Question

Which of the following statements are true for leaching?

• A. It involves treatment of ore with a suitable reagent as to make it soluble.
• B. During leaching, impurities remain insoluble and the ore is recovered from solution by using suitable chemical method.
• C. Leaching offers excellent chemical selectivity and flexibility throughout the process and also minimizes the need for very high temperatures and refractory materials
• D. All of the above

Answer 1

The correct option is D

All of the above

Leaching is defined as a process of treatment of ore with a suitable reagent during which impurities remain insoluble and ore is recovered from solution by a particular chemical method. Do note that sometimes the recovery of the ore could be a direct result of a physical phenomenon (like crystallization).

Further, leaching offers excellent chemical selectivity and flexibility throughout the process and also minimizes the need for very high temperatures and refractory materials
