Purpose Of Different Reagents Used In The Flotation Cell

Flotation Reagents - Mineral Processing & Metallurgy

Among the flotation reagents, commonly used activators for flotation are sulfuric acid, sulfurous acid, sodium sulfide, copper sulfate and so on. Inhibitors: It is a kind of reagents mainly used to increase the hydrophilicity of minerals and to form a hydrophilic film on the surface of the ore particles in flotation process.

Flotation Reagent - an overview | ScienceDirect Topics

Activators, depressants, and pH regulators are often referred to as modifiers or regulators of the flotation process. The main purpose of these reagents is to modify the action of the collector on mineral surfaces and as a consequence govern the selectivity of the flotation process.

Froth flotation - Wikipedia

Froth flotation is a process for separating minerals from gangue by taking advantage of differences in their hydrophobicity. Hydrophobicity differences between valuable minerals and waste gangue are increased through the use of surfactants and wetting agents. The selective separation of the minerals makes processing complex (that is, mixed) ores economically feasible. The flotation process is used for the separation of a large range of sulfides, carbonates and oxides prior to further refinement. Phosphates and

Collector: Add it to the agitation tank or flotation cell with the foaming agent, while the insoluble collector (such as cresol aerofloat, white catching agent, kerosene) is often added to the grinding mill to promote its dispersion and increase the action time with minerals.

Flotation Reagent - an overview | ScienceDirect Topics

Coal flotation reagents The use of liquid hydrocarbons (‘oils’) as collectors in flotation of coal is characteristic for the group of inherently hydrophobic minerals (graphite, sulfur, molybdenite, talc, coals are classified in this group). Since oily collectors are water-insoluble, they must be dispersed in water to form an emulsion.

A line diagram of a column flotation cell. The ‘Mocrocel’ column flotation developed at the Virginia Polytechnique and State University uses an inline mixture to generate fine bubbles in the column. In this column, a part of the reject stream is passed through the inline mixture along with the frother and air to generate fine bubbles.

The Importance of pH in Flotation

In flotation, pH control is a vital method to control selective mineral separation. A standard depressant that is used is an Alkali. An Alkali is any substance that when mixed with Acid will neutralize each other and form a new chemical substance called a BASE. This is very important. The ore may be either alkaline or Acidic. To have a positive control over flotation, it is necessary to be ...

The one major advancement has been the use of Column Flotation as a cleaner float cell in the copper industry (and a few other industries). It produces a cleaner product, and is more efficient as a cleaner cell, generally, than conventional flotation cells. The column flotation cells began to appear in plants in the late 1970's and into the 1980's and were widely accepted by the 1990's. The ...
