calcite (5.9%). The present finer gold tailing contains twice the quantity of chlorite (which belongs to clay-sized minerals) as the coarser one tested by Bedin et al. (2012), but it did not give any plasticity to the soil.
