In gold plants, for example, a number of gravity devices, old and new, are being used to recover relatively coarse gold. Over the past few years gravity separators that take advantage of differential specific gravities in a high-gradient centrifugal force field (e.g., Knelson and Falcon separators) have been used successfully for gold.

Small-scale gold mining refers to extraction and processing through manual or partially mechanised techniques, although the scope of extraction, capital invested, and degree of mechanisation is intensifying. With potential for income-generation, mining creates employment and can drive rural transformation.
The most significant limitations are the omission of upstream and downstream processing steps, which will influence the final economic indexes of plant factory scenarios. These omissions are considered as work for future research into the economic modelling of plant factory scenarios.
