of wet tailings dams, the processing of copper ores at coarser particle sizes has become a focal point for the industry. Sulphide flotation using the Eriez HydroFloatTM is one of the emergent technologies that sits under this umbrella of coarse pre-concentration. It has been demonstrated through numerous lab and pilot scale
REPROCESSING OF THE OLD FLOTATION TAILINGS …
Flotation tailings reprocessing consisted of acid leaching followed by re-flotation of the leach residue. Leaching of the tailings resulted in leach liquors containing Cu2+ ions from 50 to 580 ppm. The average copper removal degree in the leaching stage was 70%.

Flotation tailings were successfully flocculated in the presence of cationic polyacrylamide and silica gel. The effects of various parameters such as polymer weight, charge density, and pH on the...
Tailings - Wikipedia
Tailings are the materials left over after the process of separating the valuable fraction from the uneconomic fraction of an ore. Tailings are distinct from overburden, which is the waste rock or other material that overlies an ore or mineral body and is displaced during mining without being processed. The extraction of minerals from ore can be done two ways: placer mining, which uses water and gravity to …

A dip sampler is required to sample tailings of an individual flotation cell. The sampler is used to collect slurry near the cell bottom (near the tails port). After the sampler is lowered to the desired position, the sampler lid is quickly opened by pulling a rope. The length of the sampler can be adjusted according to the desired sampling depth.

Tailings Archives | Mineral Processing & Metallurgy
Fine material, such as flotation tailings, normally does not require size reduction prior to pyrite flotation. On the other hand, coarse tailings such as those produced from certain gravity concentrating operations, must be ground to provide a product suitable for flotation. This study deals with various types of tailings and subsequent treatment methods. FINE TAILINGS
