Question

Name two important ores of zinc and discuss the principles of extraction​

Answer 1

Answer:

The important minerals in zinc ores are sphalerite (ZnS), zincite (ZnO), franklinite [ZnO(Fe,Mn)2O3], calamine [Zn2(OH)2SiO3], and smithstone (ZnCO3). Zinc ores normally contain 5–15% zinc. Approximately 80% of zinc mines are underground mined, 8% are mined from open pits, and the remainder are a combination of both ores

Principle: Extraction is a method used for the separation of organic compound from a mixture of compound. This technique selectively dissolves one or more compounds into an appropriate solvent. The solution of these dissolved compounds is referred to as the extract.
