Froth flotation – Wikipedia

Flotation can be performed in rectangular or cylindrical mechanically agitated cells or tanks, flotation columns, Jameson cells or deinking flotation machines. William Haynes in 1869 patented a process for separating sulfide and gangue minerals using oil and called it bulk-oil flotation.

Hydrogen sulfide – Oilfield Wiki – the Oilfield Encyclopedia

In the purification of metal ores by flotation, mineral powders are often treated with hydrogen sulfide to enhance the separation. Hydrogen sulfide is used to separate deuterium oxide, or heavy water, from normal water via the Girdler Sulfide process.

Cu–Ni sulfide ores. To study possible compositional variations, single pentlandite particles – in the order of 100μm in size from flotation concentrates (PGM deposits) and massive samples (massive ore bodies) – from various sources were employed.

Nickel Sulphide Project Pipeline Empty – Nickel Mining Like its 1864 – Richard Mills –

HPAL (which has up to now enjoyed a highly mixed performance record) involves processing ore in a sulphuric acid leach at temperatures up to 270ºC and pressures up to 600 psi to extract the nickel and cobalt from the iron rich ore – the pressure leaching is done in titanium lined autoclaves.
