The ore which is concentrated by leaching
- A
- B
- C
- D
Answer & Solution
Correct Answer
(B)
Step-by-step Solution
Detailed explanation
Leaching: It involves the treatment of the ore with a suitable reagent as to make it soluble while impurity remains insoluble and after this, the ore is recovered from the solution by suitable methods. The principal ore of aluminium and bauxite usually contain SiO2, iron oxides…
