POLYOX™ polymers provide many need functionalities in various mining processes. They act as flocculation aids for heavy metal ores, clay, silica, and oxidized coal fines in solid separation units and tail recovery systems. They also provide an increased dewatering efficiency for improved process water recovery and recycling. POLYOX™ is also used to treat the

17/02/2006· Saltpeter Mining. When mixed in proper proportions with sulfur and charcoal, saltpeter—or potassium nitrate—forms gunpowder. The ability of early colonists to procure their own supplies of this essential substance enabled them to successfully fight the Revolutionary War (1775-83) despite blockades by England.
