Assessment of Gravity Deportment of Gold-Bearing Ores: Gravity Recoverable Gold Test
Original language description
This study investigated the potential of low-grade gold deposits in modern mining, particularly in the context of declining high-grade resources. The primary method for processing these ores was gravity separation with the Knelson concentrator. A GRG test (gravity recoverable gold test) was conducted on two gold-bearing samples: a polymetallic Cu-Zn-Au ore from Zlat & eacute; Hory-Z & aacute;pad (Czech Republic) containing refractory gold and an ore with free gold from Ka & scaron;persk & eacute; Hory (Czech Republic). The study evaluated the effectiveness of the GRG test for gold recovery from these ores. The results showed that the Ka & scaron;persk & eacute; Hory sample predominantly contained relatively large gold grains, with recovery rates dropping significantly upon finer comminution. In the sample from the Zlat & eacute; Hory-Z & aacute;pad deposit, the greatest GRG release occurred in the first and last test stages, suggesting that larger sulfide grains with bound gold passed predominantly in the first stage, while fine gold with residual sulfides passed in the third. Both samples achieved high overall GRG recovery rates, with 64.2% for Ka & scaron;persk & eacute; Hory and more than 66% for Zlat & eacute; Hory-Z & aacute;pad, demonstrating the efficacy of centrifugal concentrators for both ores.
