Raw materials for the production of zinc oxide

  

  1. Zinc mine;
  2. Zinc calcine: It is produced from zinc ore and is the product of zinc concentrate after roasting. It mainly contains zinc oxide, zinc sulfate, zinc sulfide, etc. It is mainly used for zinc smelting and is the most important raw material for zinc smelting.
  3. Zinc ingot: 0#~5# zinc, 0# zinc is the best, arranged in order, 3# (including 3#) is called crude zinc afterwards, and the essence of crude zinc is zinc slag. 0# and 1# are extracted from zinc ore, and 2# is less involved and is basically the defective product of zinc ore.
  4. Zinc dross: during the production process of galvanizing enterprises, there will be zinc ingots of slightly poor quality that sink to the bottom of the pot, which is zinc slag, which is divided into scum and bottom dross. Zinc slag is mainly produced by galvanized sheet enterprises. Among them, the zinc dross produced by the plated plate and the plated pushpin must be good for the galvanized plate (the quality of the plated large pieces is better than the plated small pieces of zinc dross), and the scum and the bottom dross are good; Monthly fishing or half-month fishing (referring to the frequency of galvanized sheet companies salvaging the bottom zinc slag), half-month fishing is better. Therefore, there are many factors influencing the quality of zinc slag, and the specific conditions are treated specifically.
  5. Zinc ash: zinc slag after oxidation.
  6. Secondary zinc oxide: It is the material attached to the side of the pot during the zinc oxide firing process. Its purpose is to further process electrolytic zinc or zinc oxide, and some are also used for replacement.
  7. Zinc powder: Literally speaking, the zinc ingot is made into powder. The actual products are divided into metal zinc powder and electric furnace zinc powder. Metal zinc powder is physically crushed by zinc ingot, and electric furnace zinc powder is produced after electrolysis of zinc ingot. Classified by particle size.
