Abstract: Described herein are methods for flotation of an ore. The methods include providing an aqueous suspension having an ore in the form of particles, water, and a first frothing agent including a poly(tetrahydrofuran), in a flotation cell to obtain a provided aqueous suspension. The method further includes introducing air into the provided aqueous suspension to obtain a froth. Further described herein are specific aqueous suspensions having ore particles and poly(tetrahydrofuran) and uses of poly(tetrahydrofuran) as a frothing agent for an aqueous suspension having an ore in the form of particles.
