Zusammenfassung: | The invention discloses a device and process for adsorbing precious metal in acid wastewater in the gold purifying process. The device comprises a base, a depositing mechanism, a wastewater purifyingmechanism, an activated carbon purifying mechanism and a mechanical arm. In use, gold-containing acid wastewater is pumped by a second anti-corrosion fluorine magnetic pump into an activated carbon adsorbing tank, the wastewater adsorbed by activated carbon returns into a wastewater storage tank through a pipeline G3, a closed-loop circulating system is formed, the gold in the wastewater is sufficiently adsorbed by the activated carbon, the activated carbon can be converted from acid to alkali so as to meet the requirements of the electrolysis process and ensure the process safety when the grade of the gold contained in the activated carbon in the activated carbon adsorbing tank reaches 4500 g/t or above, the loss of the precious metal in the acid wastewater in a gold purifying workshop iseffectively avoided, work |
