Flotation Reagents Mineral Processing amp Metallurgy

Jun 08, 2016 The flotation reagents can be added in a feed-forward fashion based on the plant raw coal tonnage. Automatic feedback control of the flotation reagent addition rates has been lacking due to the unavailability of sensors for determining the quality of the froth cell tailings. Expensive nuclear-based sensors have been tried with limited success..Fote Mining Machinery Co

Flotation Reagent an overview ScienceDirect Topics

Flotation Reagent. Flotation reagents have two important structural features: a functional group consisting of donor atoms or ligands, and a substituent group, which is hydrophobic consisting of alkyl aryl hydrocarbon chains in the case of collectors and frothers, or hydrophilic in the case of modifiers (except for inorganic modifiers, which comprise mainly inorganic bases and metal ions).

Minerals Special Issue Flotation Reagents

Dec 01, 2019 Reagents are mainly used for treating the surface of ores and/or for improving conditions of operations for increasing flotation separation efficiency. Reagents can impact the pulp chemistry and make flotation a complex system involving the interaction of all additives (including collectors, depressants, activators, pH regulators, and frothers).

Process of froth flotation using a methylene bisxanthate

A process for froth flotation for the recovery of sulfide minerals, or sulfidized oxide minerals, from their ores utilizing a methylene bisxanthate as a collector reagent, either alone or in combination with other known collector reagents in the froth flotation of an aqueous pulp of such ores.

Flotation Behavior of Complex Sulfide Ores in the Presence

Jun 12, 2017 As for zinc, Figure 10 shows that, at 50 g/ton of chitosan, the recovery of zinc in the froth increased by 40% compared to NaCN at its optimum dosage which is undesirable in the differential flotation of sulfide minerals where lead and copper sulfides are floated in the first flotation stages while sphalerite is depressed. Results also revealed ...

Froth Flotation Method JXSC Machine

Dec 20, 2018 Gold flotation. The Froth Flotation Method is means separating minerals according to their different physical and chemical properties. According to classification, the flotability of gold and silver minerals is included in the first category of natural and non-ferrous heavy metal sulfides, characterized by low surface wettability and easy flotation, which can be flotation by xanthate collectors.

The Application of Xanthate in Froth Flotation Process

Apr 11, 2019 Xanthate is the most commonly used collectors for flotation of sulfide minerals. Low-grade xanthate is generally suitable for the collection of easily floatable sulfide ore. And, high-grade xanthate is suitable for the collection of sulfide ore and part of the oxidized ore that are difficult to float.
