Graduate qualifying work Theme: Selection and calculating of zinc sulfate production technology

Zinc metal is formed from sulfides into sulfates, mineral fertilizers for industrial and agricultural plants, pesticides. Zinc sulphate is used in the metallurgical industry to enrich ores. Zinc sulphate is obtained by heating the zinc sulfide in an oven and selectively dissolving the sulphate compound in the boiling layer. In the metallurgical industry, the method of enrichment based on the property of which the properties of the minerals to be separated from each other differs greatly from each other. However, in order to obtain pure zinc by pyrometallurgical method, the amount of zinc in the raw material should not be less than 16%. Graduation thesis on “Methods and calculation of zinc sulfate”. Zinc and its compounds are introduced in several ways in the production of zinc sulfate.

Main part

The source of zinc is the ore raw material, which is usually in a sulfide state, and zinc is mainly represented by sphalerite (ZnS). Ores are always complex, contain, in addition to zinc, lead, copper, iron, silver, etc. Recently, secondary raw materials have been used in countries with high consumption.

• 
  Approximately 50% of world zinc production is spent on coating iron products to protect them from rust.
  
• 
  More than 30% of all zinc production in the world is used for alloy production. An alloy of zinc with copper and tin is called bronze. Various types of bronzes are widely used in mechanical engineering. Zinc alloys with copper and nickel are called nickel silver and nickel silver. Due to its ability to produce alloys with silver and gold, zinc is used in metallurgy to extract precious metals.
