Percentage Of Recovery Of Zinc From Ore

Recovery of zinc from a low-grade zinc oxide ore with

Under optimal conditions, the extraction percentage of zinc was 99.22% and dissolution of silica was as low as 0.56%. XRD examination of the samples demonstrated that all the zinc-bearing minerals were transformed into ZnSO 4 H 2 O while combined silica and iron were changed to quartz and rhomboclase (FeH (SO 4 ) 2 H 2 O) after acid curing, respectively.

How to Calculate Percent Recovery - Science Struck

Calculate the percentage recovery of zinc. Data given: Amount of zinc (original) = 11.23 gm Amount of zinc recovered = 8.67 gm. Solution: Percent recovery = (amount of substance recovered on purification ÷ amount of substance originally taken) × 100 Percent recovery = (8.67 ÷ 11.23) × 100 = 77.20 %. 77.20% of zinc
