Problems solved by technology

[0002] At present, the recovery of antimony sulfide and gold-bearing sulfide ores at home and abroad generally adopts the priority flotation process, that is, the antimony sulfide minerals are preferentially flotation under acidic or neutral conditions, and then the gold-containing sulfide minerals are flotation. Both antimony and gold minerals have been effectively recovered, but when recovering antimony minerals, some gold-bearing minerals with better floatability also entered the antimony concentrate, and at the same time, some antimony minerals with poor floatability also entered the gold concentrate, resulting in The recovery rate of antimony gold is not high and the impurity elements in the concentrate exceed the standard, which increases the cost of subsequent smelting

Embodiment 1

[0017] An example of the preparation method of antimony-gold mineral collector of the present invention, comprises the following steps:

[0018] (1) sodium sulfide is mixed with 30% solution 1 by mass ratio;

[0019] (2) Add 35% butanol or isobutanol and thiamine into solution 1 at a mass ratio of 1:2, and stir at a temperature of 80°C until dissolved to obtain solution 2;

[0020] (3) Add oleum into solution 2 at a mass ratio of 1:1, react for 2 hours at 3Mpa, then evaporate the water to dryness at 50°C, and the obtained solid agent is the antimony-gold mineral trap. Receiver.

Embodiment 2

[0022] Another example of the preparation method of antimony-gold mineral collector of the present invention, comprises the following steps:

[0023] (1) sodium sulfide is mixed with 30% solution 1 by mass ratio;

[0024] (2) Add 40% butanol or isobutanol and thiamine into solution 1 at a mass ratio of 2:5, and stir at a temperature of 85°C until dissolved to obtain solution 2;

[0025] (3) Then add oleum into solution 2 at a mass ratio of 2:3, react for 3 hours under the condition of 3.5Mpa, then evaporate the water to dryness at 60°C, and the obtained solid agent is the antimony gold Mineral collectors.

Embodiment 3

[0027] This embodiment is an application example of the antimony-gold mineral collector in the flotation of antimony-gold minerals.

[0028] 1. Mineral raw materials:

[0029] The mineral raw materials used are antimony sulfide and gold-bearing sulfide ore, in which the content of antimony is 0.85%, the content of arsenic is 1.34%, the content of sulfur is 8.56%, and the content of gold is 3.15g / t. The phase analysis shows that the antimony minerals in the ore are as follows: Mainly stibnite, there is also a small amount of antimonite, stibnite and antimony ocher, the gold-bearing minerals are mainly pyrite and arsenopyrite; the gangue minerals are mainly silica and carbonate calcium magnesium minerals and a small amount of mica .

[0030] 2. Chemical system and operating conditions: Grind the ore until the mineral monomers are decomposed, add sulfuric acid to adjust the pH of the slurry to 6-6.5, then add 200g / t of water glass as an inhibitor, add 50g / t of lead nitrate and 6...

Abstract

The invention discloses a method for preparing an antimony gold ore collecting agent. The method for preparing the antimony gold ore collecting agent comprises the following steps that (1) sodium sulfide is prepared into a solution 1 with the mass ratio being 30%; (2) 35%-40% of butanol or isobutanol and thiamine ester are added into the solution 1 according to the mass ratio of 1-2:2-5, stirring is conducted under the temperature of 80-85 DEG C till dissolution, and a solution 2 is obtained; and (3) fuming sulphuric acid is added into the solution according to the mass ratio of 1-2:1-3, a reaction is conducted under the 3-3.5 MPa condition for 2-3 hours, moisture is removed through drying at the temperature of 50-60 DEG C, and an obtained solid agent is the antimony gold ore collecting agent.
