The use of a Reflux Classifier for iron ores: Assessment

01/07/2014 In the iron ore industry, the recovery of fine particles is an important concern in terms of process performance and production costs and perennial efforts are devoted to increase the efficiency in handling these fines. The Reflux Classifier (RC) is a relatively new technology that is mainly used in the coal and minerals industries. The operating principle of this system is based on three mechanisms:

Iron ore (fines) Cargo Handbook the world's largest

Iron Ore (fines) Iron ores are rocks and minerals from which metallic iron can be economically extracted. The ores are usually rich in iron oxides and vary in colour from dark grey, bright yellow, deep purple, to rusty red. The iron itself is usually found in the form of magnetite (Fe 3 O 4), hematite (Fe 2 O 3), goethite (FeO(OH)), limonite (FeO(OH).n(H 2 O)) or siderite (FeCO 3). Ores

Gravity separation of ultra-fine iron ore in the

This paper reports tests performed on an ultra-fine iron ore with nominal top size of 0.106 mm, but with 59 wt-% being below 0.038 mm in size. The REFLUX™ Classifier consists of a set of parallel inclined channels positioned above a vertical fluidised section. The Boycott effect generates a powerful throughput advantage and using narrow channels gives a high shear rate which generates a

Fortescue Metals chooses dry classification to upgrade

The high-throughput operation will remove beneficiated magnetite fines at 120-mesh, 200-mesh and 325-mesh and increase iron concentration. The company chose the Whirlwind air classifier because, says Sturtevant, “of its dry air classification process. Wet washing requires expensive capital equipment, high energy output and a high volume of water. Dry separation requires less capital

Properties and End-Use Functionality of Iron Ore

Fine iron ore can be mixed with water and a range of potential additives, and granules produced for further testing. A range of techniques has been developed to characterise the properties of the iron ore fines and the produced granules. Work is progressing to model size segregation of agglomerates down a sinter bed using discrete element modelling (DEM), with experimental validation. In this

Types of Classifiers in Mineral Processing

Spiral Classifier. In mineral processing, the Akins AKA spiral or screw Classifier has been successfully used for so many years that most mill operators are familiar with its principle and operation. This classifier embodies the simplest design, smallest number of wearing parts, and an absence of surge in the overflow. It separates coarse and fine solids, carried in liquids, with a high degree
