System of circulating fresh air and removing exhaust gases in underground mines. Essential for safety and productivity.
Vertical or inclined opening used to move air between underground levels as part of the ventilation system.
Hydrated phyllosilicate mineral that expands when heated. Used in insulation, agriculture and fireproofing materials.
Resistance of a fluid or slurry to flow. Critical in pumping, thickening and pipeline design.
Rock composed of fragments of volcanic material, transported mechanically or by gravity flows.
Metal-rich deposits formed on or near the seafloor by hydrothermal vents. Major sources of Cu, Zn, Pb, Au, Ag.
Geological processes involving magma generation, eruption and emplacement. Controls many mineral systems.
Formed by processes related to volcanism, including hydrothermal activity and magmatic intrusion.
Electrical potential applied during electrowinning to plate metals such as copper or zinc from solution.
Rock adjacent to an orebody or vein that can be altered or mineralised by hydrothermal fluids.
