Process Mineralogy of Jinshan Gold Ore Based on Mineral Liberation Analysis System

Abstract:

Traditional measurement and modern SEM-based mineral liberation analysis (MLA) system were employed to obtain the process mineralogy characteristic of Jinshan gold ore which had high Au (6.20g/t) and low sulfide (0.25%). XBSE, XBSE_STD and SPL_Lt MLA modes are used in this case, which make the results timely, reliable and quantitative. The gold behaves irregular granular native gold or silver-bearing native gold of which the Au content ranging from 93%to 100%. Gold mainly occurred as liberated or in gold-carrying gangue minerals, such as quartz and biotite,rarely in pyrite in the form of fissure gold, inter-crystalline gold or inclusion gold . The particle size of the Gold minerals range from 0.001mm to 0.010mm , which is too fine to recover from beneficiating method. Combined process should be adopted.
