Harvesting Fallen Gold | MW MINING & INSPECTIONS, INC.

Turn of the century mining operations used hundreds of shaker tables or sluice boxes that worked in harmony to process gold. The shaker tables, however, did not do a very thorough job of separating much of the fines and ultra-fines (-100 to -500 mesh), commonly referred to as fine gold, dust or flour.

Developments in iron ore comminution and classification …

 · In addition, mining from deeper areas within pits tends to produce ores that are finer and wetter with a lower lump yield. This typically requires more efficient screening and less crushing. There is also a need to develop economic dewatering and drying processes for the new ore types, due to their high porosity, as mining moves progressively below the water table.
