Column flotation provides excellent recovery of ultrafine coal while producing low ash content concentrates. However, column flotation is not efficient for treating fine coal containing significant amounts of mixed-phase particles. Fortunately, enhanced gravity separation has proved to have the ability to treat the mixed-phased particles more effectively.
The Eriez Flotation Division has supplied more than 900 flotation columns throughput the world in mineral concentrating and purification applications that include iron ore, base-metals, gold, industrial minerals, fertilizers (phosphate and potash), energy (coal and oil-sands) and specialty applications such as oil/water separation.
Froth flotation is a highly versatile method for physically separating particles based on differences in the ability of air bubbles to selectively adhere to specific mineral surfaces in a mineral/water slurry.
Lower Flotation Rate Constant in Plant Columns. The rate constant (k) for the valuable mineral is a key parameter for a proper scale-up, and ideally the value measured in the 50 mm column should be the k value likely to exist in the future plant column. However, the values in the plant columns are lower, at similar air addition and bias rates.

14 Shuai Li et al.: Preliminary Study on Floatation of Flotation Column for Ertang Coal Slime Table 4 shows that when the amount of collector is constant (200 g / t), with the increase of the amount of foaming agent, the yield of clean coal and flotation optimization index are increased.
industry due to the large capital costs of multi-stage circuits. Consequently, column flotation has become the preferred alternative to multi-stage cleaning for the coal industry. Column cells are able to significantly reduce the entrainment problem through the addition of a counter-current flow of wash water to the top of the froth. Studies
The test data showed that column cell technology was superior to single- and multi-stage conventional flotation circuits in terms of fine coal recovery and product grade. In light of these promising results, a full-scale column flotation circuit was designed, installed and commissioned at the Middle pork plant.
Column flotation testing was conducted on the flotation feed slurry obtained from a preparation plant located in the southern Illinois coal basin using three different bubble generating devices, static sparger, gas saver and foam jet.
In this article, the prospective aspects of the column floatation as a coal cleaning process at a coal field is described putting special emphasis on the possible application in under developing countries. The floatation mechanisms are also illustrated on the basis of recent data of column floatation.
