The Amenability of the Jameson Cell for Pre-Rougher

The rougher concentrate is typically of relatively low grade that often needs regrinding to improve liberation before being upgraded to a saleable concentrate grade in subsequent cleaner stages. In practice, it is found that the flotation feed is composed of a distribution of mineral particles with various degrees of liberation.

Flotation Machines in Brazil — Columns Versus Mechanical

The role of flotation columns in comparison with conventional mechanical flotation cells is discussed under the scenario of Brazilian flotation technology. All iron ore concentrator circuits commissioned since 1990 incorporated column only flotation technology in rougher, cleaner, scavenger configuration. Columns were also added to existing circuits, especially at the cleaner stage.
