the role of surfactants in the flotation of molybdenite at climax

10.1016/j.minpro.2016.01.003 | DeepDyve

Flotation of molybdenite is carried out with the use of hydrocarbons (e.g., diesel oil, kerosene, etc.). From this one concludes that molybdenite must differ from other sulfides in that its surface is already hydrophobic ( Chander and Fuerstenau, 1972 ). Molybdenite, as all other inherently hydrophobic minerals, cleaves by rupture of weak ...

If molybdenite is the primary economic mineral, depressants are usually added to inhibit the flotation of other sulfide minerals in the ore. For instance, the flotation of galena has been depressed with sodium sulfide (Mitrofanov, 1957), chromate (Cuthbertson, 1961), and Noke's reagent (Cuthbertson, 1961).

The surfactant or xanthate could absorb on molybdenite edges to improve their hydrophobicity. However, they could also adsorb on other sulfide minerals, reducing the selectivity of molybdenite against other sulfide minerals in differential flotation. Studies to improve the hydrophobicity of molybdenite edges by other reagents are limited.

Quartz porphyry, the primary molybdenum host rock, is commonly veined with molybdenite. Subordinate molybdenum mineralization also occurs in hornfels. The known orebody occurs in two zones of the quartz porphyry stock and hornfels wallrocks. The ore deposit is a molybdenum porphyry, which is classified as a "Climax-type" deposit.

An ore is not just an aggregate of minerals, but must contain metallic minerals in such form and abundance that the metals can be profitably extracted, as indicated in the definition. A mineral such as molybdenite (MoS2) is always molybdenite, but a mineralised rock containing molybdenite may or may not be a molybdenum ore.
