Hydrometallurgical recovery of manganese, gold and silver

2020-9-1  The elemental analysis of the ore reveals that the contents of gold and silver in the ore are only 1.91 ppm and 23.25 ppm, which are much less than the contents of other elements.The content of manganese in the ore was also considerable. Table 2 reveals that the main minerals in the ore are limonite, maghematite, dolomite, and chlorite, with gold and silver trace minerals.

2020-1-1  Co-recovery of manganese from pyrolusite and gold from carbonaceous gold ore was achieved. The results indicated that the optimum leaching efficiency of 99.31 % for manganese and 97.43 % for gold could be attained under the conditions that the mass ratio of carbonaceous gold ore to pyrolusite was 2:3, the co-roasting temperature was 1073.15 K

US4269622A Recovery of precious metals from difficult

Precious metals such as gold and silver are recovered from difficult-to-treat ores, particularly those containing manganese, by lixiviating using an ammonium thiosulfate leach solution containing copper, sufficient ammonia to maintain a pH of at least 7.5, and at least 0.05% sulfite ion.

Gold leaching from oxide ores in alkaline glycine

2020-12-1  The gold recovery is similar for ores A and D as that for baseline cyanidation as can be seen in Table 4. For ores B and C, which had higher amounts of sulfide sulfur than A and D, requires further optimisation work to improve the recovery to a comparable level as that obtained with cyanidation.

Metal value recovery from metal sulfide containing ores

Metal sulfide gold-containing ores may be leached with sodium cyanide to recover gold, but such recovery is often limited by the metal sulfide content. The metal sulfide in such ores "lock" the metal values (gold) in the ore, for example, by blocking access

This compared to a 87.4% recovery against a conventional cyanidation benchmark with 30% solids, pH 10.5 and ambient temperature using the bottle roll. Other oxidants only achieved a recovery of 11% at best, so permanganate was the focus of the optimisation work. The solution pH had very little effect on gold recovery between 9.5 and 11.5.

2014-4-1  The direct cyanidation tests were first conducted to recover gold and silver from the as-received ores, and the results are shown in Fig. 2. The results revealed that the cyanidation of gold and silver occurred most extensively over a period of 1–30 h. Thereafter, the dissolution of gold and silver appeared to be leveled off with little change.
