A large fluorite-lined vug is present on the north-east face, but is now submerged. On the opposite face at this point calcite veining is evident in the toadstone, and the primary calcite vein was mined for nickel minerals. The adits in the north-west of the quarry represent the remains of the former underground workings on the vein.

The initial tests were focused on the extraction of nickel and cobalt from both samples. Preliminary results indicate that both the massive sulphides and the rougher sulphide tails are amenable to bioleaching with very high extraction rates for nickel (96.1-98.5%) and cobalt (96.1-97.7%) (Table 1).

Nickel extraction by bioleaching from laterite ores and MTs has reached 8–26%, with aerobic conditions and microwave pretreatment enhancing nickel yields. Up to 91.5% nickel recovery from low-grade sulfide tailings and 53–57% extraction in just 7 days have been attained via novel bioleaching techniques [129]. Similarly, the fungus ...

The primary aim of every twenty-first century mining operation is to extract as much ore as possible in a safe and economical manner. Failure in mine excavation occurs when the shear stress acting on the rock is greater than the shear strength of the rock mass. The stability of rock slopes in open-pit mine and quarry operations is extremely important from both economic and …

A higher FM means a generally coarser aggregate. Shown in Table 1, both quarry dust and nickel slag had an FM greater than sand. Interpreting these data in conjunction with the graph shown in Figure 2 indicates that the combination of quarry dust and nickel slag as fine aggregate provides a more well-graded particle distribution than natural sand.
