The K-feldspar flotation resulted in a K-feldspar concentrate of 14.3% K 2 O at 77% ...
And the flotation separation of lepidolite from quartz/feldspar can be only achieved in a high acidic environment (pH 2–3). However, the strong acidic conditions are likely to cause the high consumption of H 2 SO 4, corrosion of flotation equipment, difficult water treatment and environmental pollution. Therefore, the flotation of lepidolite ...
A method for direct float quartz from the feldspar under alkaline pH was proposed.. Effect of depressant HPS on flotation separation of quartz from feldspar was firstly studied.. When NaOL was the collector and MgCl 2 was activator, HPS was an effective feldspar depressant.. HPS was selectively adsorbed on feldspar through Al-sites on feldspar surface.

Since the density of spodumene, feldspar and quartz is close, it is hard to separate spodumene from feldspar and quartz effectively by gravity separation. Flotation is one of the most effective ways used in the industrial separation of spodumene from feldspar and quartz [4], [8], [9].
Quartz is difficult to separate by flotation due to its similar surface physicochemical properties to spodumene.. 2 mg/L pectin and 0.005 mol/L NaOL at pH 11 allowed mineral separation. • Pectin is chemically adsorbed on spodumene through –COO– and Al sites on spodumene.. Pectin pre-sorption interferes with the adsorption of NaOL by steric hindrance.
Quartz and feldspar are usually exist in symbiosis in nature, and they are difficult to be separated effectively by conventional physical methods owing to their similarities in crystal structures and surface characteristics. Flotation is the most resultful method, and especially, flotation with hydrofluoric acid (HF) is the most efficient way. Because HF may cause serious …
