Zinc mining - Wikipedia
The remaining zinc is used in various other industries from agriculture as a fertilizer and human consumption as a supplement. Methods of extraction. Zinc is mined both at the surface and at depth. Surface mining of zinc typically produces ores of zinc oxide, while underground mining yields zinc sulfide ores.
Zinc Hydrometallurgy Solvent Extraction
Part of Zinc Hydrometallurgy and Zinc Solvent Extraction includes the zinc and iron sulphate solution from the hot acid leach will typically contain 80-100 g/l Zn, 20-30 g/l Fe, mostly in the ferric state, and 40-60 g/l free sulphuric acid.
Zinc - Essential stone Industry
Zinc sulfide also reacts with sulfuric acid under these conditions: As shown in the equation, the process also produces sulfur as the element, and this can be used to make the sulfuric acid required. Bioleaching. Very high zinc extraction rates (up to 99%) from low-grade ores (as low as only 5% zinc) can also be achieved using bacterial action.
