In the first step of PTMS magnetic separator under the condition of neutral pH value, the material containing potassium alspar is crushed and ground to a particle size of -0.074mm, accounting for 60%. In step 1, the concentration of solid phase in potassium-bearing albite pulp is 30-45wt %. In step 2, the amount of modified oleic acid is 300 ~ 400g/t potassium-bearing feldspar material, and the amount of petroleum sulfonate is 400 ~ 500g/t potassium-bearing feldspar material; Among them, the modified oleic acid by the mass ratio of 90% oleic acid, 3% alcohol, 3% diesel oil, 4% tween 80 mixing at room temperature.
In the third step of PTMS magnetic separator under the condition of neutral pH value, the amount of sodium oleate is 1000 ~ 1600g/t potassium-bearing soalspar material; The activator is at least one of dodecylamine, octadecylamine and ether amine, and the total amount of activator is 140 ~ 220g/t potassium-bearing feldspar material; The inhibitor uses at least one of sodium hexametaphosphate and sodium silicate, and the total dosage of the inhibitor is 280 ~ 450g/t potassium-bearing feldspar material. In step 4, the amount of sodium oleate is 500 ~ 800g/t potassium-bearing feldspar materials; The activator is at least one of dodecylamine, octadecylamine and ether amine, and the total amount of activator is 70 ~ 110g/t potassium sodium feldspar material; The inhibitor uses at least one of sodium hexametaphosphate and sodium silicate, and the total dosage of the inhibitor is 140 ~ 220g/t potassium-containing albite material.
In step 5, the inhibitor uses at least one of sodium hexametaphosphate and sodium silicate, and the total dosage of the inhibitor is 30 ~ 50g/t potassium-bearing albite material. At least one rough separation of PTMS magnetic separator is performed in step 3. In step 4, at least two sweeps are performed, and each sweep returns the selected ore to the previous operation in sequence. In step 5, at least one cleaning of PTMS magnetic separator is performed, and the cleaned middles are returned to the upper section in sequence.
