Adsorption and flotation behavior of manganese

1983-9-1  Flotation experiments were conducted with a modified version of the Hallimond tube (Fuerstenau et al., 1957), using a 100 X 150 mesh size frac- tion of manganese dioxide at 1% solids. A flotation time of 2 minutes at a nitrogen flowrate of 45 ml/minute was selected for these experiments.

Flotation Manganese Ore Froth Flotation (Sulphide

2021-8-1  Haven't seen any pyrolusite flotation done, however no doubt possible based on other 'oxide' flotation systems. Just need to identify the surface charge (IEP, ZPC) of the manganese mineral as a function of pH, look up the surface charge of the gangue minerals at the various pHs and then select your collector(s) (anionic vs. cationic).

On using electrokinetics to interpret the flotation

1999-9-1  Relative flotation recovery of manganese dioxide as a function of pH at various concentrations of sodium oleate. The major pH region in which oleate can bring about flotation was first observed by Polkin and Najfonow (1965) who reported that a wide variety of oxide and silicate minerals respond quite similarly to flotation with oleate collector in the pH range of 5 to 10.

Flotation and sintering of synthetic manganese

The process includes the steps of reacting the manganese in the nodules to yield a carbonate and subjecting the manganese carbonate to flotation. The manganese carbonate froth is collected from the top of a flotation cell, is dried to produce a manganese concentrate, and is sintered to produce a synthetic manganese oxide.

Applicability of Hydrated Iron(III) Oxide and

The applicability of tetramethylenedithiocarbamate (TMDTC−) and hexamethylenedithiocarbamate (HMDTC−) for colloid flotation separation of manganese in traces from fresh (spring, well and tap) water was studied. The experimental conditions for the successful manganese separation and preconcentration before electrothermal atomic absorption spectrometric (ETAAS) determination were optimised.
