| titleOfInvention | Method for selective separation of arsenic from copper ore |
| abstract | The present invention provides a method for selectively separating arsenic from copper ore, which can reduce the processing cost with relatively small energy and a simple process. A first step of dry pulverizing copper ore, a second step of adding water or water and an alkali component to the pulverized product pulverized in the first step, and wet pulverizing the second step, After the step, a third step of solid-liquid separation of the water in which arsenic is dissolved and the copper ore component is included. For the pulverization in the first step and / or the second step, it is preferable to use a ball mill and a plurality of balls. The alkali component in the first step is NaOH, and the concentration is preferably 0.5 mol / L or more and 1.5 mol / L or less. [Selection] Figure 9 |
