Beneficiation of feldspar ore for application in the ...

2015-3-1  Both feldspar and quartz in amine flotation and in the absence of HF need not be floated at pH less than 4. However, in the presence of HF feldspar is floated at pH 2–3 while quartz does not float. Feldspar was floated using tallow amine acetate at a pH of 2–3 ( Abdel-Khalek et al., 1994 , Sekulic et al., 2004 ), with a pulp density of 25%.
