1212 MINERALOGICAL NOTES

Flotation separation of feldspars from quartz was first accomplished in 1936 (Ladoo and Meyers, 1951, p. 216) and has been used commercial-ly for many years. For example, the feldspar plant at Kona, North Caro-lina produced from alaskite ore a pottery spar with a maximum amount of 5 percent q:uartz (Lutzen, 1953, Table 1). However, despite its ...

Developing Effective Separation of Feldspar and Quartz ...

Previously, a selective flotation separation of feldspar in the presence of HF was proposed by Fuerstenau et al. [] in an acidic environment (pH = 2.1) was suggested that the HF method can achieve a good separation of feldspar and quartz with a high grade of feldspar and a high-quality quartz [].However, there is a large amount of chemical activator (HF or NaF) in the flotation system, as ...

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. A rotary dryer is then used to reduce the moisture content to 1 percent or less.
