Flotation Reagent - an overview ScienceDirect Topics

The column flotation cell which has achieved success in the mineral industry was introduced to the coal industry in the 1990s. The machine consists of a long (∼6 m) vertical tube ranging from 2.4 to 3.0 m in diameter. Figure 3 shows a sketch of the column flotation machine. The feed (coal slurry containing flotation reagents) to the column is introduced at about the 5-m level.

Mining Floatation Chemicals YX - mining reagent

The flotation process involves the process of aeration of minerals in the presence of flotation reagents that help in the attachments of air bubbles to the selected minerals. Some of the mining flotation chemicals are dispersants, activators, collectors, flocculants, and depressants. The use of froth floatation has improved the recovery of valuable minerals.

The Importance of pH in Flotation

21/10/2020  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 ...

Several-time dosing: Add the flotation reagents in several times along roughing, concentrating and scavenging. Generally, add 60%~70% of the total amount before the flotation stage, and the rest of reagents is added to the appropriate locations in batches. Application: Oxidizing, labile and reactive reagents, such as xanthate, sulfur dioxide gas; Reagents that are insoluble in water and can be ...

Eight Factors Affecting the Flotation Process - Xinhai

Different reagents also have different effects in the flotation process (e.g., collecting, foaming and regulating effect). even if it is the same kind of reagent, two or more kinds of reagents are often used. If collecting agent is used in the production process. For example, the mixed reagents are better than the single reagent when the collector is used. For the gold extraction, the recovery ...

5 Factors Affecting Silica Sand Flotation - Mining-pedia

Flotation is one of the commonly used methods for silica sand beneficiation. It is mainly used to remove mica and feldspar minerals that are symbiotic with silica sand. However, in the actual production process, the flotation process will be affected by many factors, including: feed size, slurry temperature, slurry liquid chemical composition, flotation reagents and other flotation conditions.

Kinetics of flotation - CONCENTRATION OF MINERALS

Flotation kinetics (from the Greek Kinētikós - driving) is studying the regularities of flotation process at the time, the rate and the flotation mechanism. Kinetics of flotation reflects the flotation results in variable states and is characterized by dependency of the recovery R of floatable mineral in concentrate from time t, i.e. R = f (t).It allows a quantitative description of the ...
