| titleOfInvention | Method of extracting arsenic from copper-arsenic slurry as arsenic sulfide |
| abstract | This invention relates to a method for recovering a mouse in the form of mouse sulphide from copper-mouse sludgy sludges from electrolytic refining of copper and containing 40-60% copper, 14-25% arsenic and 2-14% lead. The slurry is subjected to alkaline leaching at 60-90 ° C, W: T = 4: 1 for 1.5 hours while simultaneously processing it with elemental sulfur. After leaching, the solution is neutralized with sulfuric acid to pH 2.0-2.5 and arsenic sulphide is separated. Sulfur consumption is determined according to the formula (0.5a + 0.15v + 1.8s /) . 10 -2 kg per 1 kg of sludge, where a, b, and c, respectively, contain copper, lead and mouse in sludge, and sodium hydroxide consumption maintains 2.35-2.45 kg per 1 kg of mouse in sludge. After removal, the mouse cake is recycled for the purpose of extracting copper and lead. The invention allows to simplify the process by eliminating the preliminary heat treatment of the sludge with sulfur, which requires drying the sludge, grinding it, bleaching with sulfur, heating the charge and holding it at 150-200 ° C for 1-1.5 hours. remains at the prototype level of 96-97%. 2 tab. |
