Column Circuits

Column cells can be used to perform many functions. These include separation within a grinding circuit (unit cell), as an initial (primary or rougher) or scavenging separator whose purpose is maximum recovery of material, or as a Rnal separator (cleaner or recleaner) used to produce a pure product. They can also be used to process bleed streams from other processes. There are many examples of column usage, including base metal and industrial mineral separation, iron ore purification, coal cleaning, solvent extraction and oil-water separation, paint recovery and newspaper de-inking. In addition, columns can be used to remove hydrophobic substances, or materials dissolvable in hydrophobic liquids, from water or soils. Examples are DDT, polycyclic aromatic hydrocarbons (PAHs) or other dangerous chemicals, oil production from tar sands, or the purification or removal of algae or bacteria from cultures. All of these separations fall into three categories: solid-solid, solid-liquid and liquid-liquid separations.
