| titleOfInvention | Method for quickly removing arsenic in zinc oxide with high arsenic content and producing zinc sulfate by using zinc ash and sodium peroxycarbonate of iron and steel plant |
| abstract | The invention discloses a method for quickly removing arsenic in zinc oxide with high arsenic content and producing zinc sulfate by using zinc ash and sodium peroxycarbonate of an iron and steel plant. The purpose of removing arsenic in liquor is realized by leaching iron in a raw material and then carrying out oxidizing and hydrolyzing reactions to generate Fe(OH)3 by means of a characteristic of Fe(OH)3 which is reacted with arsenic acid at the pH of 3.0-5.4 to generate FeAsO4 precipitates. The method specifically comprises the following steps: calculating the use levels of the two raw materials according to the laboratory reports of arsenic, ferrum and zinc elements in zinc oxide with high arsenic content and zinc ash of the iron and steel plant; proportioning the raw materials; pulpifying; leaching; adjusting the pH value; oxidizing to remove iron and arsenic by sodium peroxycarbonate; neutralizing; carrying out filter pressing; purifying; then, carrying out evaporative crystallization, thereby obtaining a qualified zinc sulfate product. Arsenic enters into smelting waste to be cured in the smelting process, so that harmless treatment is realized. |
