ABSTRACT:
A method of alleviating dust in the early stages of metal ore processing, such as copper ore, through mining the ore through concentration involves spraying and wetting crushed ore rock and ground particles and dust at least several of a series of locations with a dust suppressant containing major amounts of water plus minor amounts of an additive combination of glycerol and a selected non-ionic surfactant, and passing the wetted particles and dust to a metal concentrator where the additive combination does not interfere with metal concentration yield.
