Sulfide Ores an overview ScienceDirect Topics

Sulfide Ores. Sulphide ores were mostly created by (i) the intrusion of molten magma from the mantle into the crust of the earth and (ii) the formation of localized metal-rich sulphide ore bodies by sequential solidification and/or hydrothermal leaching and precipitation.

Seven Common Froth Flotation Processes Xinhai

The instant flotation process is especially suitable for the ore with uneven disseminated stone size and the coarse concentrate or medium ore need to be reground. Characteristics: The route into concentrate can be shortened, which realizes early and fast recovery. Above are seven flotation processes.

US4274950A Process for the flotation of sulfide ores

Process using collectors for the flotation of minerals which allow the separation or enrichment of certain minerals, even at pH values around 7. These collectors are organic sulphides of the type R--S--R', in which the two groups R and R' are different and at least one of them preferably carries a substituent including oxygen or sulphur.
