Artisanal and Small-Scale Mining (ASM)
ore bodies, depth, overburden) tend to counter ASM. However, unfavorable conditions for medium- or large-scale mining (irregular ore bodies, steep dipping seams) create a niche for economically viable small-scale mining. ASM makes it possible to mine small deposits which large companies would not be in a position to extract.

Artisanal and Small-Scale Gold Mining Without Mercury
Flotation is usually used by large scale miners but can also be applied in small scale operations. It is a process that works best for processing complex ore types, especially ores that are difficult to process using gravity methods. In flotation, a mixture of slurry (crushed ore and water) and frothing agents are added into a flotation machine.

The Western Miner: A Photo Collection
Leasing was a practice where groups of miners would work a mine for a percentage of the ore they mined rather than a daily wage. This arrangement was advantageous in scenarios where the mine owners did not have the capital to develop the mine. Miners benefited by receiving compensation directly proportional to the success of their work.

Mining projects, the backbone of many small towns worldwide, have a lifespan. The lifespan of an iron ore mine, for instance, is on average between 6 and 24 years (Anglo American, 2013) and thereafter mineral depletion sets in. Economic factors (Burger et al., 2018) and geological factors (Ackermann et al., 2018a) can also render mineral extraction unprofitable.
