Efficiency as a Road to Sustainability in Small Scale

These are all signals of a future development of small-scale mining in precious metals, especially gold, in the next decades.The economical sustainability of a SSM installation depends highly on a capable optimization of the assets with which it is equipped. This conclusion, as proved in paragraph 2.2, is very important: it clears that the sustainability for SSM is strictly endogenous, and it depends on its own capability of operate in an efficient manner. When, through operative efficiency ...
