(c) The ore being placed on the heap has an average copper grade of 1.0% and the lixiviant addition rate is 900 m3 /hr. 5% of the liquid is lost through evaporation and other loses and the pregnant solution contains an average of 2.1 kg Cu/m³. The solvent extraction stage recovers 90% of this copper, with the barren solution having additional acid and water added to make up for the lost volume and consumed material before being added back onto the heap. What is the average recovery of the copper from the heap leaching assuming no losses in the SX/EW?

A pipet is used to transfer 5.00 mL of a 1.25 M stock solution in flask “S” to a 25.00-mL volumetric flask “A,” which is then diluted with DI H2O to the calibration mark. The solution is thoroughly mixed. Next, 2.00 mL of the solution in volumetric flask “A” is transferred by pipet to a 50.00-mL volumetric flask “B” and then diluted with DI H2O to the calibration mark. Calculate the molarity of the solution in volumetric flask “B.”

O CHEMICAL REACTIONS Anniston V Solving for a reactant in solution 1/5 One way in which the useful metal copper is produced is by dissolving the mineral azurite, which contains copper(II) carbonate, in concentrated sulfuric acid. The sulfuric acid reacts with the copper(II) carbonate to produce a blue solution of copper(II) sulfate. Scrap iron is then added to this solution, and pure copper metal precipitates out because of the following chemical reaction: Fe(s) + CUSO 4(aq) Cu(s) + FeSO4(aq) Suppose an industrial quality-control chemist analyzes a sample from a copper processing plant in the following way.
