In Step 4, sodium oleate is used as a collector, and the dosage of sodium oleate is best 500 ~ 800g/t potassium-bearing feldspar material (that is, 500 ~ 800g of sodium oleate should be added for every 1T of potassium-bearing feldspar material). For example, the value can be 500G /t, 550g/t, 600g/t, 650g/t, 700g/t, 750g/t, 800g/t, or a specific point between the preceding values. In addition, it is better to stir the tailings of PTMS magnetic separator for 3 ~ 5min after adding sodium oleate, so that sodium oleate can play a full role.
In step 4, it is desirable to use at least one of dodecylamine, octadecylamine, or ether amine as the activator. When dodecylamine is used as the activator, the dosage of dodecylamine is best 70 ~ 110g/t potassium-bearing feldspar material (that is, 70 ~ 110g dodecylamine is added to every 1T potassium-bearing feldspar material), For example, the value can be 70G /t, 75g/t, 80g/t, 85g/t, 90g/t, 95g/t, 100g/t, 105G /t, 110g/t or a specific point between the preceding values. In addition, it is better to stir 3 ~ 5min after adding activator to the tailings of ROUGHing by PTMS magnetic separator, so that the activator can play a full role.
In step 4, it is desirable to use at least one of sodium hexametaphosphate or sodium silicate as an inhibitor. When the inhibitor uses sodium hexametaphosphate, the dosage of sodium hexametaphosphate should be 140 ~ 220g/t potassium feldspar material (that is, 140 ~ 220g of sodium hexametaphosphate should be added for every 1t potassium feldspar material). For example, the value can be 140g/t, 150g/t, 160g/t, 170g/t, 180g/t, 190g/t, 200g/t, 210g/t, 220g/t or a specific value between the preceding values. In addition, it is better to stir 3 ~ 5min after adding inhibitors to PTMS magnetic separator tailings, so that the inhibitors can play a full role.
