A well-known method for the concentration of feldspars is based on the specific gravity of these minerals. In the following sections we will deal with the specific gravity concentration of feldspars in detail. The other methods des cribed before will not be discussed any further.

K-feldspar and Na-feldspar exhibit similar mineralogical, chemical and surface properties. Froth flotation is known to be the only technique to enable their separation. Our earlier studies revealed a good selectivity in the presence of K+ and to a larger extent with Na+ ions. In this context, in order to further identify the role of Na+ ions in the selective separation of these …

application.Albite is generally separated from iron and quartz by physical separation and flotation techniques. Iron-bearingminerals could be separated using acid leaching and/ or floatation using sulfonate or fatty acid type collectors. The presence of slimes in feldspar flotation resulted in low separation efficiency [Hosseini et al., 2016].

Heavy liquid density separation is commonly utilised in isolating specific minerals from bulk sediment for luminescence dating. K-feldspars are commonly separated from other minerals by isolating the <2.58 g cm −3 fraction which yields infrared stimulated luminescence (IRSL) signals conducive to dating. However, initial measurements of the IRSL and …

However, the separation schemes currently being used industrially are largely the same as those first proposed 60 years ago because the processes used are very efficient. The general circuit for commercial separation of feldspar consists of three sequential stages of flotation, all of which are carried out in an acid medium.

Plagioclase feldspars are divided into six different species based on the chemistry of the material (see figure 1). Albite is the sodium-rich end member, anorthite the calcium-rich end member. The chemistry along this line (known as a solid-solution series) is infinitely variable, meaning an individual specimen may potentially fall anywhere along
