Embodiment 1
[0032] The preparation of embodiment 1 collector
[0033] (1) By weight, get 10 parts of tall oil, 25 parts of oxidized paraffin wax soap, 50 parts of palm oil, 15 parts of sodium fatty acid methyl ester sulfonate, carry out microwave pretreatment 10 minutes, microwave power 10kg / kw microwave power, microwave Frequency 2000MH Z . Then mix and stir in the reaction kettle at 85°C.
[0034] (2) Add 10 parts of sodium hydroxide flakes again, and saponify under the condition of 100°C for 1.5 hours.
Embodiment 2
[0035] The preparation of embodiment 2 collector
[0036] (1) By weight, get 25 parts of tall oil, 35 parts of oxidized paraffin wax soap, 40 parts of palm oil, 10 parts of sodium fatty acid methyl ester sulfonate, carry out microwave pretreatment 5 minutes, microwave power 5kg / kw microwave power, microwave Frequency 3000MH Z . Then mix and stir in the reaction kettle at 70°C.
[0037] (2) Add 15 parts of sodium hydroxide flakes again, and saponify under the condition of 85°C for 2.5 hours.
Embodiment 3
[0038] The flotation process of embodiment 3 monazite, ilmenite
[0039] The raw material is Mozambique ilmenite rough concentrate from Hainan Haituo Mining Co., Ltd., and the rough concentrate contains TiO 2 50.26%, with P 0.98%. Among them, ilmenite is the main component, and there are also some monazite, zircon and a small amount of garnet.
[0040] Flotation adopts a rough selection and a selective method. Flotation flow chart see figure 1 .
[0041] (1) rough selection
[0042] The roughing condition is: flotation concentration 40~60%, flotation time 15min, collector is the collector of embodiment 1, and consumption is 250g / t; Inhibitor is water glass, and consumption is 500g / t; Activator It is copper sulfate, the dosage is 150g / t; the foaming agent is 2# oil, the dosage is 40g / t; monazite roughing concentrate and tailings are obtained.
[0043] (2) Featured
[0044] The monazite is roughed and concentrated and then refined. The selected conditions are: flotation ...
