PTMS magnetic separator is used for beneficiation of potassium alspar raw ore with K2O content of 9.65%. The raw ore also contains quartz, chlorite, magnetite, limonite, hematite and other minerals.
The flotation method of POTASSIUM alspar by PTMS magnetic separator can include the following steps: Step 1 grind the potassium feldspar raw ore with k2O content of 9.65% to 60% with particle size of -0.074mm, and make potassium feldspar pulp with solid phase concentration of 40wt %.
Step 2, to step 1 potassium sodium feldspar pulp to add modified oleic acid and petroleum sodium sulfonate, modified oleic acid adding amount of 400g/t potassium feldspar material, petroleum sodium sulfonate adding amount of 500g/t potassium feldspar material, stirring for 6min, impurity removal flotation, in order to remove iron, mud impurities, so as to get the impurity removal pulp. PTMS magnetic separator can remove iron (FE2O3) inside.
