  2. BCopper from its low grade ores is extracted by hydro metallurgy.
  3. CA furnace lined with Haematite is used to convert cast iron to wrought iron.
  4. DIn vapour phase refining, metal should form a volatile compound.

Correct answer

A. Collectors enhance the wettability of mineral particles during froth flotation.

Step-by-step solution

Collectors enhance the non-wettability of mineral particles during froth flotation.For example; pine oil, xanthates, fatty acids
