Embodiment 1
[0015] Example 1. A colloidal positive and negative flotation process, the silicon-calcium colloidal ore is crushed and ground to dissociate the constituent mineral monomers, and water is added to adjust the slurry to a concentration of 20%, and then flow into the stirring tank, and then Add regulator water glass and positive flotation collector to the slurry to adjust the slurry, the material after slurry adjustment enters the positive flotation system for positive flotation, the product in the tank is positive flotation tailings, discharged and stacked, and positive flotation The foam product enters the reverse flotation stirring tank, and the reverse flotation regulator, inorganic acid and reverse flotation collector are added to it for slurry adjustment, and the material after slurry adjustment enters the reverse flotation system for carbonate gangue mineral reaction. Flotation, the obtained foam product is reverse flotation tailings, discharged and stacked, the product in...
Embodiment 2
[0016] Example 2. A kind of colloid phosphate positive and negative flotation process, the siliceous calcium colloid phosphate ore is crushed and ground to dissociate the constituent mineral monomers, and water is added to adjust the slurry to a concentration of 50%, and then flow into the stirring tank, and then Add regulator water glass and positive flotation collector to the slurry to adjust the slurry, the material after slurry adjustment enters the positive flotation system for positive flotation, the product in the tank is positive flotation tailings, discharged and stacked, and positive flotation The foam product enters the reverse flotation stirring tank, and the reverse flotation regulator, inorganic acid and reverse flotation collector are added to it for slurry adjustment, and the material after slurry adjustment enters the reverse flotation system for carbonate gangue mineral reaction. Flotation, the obtained foam product is reverse flotation tailings, discharged a...
Embodiment 3
[0017] Example 3. A collophosite positive and negative flotation process, the siliceous calcareous collophosite ore is crushed and ground to dissociate the mineral monomers, and water is added to adjust the pulp to a concentration of 30%, and then flow into the stirring tank, and then Add regulator water glass and positive flotation collector to the slurry to adjust the slurry, the material after slurry adjustment enters the positive flotation system for positive flotation, the product in the tank is positive flotation tailings, discharged and stacked, and positive flotation The foam product enters the reverse flotation stirring tank, and the reverse flotation regulator, inorganic acid and reverse flotation collector are added to it for slurry adjustment, and the material after slurry adjustment enters the reverse flotation system for carbonate gangue mineral reaction. Flotation, the obtained foam product is reverse flotation tailings, discharged and stacked, the product in th...
