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 ...

Abstract

The invention provides a collector for sorting monazite and ilmenite and its use method. The collector includes 10-15 parts of tall oil, 25-35 parts of oxidized paraffin soap, and 40-50 parts of palm oil. 10-15 parts of sodium fatty acid methyl ester sulfonate, 10-15 parts of sodium hydroxide; microwave pretreatment of tall oil, oxidized paraffin soap, palm oil and sodium fatty acid methyl ester sulfonate, and then 70-85 ℃ Mix and stir; then add sodium hydroxide and mix at 85-100°C to obtain the collector. The invention adopts a novel microwave pre-activated pretreatment method on the equipment, which replaces the direct reactor reaction, reduces the saponification time, reduces the production cost, and has better harvesting effect. Using the collector of the present invention can improve the comprehensive grade P of monazite concentrate to more than 10.29%, the operational recovery rate P can be raised to more than 88.03%, and the comprehensive grade P of ilmenite ore TiO 2 Increase to more than 50.00%, operating recovery rate TiO 2 Increase to more than 96.22%, has very good economic benefits.

Description

technical field [0001] The invention belongs to the technical field of mineral processing, in particular to a mineral processing process for separating monazite and ilmenite in seaside placer, in particular to a collector for separating monazite and ilmenite and a method for using the same. Background technique [0002] Seaside placer is a very important deposit in the mineral resources of Hainan and Guangxi in my country. In addition to rich ilmenite reserves, this kind of deposit is accompanied by zircon and monazite with huge reserves. There are many such resources abroad, such as Australia, Malaysia, the United States, South Africa, Brazil, India, Mozambique, etc. [0003] In the process of magnetic separation of ilmenite, monazite often contains a small amount of monazite due to its weak magnetic properties. Since monazite contains P, the content of P in ilmenite concentrate is required to be 0.1 % or less, therefore, the fine quality of ilmenite declines, and the econ...
