Urquhart Shaft Headframe and Assay Building, Mount Isa Mines, c.1932

DESCRIPTION

DescriptionGeneral View looking North to the Mill. The concentrator, where the finely crushed ore is removed from the country rock by a flotation process involving chemicals, water and air. The concentrate is captured by the air bubbles creating a froth which rolls off the top to be then further treated. The building between headframe and the flotation is crusher and crude ore storage. This crushes the ore to a smaller size and transfer it to the concentrator on a conveyor belt to the Fine Ore bins, the sloping structure. The headframe is for the Urquahart shaft, known also as No 1 Ore Shaft. This raises the large size ore from 4 level in skips and dumped into the Crude Ore bins which then feed the Jaw Crushers and this requires smaller crushing done by the cone crushers.
The white building in the bottom right is the Assay Building. Next to the headframe is a large process water tank, this is filled by recycled water from the tailings dam.DateCirca 1932RightsCC: BY-NC-SASubjectMiningMining Sites
