A dry open pit mining method is proposed for ore mining using a combination of scrapers, and an excavator and truck model. The mineralisation is relatively easy digging for an excavator. Normal mining practice will be for the excavator to sit on top of the mineralisation being mined and load trucks in the pit below the excavator.

MINING AND PROCESSING : The major ores of vanadium are patronite (VS 4), carnotite [K 2 (UO 2) 2 (VO 4)3H 2 O], and vanadinite [Pb 5 (VO 4)3Cl].Since much of the vanadium present in the igneous rocks occurs in the relatively insoluble trivalent state, substituting for ferric iron in ferromagnesium silicates, magnetite (an iron ore), ilmenite (a titanium ore), and chromite, the ore deposits

In surface mining, the ground covering the coal seam (the overburden) is first removed to expose the coal seam for extraction. The elements of a surface mining operation are (1) topsoil removal and storage for later use, (2) drilling and blasting the strata overlying the coal seam, (3) loading and transporting this fragmented overburden material (called spoil), (4) drilling and blasting the
