@dtan5457 C right??
OpenStudy (dtan5457):
Not 100% sure but I'm going with C too. Froth flotation is a form of solid-solid separation and it involves melting down the metal so that bubbles will form, so that the differences in reactions to melting, some will float, some will sink, so you separate it... just my thinking, though.
