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. The sulphuric acid concentrations will depend upon the leaching techniques used, and the composition of the zinc calcine. In the iron extraction
Solvent Extraction of Zinc from Acidic Solution Obtained from Cold Purification Filter Cake of Angouran Mine Concentrate Using D2EHPA Iranian Journal of Chemical Engineering, Vol.8, No. 3 45 1.2 and (Ni Zn) pH50 − increased from 2.2 to 2.5. Therefore, by increasing D2EHPA concentration up to 40 vol.%, zinc extraction

Aug 01, 2014· The solvent extraction based processes may be judiciously applied to treat the spent pickle liquor for regenerating acid and recycling the metal values. Several reports are availe on the solvent extraction of mineral acids using basic or neutral extractants (Agrawal et al., 2007, Alguacil and Lopez, 1996, Sarangi et al., 2006).
The major types of zinc ore deposits are generally found to be sediment-hosted, volcanic-hosted, intrusion-related, Broken Ore type or Mississippi Valley Type. The Zinc Mining Process. The zinc mining process is conducted primarily underground, with more than 80 percent of all zinc extracted beneath the Earth’s surface.
