Question

Which of these statements are correct regarding the leaching process?
P: It involves the treatment of ore with a suitable reagent to make it soluble.
Q: During leaching, impurities remains insoluble, and the ore is not recovered from the solution by evaporation.
R: Leaching offers excellent chemical selectivity and flexibility throughout the process.

• A. Q and R
• B. P and Q
• C. P and R
• D. Only P

Answer 1

The correct option is C P and R

Leaching is a process where ore is treated with chemicals to convert the valuable metals within into soluble salts while the impurity remains insoluble.

So, the correct statements are:

• Leaching involves treatment of ore with a suitable reagent to make it soluble.
• Leaching offers excellent chemical selectivity and flexibility throughout the process.
