The effects of inorganic anions and collector's different addition orders for the flotation of silicate minerals with dode-canamine as collector

The effects of different addition orders between sodium silicate, sodium fluoride, sodium sulfide, sodium hexametaphosphate and collector for the silicate minerals’ floatation were researched in the paper. When dode-canamine was used as collector, the addition and the orders of NaF had no effect to the silicateminerals’ floatation; the silicate minerals were inhibited by odium silicate, sodium sulfide, sodiumhexametaphosphate’s addition before collector; the actions were strengthened or depredated when the reagents were added after collector.
