Machine quarrying. Machine quarrying is done by using channeling machines which is driven by steam, compressed air or electricity. In this method, a groove is made using channeling machine around the rock and the horizontal holes are drilled underneath the block. The wedges are driven into holes. Hence, the block gets separated from its bed.

After the coarse ore has been extracted, it is crushed directly at the deposits with the aid of cone crushers or jaw crushers to more manageable sizes of approx. 15 mm. This is also known as lump ore. In addition to lump ore, fine ore (approx. 1 mm) and ground ore (ore powder) (approx. <0.1 mm) can also be obtained by crushing and grinding.
The energy costs required to refine metal values contained in ore to concentrates constitute the majority of the cost to produce metals. On average across the mining industry, 44% of the total electricity consumption is dedicated to crushing and milling activities (Fig. 1).Size reduction operations, nearly 150 × 10 9 kW h, are the largest …
