For mica flotation, sodium carbonate (Na 2 CO 3) was used as pH adjuster, and sodium oleate/octanol with mass ratio 9/1 (NaOT) and dodecylamine (DDA) were used as mixed collectors. Subsequently, quartz-feldspar separation was carried out using sodium hydroxide (NaOH) as pH adjuster, magnesium chloride (MgCl 2 ) as activator, …

The flotation tests demonstrated that the best process conditions for the flotation of iron-bearing minerals, such as mica, from quartz and feldspar are a pH of …

Flotation experiments performed on a quartz-feldspar mixture demonstrate that quartz can be floated selectively from feldspars in diluted solutions of hydrofluoric acid (HF) simply by the aid of a frother. High grades and good recoveries were obtained for both quartz and feldspars. A feldspar concentrate of 99.9% at a recovery of 95.6% was ...

The selectivity in flotation separation of spodumene from other pegmatic aluminosilicates such as feldspar and mica, using a single fatty acid anionic collector, is found to be very difficult.

Moreover, the effects of these ions on the flotation of feldspar and quartz were different from those on the flotation of spodumene. Download : Download high-res image (447KB) ...

Much of the flotation technique developed in separation of feldspar from quartz and mica is applicable. In general, beryl will concentrate with the feldspar flotation product. Depressing the feldspar and reflotation of the beryl into a high grade marketable concentrate (at least 8.0% BeO) is the usual procedure.

The following combination, for a North Carolina deposit, involves two steps of flotation. Gangue minerals such as mica, feldspar, and quartz are first floated after grinding the ore and de-sliming by treatment with a cationic collector in alkaline circuit, and with starch or dextrine, to depress spodumene and iron minerals.

In this paper, a complete scheme aimed at improving the flotation performance of spodumene and comprehensively recycling mica and feldspar from …
