Iron ore mining is primarily a mechanised large-scale activity, but some small-scale manual mining does occur. Small-scale mining uses simple manual tools such as pick-axes, crow bars, shovels and jackhammers to physically extract the ore, which is then hand-sorted, with the highest-grade material retained for sale, and the remainder rejected as waste. Large-scale …
