• A novel approach for flotation recovery of spodumene, mica ...

    Feb 10, 2018· HF is traditionally used as an activator in highly acidic conditions during the flotation of feldspar from quartz (Larsen and Kleiv, 2016). However, in the flotation flowsheet, the usage of HF is replaced by H 2 SO 4 in consideration of environmental and health hazards. Table 10 contains the results of the locked test for the recycling of feldspar.

    Mar 01, 2015· 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 ( AbdelKhalek et al., 1994 , Sekulic et al., 2004 ), with a pulp density of 25%.
