2016-11-1 · 1. Introduction. Froth flotation is the selected method for the separation of quartz and feldspar. In the conventional process, feldspar is floated from quartz by using hydrofluoric acid (HF) as activator for the feldspar and a cationic collector (amine) at pH 2–3 (O’Meara, 1939).Sandvik (1979) reported that HF creates a large difference in the minerals’ zeta

Towards a new process for the flotation of quartz ...

2015-11-1 · The quartz recovery rate is substantially faster with Brij 58 (see chapter 3.4) compared to Dowfroth 400 and Flotanol C07 as there are not much quartz left in the froth after 1 min of flotation. This might have to do with the higher molecular weight of Brij 58 and the small bubble size produced by this frother.

Mechanisms of Dodecylamine Flotation of Quartz: Mineral ...

2007-4-27 · Primary monoamines have been long used and studied as flotation collectors for quartz. In the past several mechanisms have been proposed to explain the manner in which the amines adsorb onto and render the mineral hydrophobic and, thus, floatable. From past data and proposed mechanisms and reinterpreting some of the past data it appears that ...
