Leaching Kinetics of Antimony from Refractory Gold Ore in

01/12/2020· Ubaldini et al. used alkaline pretreatment method to remove about 80% antimony from refractory ores at 80 °C, and proposed that the removal rate of antimony can be improved by increasing the concentration of sodium sulfide (Ubaldini et al., 2000). Therefore, the leaching of antimony by alkaline sodium sulfide has broad application prospects.

Selective removal of antimony from refractory gold ores by

01/12/2019· The antimony in refractory gold ores was selectively removed by ultrasound with alkaline sodium sulfide. The removal rate of antimony reaches 94.50% under the optimum conditions: the ultrasonic power is 1500 W, the Na 2 S concentration is 2 mol/L, temperature is 55 °C and time is 60 min and the NaOH concentration is 1 mol/L. Ultrasound enhances the removal efficiency of antimony from

Improved gold and silver extraction from a refractory

01/01/2011· The pretreatment of an antimonial refractory gold and silver ore was investigated using alkaline sulphide leaching. The ore assayed 20 g/t Au and 220 g/t Ag and contained predominantly quartz/clay and barite, and to a lesser extent, sulphides such as pyrite, stibnite, sphalerite, zinkenite (Pb 9 Sb 22 S 42) and andorite (Sb 3 PbAgS 6). The latter mineral was identified to be the most important

01/06/2011· The ore used in this study is an antimony-rich refractory gold–silver ore from Akoluk (Ordu-Turkey). The ore samples were reduced in size by crushing and grinding. A laboratory-scale stirred media mill was used for fine grinding (80% passing size, d 80 = 50, 15 and 5 μm) prior to the leaching tests. Particle size analysis of the ore samples was performed by a Malvern Mastersizer 2000 model laser

Improved gold and silver extraction from a refractory

An antimonial refractory gold/silver ore sample obtained from 2.3. Leaching tests Akoluk (Ordu-Turkey) was used in this work. The ore sample was crushed down to −4 mm using jaw and roll crushers and riffled to In these tests, the effects of concentrations of sodium sulfide (0.5– obtain 1 kg representative sub-samples. These were then ground in a 4.1 mol/L Na2S) and sodium hydroxide (1–3.75 mol/L

Alkaline pretreatment of a refractory gold–silver ore containing antimony minerals such as stibnite, andorite (Sb 3 PbAgS 6) and zinkenite (Pb 9 Sb 22 S 42) was tested using sodium hydroxide in order to determine its effectiveness in improving the recovery of gold and silver. Mineralogical investigations show that silver was present as andorite and Au/Ag alloy. Gold particles have been observed as associated
