AkzoNobel Surface Chemistry Flotation Mining Technology
Flotation systems for removing silica from magnetite ores have to be designed differently compared to the systems for treatment of hematite ore. There are several reasons for this but in all magnetite flotation, the collector must have the capability to float mixed magnetitesilica grains.
Microemulsions and nanoemulsions applied to iron ore
This application is based on the ability of such systems to reduce interfacial tension, which favors their application in separation processes. In these systems, the collector was composed by alkyl ether monoamine (Flotigam EDA 174;), nbutyl alcohol, and kerosene. Corn starch with a high degree of purity was the depressant in the process.
Use of Ultrasound to Enhance Flotation Performance
an amine acetate type collector, Flotigam CA, was found as the most effective collector. At the favorable flotation conditions, the ash of the oil shale was reduced from 34.76% to 16.81% at 84.10% combustible recovery. Flotation results after ultrasonic pretreatment of the oil shale at different power levels are given in Figure 4. At 20 and
Effects of alkyl ether amine and calcium ions on fine
In this study, alkyl ether amine (Flotigam EDAC from Clariant) was used as a collector for the flotation of quartz. It shows better collectability for the flotation of quartz at about pH 10.0 (177;0.2).
