Tables 32 and 33 can therefore only be regarded as approximations. Table 32 gives the cost of the straightforward treatment in air-lift machines of a simple ore such as one containing easily floated sulphide copper minerals, and Table 33 that of the two-stage selective flotation of a lead-zinc or similar complex ore.

Solution. Verified by Toppr. Correct option is D. Magnetic treatment. As Iron ore contains magnetic part ( F e 2 O 3) and non-magnetic part ( g a n g u e). Hence, Magnetic Separation is used for concentration of Iron Ore. Hence, Option "D" is the correct answer. Was this answer helpful?
