Froth flotation - Wikipedia

Froth flotation is a process for separating minerals from gangue by taking advantage of differences in their hydrophobicity.Hydrophobicity differences between valuable minerals and waste gangue are increased through the use of surfactants and wetting agents.

Ultrafine particles in ground sulfide ores: A comparison

It was found that for dry milling the yield varies from ~ 0.01 vol.% to 0.2 vol.% for submicrometer particles and from ~ 0.5 vol.% to about 1.5 vol.% for sub-5 μm ones, and increases in the following order: Cu-rich sulfide ore ≤ low sulfide ore < valleriite ore < Kingash ore.

Smelting and Roasting Ores to recover gold, silver and other

However, this “burning” or roasting of the sulfide ores does work well to convert rebellious ores into a more free milling state, allowing the values to be extracted. Exact temperatures used in roasting vary, and excessive temperatures can cause problems, including melting the sulfides before they can oxidize.

Lime use and functionality in sulphide mineral flotation: A

Nov 01, 2019 · Sulphide ores are the major source of valuable metals such as copper, lead, zinc, and nickel, as well as gold, silver, and platinum group metals (PGMs), and flotation is the dominant industrial process to recover these metals via the production of a sulphide concentrate.

Risks to Human Health from Sulfide-Ore Copper Mining
