Process to recover base metals - SEELEY LARRY E.

The leach liquor was neutralised with HCl, precipitating a tellurous acid/oxide mixture. After much investigation, the Na2S/Na2SO3 process was chosen, as it had many advantages. In this method, the cyanidation residue (either a cyanided calcine or a cyanided chemical oxidation charge) is … where Q is the mass of the sample before leaching, M is the mass of the leach residue, and and are the copper, lead, or zinc grade of the calcine before leaching and the leach residue, respectively. 3.

The compounds present in the calcine were the same at 25 °C, 55 °C, and 75 °C, but differences formed in the leach residue generated at different temperatures. When the temperature increased from 25 °C to 75 °C, the PbSO 4 content of the leach residue increased, reaching a  · A process for recovering aluminum from alunite ore directed to providing a residue for the Bayer leach step substantially free of impurities so that a high A/C ratio Bayer leach liquor is produced, which comprises roasting the ore in particulate form to drive off water and sulfur as SO 2 and to convert aluminum sulfate to alumina, leaching the residue containing aluminum values with water and ...

The autoclave process also includes a two-stage energy recovery system and a vent-gas scrubbing system. The main process connection of the calcine leaching plant process is presented in Figure 3. Figure 3. Showcase of our technology. After the autoclave the leach residue is filtered and sent to the gold and silver recovery steps. [4]. Roasting, pressure oxidation, biooxidation, ultrafine grinding and modified cyanidation are the pretreatment methods currently practiced for refractory gold ores and concentrates[5−6]. Ultrafine grinding is a physical method for the liberation of locked gold when efficient size reduction is achieved[7]. However, gold present as
