| titleOfInvention | A kind of method that copper ashes grade is improved in Zinc Hydrometallurgy Process |
| abstract | The invention discloses a kind of method that copper ashes grade is improved in Zinc Hydrometallurgy Process, present invention eliminates the copper ashes washing step in traditional handicraft, it is changed to two sections of pickling of copper ashes, i.e. the copper-cadmium slag high temperature high acidic oils-secondary pulp of the pickling-copper ashes of pulp-copper ashes one time of copper ashes one time --- copper ashes white picking.Present invention process is simple and clear, only need to add sulfuric acid and water in actual production, control temperature, acidity, the technical conditions such as solid-to-liquid ratio, it is simple to operate, production cost is low, pass through this invention, while water-soluble zinc in reclaiming copper ashes and water-soluble cadmium, also the purpose of insoluble zinc and insoluble cadmium in recovery copper ashes has been reached, copper in copper ashes is set further to be enriched with, obtained copper ashes grade is high, copper ashes cupric can bring up to more than 65% from 45%, copper ashes is down to less than 7% containing zinc by 12%, copper ashes is down to less than 3.5% containing cadmium by 8%, whole flow process realizes clean manufacturing truly substantially, it is environmentally safe, with good economic benefit. |
