| titleOfInvention | The method of comprehensive utilization of iron ion in arsenic-containing gold ore pressureleaching solution |
| abstract | The present invention relates to a kind of method of comprehensive utilization of iron ion in arsenic-containing gold ore pressureleaching solution, carry out as follows with condition: three-level stirring is acidified: by aurin (in) mine and use the stirring of Oxidation Leaching liquid after first being started with sulfuric acid instead and be slurried and acidification reaction, decomposing carbonate, reaction carries out in concatenated one to No. three stirred tank, and Oxidation Leaching liquid presses formula V=980 ω/CH 2 SO 4 +2.625CFe 3+ Calculated value is added；It is dense: the ore pulp after acidification being entered into concentrator and is settled, then is first added to acidifying solution after alkali starting and is used remaining Oxidation Leaching liquid instead and carry out neutralization removal of impurities；Pressure oxidation: acidification ore pulp underflow is entered into autoclave and carries out pressure oxidation under certain condition；Solid-liquor separation: will aoxidize pulp liquid-solid isolation, must contain H 2 SO 4 30‑50g/L、Fe 3+ The Oxidation Leaching liquid of 18-25g/L, Oxidation Leaching liquid are stored in solution tank reuse.It realizes the acid balance of system, the Fe (OH) for stablizing effect of settling ore pulp, guaranteeing that process is unimpeded, hydrolysis being avoided to generate using the iron replacement sulfur bronsted lowry acids and bases bronsted lowry in Oxidation Leaching liquid 3 Formed colloid, have many advantages, such as it is economical, simple, efficient, be suitable for similar to oxygen pressure factory application. |
