Oct 26, 2016 The high demand for gold and the fluctuating gold prices have necessitated the need for processing of lower grades ores, waste rock dump materials and scrap residues. Bacteria are now increasingly being used to facilitate the extraction of metals from low grades ores and concentrates (bio mining) that cannot be economically processed by.
Aug 18, 2020 G t is the universal measure of the concentration of a precious metal found in an ore deposit and measured on a scale of gold in grams per tonne. Certain ore samples show grades over 300g t. This is significant because on average, native gold ore grades vary between 8 and 10g t at Barberton, and much lower on average anywhere else in the world.Read More
