Flotation Iron Column

The processes of iron ore flotation being either by means of mechanical cells or columns, are fed by particles whose sizes vary 10 and 150 µm, the ultrafine particles (slimes) are removed by means of cyclone, for they affect the process in a negative way, and the top size is limited to values between 5% and 10% above 150 µm.

This work describes the concentration of iron ore slimes on a pilot scale by using a 500-mm diameter flotation column and a novel collector, which renders the use of a depressant unnecessary. The pilot column was operated in series with the industrial plant Vargem Grande 2 (Iron Quadrangle, Brazil) receiving, as feed, part of the underflow from the desliming …

Flotation Column Cell Carrying Capacity & Scale-Up Froth Depth Froth depths in industrial column installations can range from 50 cm to 2 m. The general effect of changes in froth depth are the same as in mechanical cells. In many cases, however, because of the deeper froth, the effect of changes in depth are often less noticeable with columns.

The highly competitive nature of the international iron ore market has forced producers to improve the quality of their pellets. The demand for low-acid pellets suitable for direct reduction has resulted in an increase in the number of plants utilizing reverse froth flotation for silica reduction.Column flotation is being favored for this service because of low capital and …

The typical feed to a flotation system in the iron ore industry consists of particles in the size range between 10 µm and 300 µm. The slimes fraction (<10 µm) are removed using …

This paper reviews the industrial practices and fundamental research surrounding iron ore flotation. The advantages and disadvantages of direct flotation, cationic reverse …

Column flotation is being given serious consideration/or this service due to the low capital and operating cost of the equipment and the potential of improving metallurgical perforr, mnce. This paper describes the basic procedures for examining the feasibility of column flotation for reverse silica flotation in iron ore processing plants.

Adding column cells to existing flotation lines to act as recleaners. Pilot plant results revealed that the third option provided the best combination of plant throughput and iron recovery. The flowsheet for the modified circuit is shown in Figure 1. One column has been added as a recleaner to each processing line to preserve circuit flexibility.

Our Column Flotation Cell solutions are equipped with unparalleled monitoring controls. Normally, these types of controls supervise critical operating parameters like froth depth, wash water flow control, air supply and more to ensure the …

In general, the industrial flowsheets for the beneficiation of itabirite iron ores from the Quadrilátero Ferrífero (Minas Gerais state) in Brazil involves grinding, desliming, magnetic separation and cationic reverse flotation using both mechanical and columns flotation cells. At Brazilian plants, it is estimated that Fe losses generated at the slimes stage range between …
