Chapter 6 CONCENTRATION O F FELDSPARS BASED ON SPECIFIC GRAVITY AND ON FLOTATION In Chapter 11, it will be shown that efficient concentration techniques are a conditio sine qua non for a quantitative analysis of the feldspar content of a large number of sediments. Consequently, any promising concentration method needs our special attention.

2012-5-15 gravity from feldspar. This distinguishing property of fine mica particles was first reported by Iverson (1932). He managed to separate mica from feldspar by tabling. Later, Adair et al. (1951) also showed the possibility of concentration of mica in the Humphrey spiral. Therefore, this method is considered as an alternative method to mica flotation.

expansion, the specific gravity of the spodumene decreases from 3.1 g/cm3 (natural α-spodumene) to around 2.4 g/ cm3 β-spodumene). After roasting, the material is cooled and then mixed with sulphuric acid (95-97%). The mixture is roasted again at about 200°C. An exothermic reaction starts at 170°C and lithium is extracted from
