IMPACT OF THE FLOTATION TAILING DUMPS ON THE LIVING ...

from the Flotation Plant with flotation tailings, the lake is also filled with pure water from the precipitation within the basin of flotation tailing dumps (rain and snow melting). The leachate from tailing dump is col-lected in front of the protective dam over drainage system and returned back in the lake. Water inflow through dam is con-

REPROCESSING OF THE OLD FLOTATION TAILINGS DEPOSITED

The tailings contain 60 to 70% of SiO2, 10 to 17% of Al2O3and pyrite 5 to 8%. 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.

Flotation consists of various stages producing a PGMs concentrate which is then further processed at the Smelter. The tailings stream comprises materials from five main sources, namely the Merensky Plant, the uG2 Plant, the Mill Float 2 (MF2) Plant, the Slag Plant and the Tailings recovery Plant (TrP).

However, such pilot tests may not be an exact representative of the tailings that will be produced from the full scale plant. This means that the final design of any tailings facility is always provisional and must be ...

Tailingsfo What Are Tailings? - Their nature and

The five basic types of reagent used in froth flotation recovery include collectors, frothers, depressants, activators and modifiers. When designing the processing plant, the types and quantities of reagents used should be considered together with any depressing requirements to lessen environmental impacts in the tailings streams (Ritcey 1989).

05/01/2021  It is important to note that until the 1980s, mines such as Casapalca, Huarochiri, Peru, operated with conventional selective flotation grinding as coarse as 40%—200 mesh; fine grinding (70%—200 mesh) increased recovery by no more than 5%, while coarse tailings availability for dam dike and mine backfilling decreased dramatically. To place fine tailings underground, a paste fill plant was ...

Flotation stabilization and optimization - SAIMM

The control of flotation plants is by no means trivial. Flotation is one of the most interactive minerals’ processing operations. The interactive nature of flotation circuits results in oscillations of levels and hence of grades and recoveries. Also, poor level setpoint tracking and disturbances have negative influences on grades and recoveries. The result is an unstable plant with limited ...

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 ...
