Ah, beta, in the lab we see them as clever tricks, like using a magnet to pick pins or soap bubbles to lift dust. Froth flotation uses chemicals to make valuable minerals stick to bubbles, while magnetic separation pulls out the magnetic bits. You choose based on the ore's nature—is it attracted to a magnet, or does it respond to those clever chemicals?
In my verandah, I see the same principle sorting old batteries by type for recycling—some are caught by their metal case, others need a different touch.
