November 1930. The assay laboratory under construction in the foreground. Buildings behind this are mill office. Structure from right to left: Lead Smelter Stack; Urquhart Shaft Headframe under construction, (it hauled up the first 200 tons of ore on 2nd May 1931). The dark structure is crude ore bins, the ore from underground. The stepped building is the crushers. The first being the primary jaw crushers which then fed into the secondary crushers which broke the ore done to about the size of a golf ball. The conveyor going from right to left carried this finely crushed ore to the fine ore bins which can be seen in this image. These feed the ore to the grinding mills located in the lower right of the bins. These rotating drums have steel balls that grind the ore to a fine grainy slurry. This slurry is then fed into the "concentrator" where it is then processed by "flotation", frothing, to remove the metallic ore from gangue, non ore bearing grains. This froth is thickened and then taken to the lead smelter.
