Also, if little or no mica is present, the first flotation step may be bypassed. Sometimes the final flotation stage is omitted, leaving a feldspar-silica mixture (often referred to as sandspar), which is usually used in glassmaking. From the completed flotation process, the feldspar float concentrate is dewatered to 5 to 9 percent moisture.

Feldspar is a common occurrence in spodumene ores, and has applications in glass making. K-feldspar is a key component in the manufacturing of ceramic materials. Froth flotation is the main method used for the recovery of feldspar from lithium ores because its flotation properties are well understood (Fuerstenau and Pradip, 2005). …
Amine–oleate interactions in feldspar flotation
Flotation tests show that the amine concentration ought to be kept lower than 1.47 × 10 −5 mol/l (≈5 ppm) to prevent feldspar loss during metal-oxides flotation stage and hence dewatering/washing operation after mica flotation seems to be a crucial step. Feldspar recovery in the concentrate, being 86.67% without dewatering/washing ...

Green and sustainable recovery of feldspar and quartz from …
This work explored a clean flotation process for separating mica, quartz-feldspar from granite tailings. 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 …

Abstract The flotation process and magnetic separation are the most common methods for feldspar beneficiation containing approximately 0.4% Fe2O3 and 0.04% TiO2. A model MIH (13) 111-5 Induced Roll dry high-intensity magnetic separator was used in this investigation to produce high-quality feldspar concentrate, and …
Processing Spodumene by Froth Flotation for Lithium Extraction
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.
