[0023] Through the setting of stirring components, heating components and air inlet components, the zinc-sulfur mixed concentrate can be floated and separated by lime or a small amount of cyanide method and heating method. The multi-stage separation design has high separation efficiency. Figure 1-4 As shown, the multi-stage zinc-sulfur separation flotation device described in the present invention includes a box body 1, a heating assembly 2 is provided inside the box body 1, and the heating assembly 2 includes a heating plate 201 fixed to the inside of the box body 1 by bolts. Electric heating wires 202 are fixed to the inside of the heating plate 201 by bolts at equal intervals. A stirring assembly 3 is provided on the top of the box body 1, and a structural cover 5 is welded to one end of the box body 1.

[0024] An air intake assembly 4 is provided on one side of the box body 1, and the air intake assembly 4 includes an air pump 401 installed on one side of the box body 1 through a mounting bracket. The air outlet end of the air pump 401 is connected to a connecting pipe 403 through a pipe joint. One end of the connecting pipe 403 located inside the box body 1 is connected to an air collecting pipe 404 through a threaded groove. The top of the air collecting pipe 404 is equidistantly connected to a one-way valve 405 through a pipe, and the top of the one-way valve 405 is connected to a nozzle 406 through a threaded groove.

[0025] During use, the zinc-sulfur mixed concentrate and lime or a small amount of cyanide in the box body 1 are stirred and mixed by the stirring component 3, and flotation separation by lime or a small amount of cyanide method can be performed. The sulfur mixed concentrate in the box body 1 is heated by the temperature controller 6 and the heating component 2, and flotation separation by heating method can be performed.

[0026] For example, Figure 2 As shown, the present invention further includes that the stirring assembly 3 includes a top plate 301 fixed to the top of the box body 1 by bolts, and a driving motor 302 is installed on the top of the top plate 301 through a mounting bracket.

[0027] When in use, the driving motor 302 is used to drive the connecting rod 303 to rotate.

[0028] For example, Figure 2 As shown, the present invention further includes that the output shaft of the driving motor 302 located inside the box body 1 is connected to a connecting rod 303 through a connecting sleeve, and stirring rods 304 are equidistantly welded to the outside of the connecting rod 303 .

[0029] When in use, the connecting rod 303 rotates to stir and mix the zinc-sulfur mixed concentrate and lime or a small amount of cyanide in the box body 1 through the stirring rod 304.

[0030] For example, Figure 1 、 Figure 2 As shown, the utility model also includes that a thermostat 6 is installed at one end of the box body 1 through a mounting seat, the detection end of the thermostat 6 is located inside the box body 1, the current output end of the thermostat 6 is electrically connected to the current input end of the electric heating wire 202 through a power line, and the interior of the heating plate 201 located outside the electric heating wire 202 is filled with magnesium oxide powder 203.

[0031] When in use, the temperature controller 6 is used to control the heating of the electric heating wire 202 and its heating temperature, and the magnesium oxide powder 203 plays the role of insulation and heat conduction.

[0032] For example, Figure 1 、 Figure 2 As shown, the present invention further includes that one end of the box body 1 is connected to a drain valve 7 through a pipeline, and a discharge pipe 8 is welded to the bottom of the structural cover 5.

[0033] When in use, the drain valve 7 is opened to allow the liquid in the box body 1 to be discharged, and the sphalerite entering the structural cover 5 flows out from the discharge pipe 8.

[0035] When in use, the filter cover 402 can prevent external dust and the like from being drawn into the air collecting pipe 404 by the air pump 401 .

[0036] When the utility model is used, a person connects the device to an external power source using a power cord, pours the finely ground zinc-sulfur mixed concentrate into the box 1, and adds a certain amount of water, lime or a small amount of cyanide into the box 1. The driving motor 302 is turned on to drive the connecting rod 303 and the connecting rods 303 outside it to rotate at high speed, so that the lime or a small amount of cyanide in the box 1 can be mixed with the sulfur mixed concentrate, and flotation separation is performed by the lime or a small amount of cyanide method;

[0037] The personnel controls the heating of the electric heating wire 202 through the thermostat 6. The magnesium oxide powder 203 absorbs the heat of the electric heating wire 202 and conducts it to the heating plate 201, heating the sulfur mixed concentrate in the box 1. After heating, the stirring rod 304 stirs the ore, which reduces the floatability of the oxide on the surface of the pyrite. However, the sphalerite still remains floatable under this condition and is separated by flotation through the heating method.

[0038] Turn on the air pump 401 to draw external air into the gas collecting pipe 404 through the connecting pipe 403, and then spray it into the box 1 from the nozzle 406 through the one-way valve 405. The gas enters the box 1 and floats upward, which can float the sphalerite in the box 1. The sphalerite after floating overflows into the structural cover 5 and flows out through the discharge pipe 8.

Those skilled in the art should understand that the present invention is not limited to the above embodiments.
