Embodiment 1
[0012] An example of the preparation method of the rutile collector of the present invention includes the following steps:
[0013] First, the molar ratio of o-styrene and ethanolamine = 1:1 was mixed at a temperature of 60 to 70 ℃ to obtain solution 1, and then sodium sulfide with a mass concentration of 10%: solution 1 was added to solution 1 at a mass ratio = 1:2 , Stir at 75℃ for 1 hour to prepare solution 2; then add ammonium phosphate: solution 2 to solution 2 at a mass ratio of 1:1.5 at 90℃, stir at 82℃ for 2.5 hours, and finally at 40℃ Dry under the conditions is the rutile collector.
Embodiment 2
[0015] Another example of the preparation method of the rutile collector of the present invention includes the following steps:
[0016] First, o-styrene and ethanolamine were mixed with a molar ratio of 1.5:2 at a temperature of 70℃ to obtain solution 1, and then sodium sulfide with a mass concentration of 15%: solution 1 was added to solution 1 at a mass ratio = 2:3. Stir at 80°C for 1.5 hours to prepare solution 2; then add ammonium phosphate: solution 2 to solution 2 at a mass ratio of 1:2 at 90°C, stir at 85°C for 3 hours, and finally dry at 50°C That is the rutile collector.
Embodiment 3
[0018] This embodiment is an application example of the rutile collector in the flotation of rutile ore.
[0019] 1. Mineral raw materials:
[0020] The content of rutile in the ore used is 3.24%, the content of silicon dioxide is 13.20%, the content of iron is 8.97%, and the content of aluminum is 6.87%. The phase analysis shows that in addition to rutile, there is a small amount of ilmenite; the main gangue minerals It exists in the form of silicon dioxide, garnet, mica and other aluminum-silicon minerals, and some limonite and goethite.
[0021] 2. Flotation reagents and operating conditions:
[0022] Sodium hexametaphosphate rough selection 100g / t sweep selection 50g / t selected 50g / t
[0023] Water glass rough selection 400g / t sweep selection 100g / t fine selection 200g / t
[0024] Lead nitrate coarse selection 200g / t sweep selection 100g / t
[0025] The collector is roughly selected 300g / t, sweeping 100g / t
[0026] The pH value of the pulp during flotation is 7.5-8; during the flotation...

Abstract
The invention discloses a preparing method for a rutile collecting agent. The preparing method includes the steps that firstly, o-styrene and ethanolamine are mixed at the mole ratio being (1-1.5):(1-2) under the condition that the temperature ranges from 60 DEG C to 70 DEG C, and a solution 1 is obtained; then sodium sulfide with the mass concentration ranging from 10% to 15% is added into the solution 1 to be stirred for 1 h to 1.5 h under the condition that the temperature ranges from 75 DEG C to 80 DEG C, and a solution 2 is prepared, wherein the mass ratio of the sodium sulfide to the solution 1 is (1-2):(2-3); ammonium phosphate is added into the solution 2 at the temperature being 90 DEG C and is stirred for 2.5 h to 3 h under the condition that the temperature ranges from 82 DEG C to 85 DEG C, wherein the mass ratio of the ammonium phosphate to the solution 2 is (1-2):(1.5-4); and finally, the mixture is dried under the condition that the temperature ranges from 40 DEG C to 50 DEG C, and the rutile collecting agent is obtained.
Description
1. Technical Field [0001] The invention relates to a method for preparing a rutile collector, in particular to a method for preparing a rutile collector with fine particle size, complicated intercalation relationship, and mostly alumino-silica minerals as impurity minerals. 2. Background technology [0002] Although the reserves of rutile resources in my country are relatively large, due to the low grade and fine grain size of the original ore, in addition to minerals similar to rutile minerals such as ilmenite, garnet and chlorite, vermiculite, mica, and horn Amphiboles, as well as impurity elements such as sulfur and phosphorus that affect the quality of rutile concentrates, have been a worldwide problem in beneficiation for such fine-grained rutile ore with complex intercalation relationships. If selective collectors can be used in combination with the process flow to achieve effective flotation separation of rutile, it will not only have an important impact on the development ...
