UTILIZAREA MAŞINILOR DE FLOTAŢIE TIP COLOANĂ LA EPURAREA APELOR UZATE INDUSTRIALE
USE OF COLUMN TYPE FLOTATION MACHINES TO CLEANING THE INDUSTRIAL WATERS

Summary/Abstract: Process waters exiting from mining, metallurgical and petroleum operations are widespread throughout the world and can become contaminated by various pollutants. Main pollutants are residual reagents, powders, chemicals, metal ions, oils, organic and some may be valuable (Au, Pt, Ag). The use of column flotation is showing a great potential due to the high throughput of modern equipment, low sludge generation and high efficiensy of the separation schemes already available. It is concluded that this process will be soon incorporated as a technology in the minerals industry to treat these wastewaters and, when possible, to recycle process water and materials.
