Gold particles in an ore deposit will vary in size from large nuggets to particles locked in the crystal lattice of sulfide minerals. These sulfide minerals are referred to as gold carrier minerals and contain trace to minor amounts of gold (Taggart, 1927, Chryssoulis and Cabri, 1990).Often it is found that gold ores are refractory due to the small size of the gold …

Mining can be divided into two main energy-use categories: off-grid and grid-connected. Traditionally, most off-grid mining operations depend on fossil fuels such as diesel, heavy oils, and coal for on-site generation and haulage [6].However, grid-connected mining operations are also reliant on fossil fuels, to some degree.
