| titleOfInvention | Method to separate indium and arsenic from each other |
| abstract | A method of separating indium and arsenic from a zinc-containing starting material, wherein the method comprises - a low acid leaching step, in which the starting material is contacted with a first leach liquor in a pH of 2.5 - 5 and at a temperature higher than 40 ° C to obtain a first leaching solution comprising in leached form a first part of arsenic and zinc, - a first solid-liquid separation stage to separate the solid matter from the first leaching solution, - a high acid leaching stage, in which the solid matter is brought into contact with a second leaching liquor at a pH lower than 2.5 to obtain a second leaching solution comprising indium leached and a second part of zinc and arsenic - a recovery stage to separate and recover indium from the second leach solution, wherein in the low acid leach stage the first leach liquor com Sulfuric acid ignites less than 2 g / l, typically less than 1.5 g / l, more typically in the range of 0.1 - 1.5 g / l. |
