How to upgrade scheelite? And what grade of tungsten can ...

The sulfide ore is usually mixed in the white ore bed with the molybdenite especially common. During the scheelite beneficiation, sulfide ore will be beneficiated by floatation separation, and then the Scheelite will be floated then. The floatation of Scheelite is done in alkaline medium.

impact is generally dependent on the sulfide mineral content of tungsten and tin ore. The principal ore minerals; wolframite series, scheelite, and cassiterite; are moderately to highly resistant to physical and (or) chemical weathering and tend to concentrate in eluvial or alluvial deposits. The mobility of tin in natural environments is low

Sulfide - Wikipedia

Sulfide (British English also sulphide) is an inorganic anion of sulfur with the chemical formula S 2− or a compound containing one or more S 2− ions. Solutions of sulfide salts are corrosive. Sulfide also refers to chemical compounds large families of inorganic and organic compounds, e.g. lead sulfide and dimethyl sulfide.

Uranium ores occur in deposits that are both near-surface and very deep (e.g., 300 to 1,200 metres, or 1,000 to 4,000 feet). The deep ores sometimes occur in seams as thick as 30 metres.

SCHEELITE

The color of the fluorescence of scheelite gives an idea of the unwilled presence of molybdenium in the ore. Concentrate of scheelite not penalized for molybdenium have a distinct blue fluorescence color. Those that fluoresce white are borderline and contain roughly 0,35% to 1% of Mo.

Indium pre-enrichment from a Canadian sulphide ore via ...

The recovery of In metal from sulphide ores by flotation can markedly reduce the costs of subsequent smelting processes and environmental pollution. In this work, the flotation was adopted to pre-enrich the In from a Canadian sulphide ore. The findings of this study can provide a basis for the pre-treatments of In-bearing sulphide ores. 2.
