other gangue minerals from feldspar was discussed by Heyes et al. in 2012[9]. However, a HF-free flotation process using a mixture of the cationic and anionic collectors for the separation of feldspar from sand was described by Katayanagi [4] and the process was reported to be applied in industrial practice [2] [4].

Then hydrofluoric acid amine flotation is used to separate feldspar from quartz. Filtering-Drying. The spodumene concentrate is discharged at the tailing discharge of the flotation machine and is ready for final processing. The spodumene pulp contains approximately 20% solids and must be dewatered before filtration to reduce the volume of filtrate.

CaCl 2 produced in the previous process was treated with K-feldspar. The aim was to replace calcium ions with potassium at temperatures above the melting point of the feldspar sample. The feldspar—CaCl 2 ratio was kept constant at 1:1.5, and the mixture was roasted at different roasting temperatures (800, 850, 900, and 950 °C) for an hour

From mineral processing point of view, it is important to identify the ore and gangue minerals (mineralogical study), their textural relationship (grain size, grain boundary relationship etc.). The mineralogical study also helps in the modal distribution of ore and gangue minerals which decides the grade of ore.

Metamorphism: A Process of Change 1 Metamorphic rock forms from a pre-existing rock or protolith. During metamorphism, new minerals grow at the expense of old minerals, and/or the shape, size, and arrangement of grains in the rock may change. Changes occur in the solid state because melting doesn t occur.
