sulfidation process during flotation

Behavior and effect of calcium during hydrothermal

During hydrothermal sulfidation and flotation of NS, the phase transition of calcium compounds might play a crucial role in the subsequent flotation for low metal recovery. During hydrothermal sulfidation, calcium minerals in NS were converted and further developed into bulk CaSO 4 crystals with many nano ZnS crystals adhering on its surface.

What is Sulfidation? Definition from Corrosionpedia

Sulfidation is a chemical reaction of a solid substance, such as a metal or an alloy, with sulfur in some form in its working environment. This produces compounds of sulfur that usually form on the solid surface or under the surface of the substance, such as a metal or alloy.

Low Sulphidation Epithermal Gold Deposits

Low Sulphidation Epithermal Gold Deposits. Unlike the muddy acid waters of high sulfidation systems, the low sulfidation fluids are usually crystal clear and have a neutral to slightly alkaline pH. They look good enough to drink but often have high silica, mercury and arsenic contents along with the gold.
