Specifically, in this embodiment, the refrigeration mechanism is a water bath jacket 121 sleeved on the outer wall of the liquid medicine container 120, and ice blocks can be introduced into the water bath jacket 121 to lower the temperature of the liquid medicine in the liquid medicine container 120, thereby increasing the solubility of carbon dioxide. Further, in this embodiment, be provided with intake pipe 122 in the liquid medicine container 120, the end of giving vent to anger of intake pipe 122 extends along the direction that is close to the bottom of liquid medicine container 120 for the gas that lets in can get into the bottom of liquid medicine container 120, in order to do benefit to and dissolve into more carbon dioxide in the ore dressing liquid, accelerate the liquid medicine scale deposit. Specifically, in this embodiment, compressed air is used, and the compressed air may be introduced by an external air compressor. In addition, in this embodiment, the stirring device 123 is further disposed in the liquid medicine container 120, the stirring device 123 includes a stirring motor 1231, a stirring shaft 1232 and a stirring blade 1233, wherein the stirring blade 1233 is connected to the stirring shaft 1232, the stirring motor 1231 drives the stirring shaft 1232 to rotate, and then drives the stirring blade 1233 to rotate, and the setting of the stirring device 123 makes the carbon dioxide and the liquid medicine in the liquid medicine container 120 mix more uniformly, and further accelerates the dissolution of the carbon dioxide in the liquid medicine container 120.
The dripping device 130 is used to spray the chemical solution containing a large amount of carbon dioxide dissolved in the chemical solution container 120 onto the surface of the gold ore concentrate 146 in the leaching container 140. Specifically, in the present embodiment, the dripping device 130 includes a dripping pipe 131 and a dripping nozzle 132, two ends of the dripping pipe 131 are respectively communicated with the chemical liquid container 120 and the dripping nozzle 132, and the dripping nozzle 132 is located above the stacking container 140. In this application, the speed of blocking the dripping device 130 is increased by controlling the speed of the liquid medicine in the shower pipe, the diameter of the dripping pipe 131 and the aperture of the dripping nozzle 132. Specifically, in this embodiment, the diameter of the dripping pipe 131 is 8-10mm, and the aperture of the dripping nozzle 132 is 0.5-0.7 mm. The diameter and the aperture are far smaller than the pipe diameter and the aperture used in the actual ore dressing field (the diameter of the dripping pipe 131 in the actual ore dressing field is larger than 50mm, and the aperture is larger than 1mm), so that the blocking time of the dripping device 130 after scaling is shortened.
Further, the liquid medicine in the liquid medicine container 120 flows into the stacking container 140 through the dripping device 130 without being driven by external force, and in this embodiment, the liquid medicine flows by self-gravity by adjusting the height difference between the inlet end and the outlet end of the dripping device 130.

This application is through letting in the temperature that ice water reduced the liquid medicine in to above-mentioned water bath jacket 121 for the liquid medicine can dissolve more carbon dioxide, can also let in compressed air through intake pipe 122 to the liquid medicine of liquid medicine container 120 when necessary, makes the liquid medicine and more carbon dioxide contact in order to accelerate the scale deposit. Then, the flow speed of the liquid medicine, the diameter of the dripping pipe 131 and the aperture of the dripping nozzle 132 are greatly reduced to accelerate the blocking speed of the dripping device 130, so that the blocking time of the dripping device 130 caused by the scaled liquid medicine is shortened, and the anti-scaling performance of the tested mineral separation agent can be evaluated in a short time by the device. The anti-scaling performance of the beneficiation agent can be evaluated by testing the blockage-to-death time of the spray pipeline system.
Referring to fig. 1, 2 and 3, the cascade container 140 is used for stacking the gold ore crude ore 146, and sprays the liquid medicine discharged from the dripping device 130 onto the gold ore crude ore 146, so that the liquid medicine gradually infiltrates. In this embodiment, a filtering member 141 is disposed in the stacking and leaching container 140, the filtering member 141 divides the stacking and leaching container 140 into a stacking chamber 144 and a leaching chamber 145, the stacking chamber 144 is located above the leaching chamber 145, the stacking chamber 144 is used for stacking the gold ore crude ore 146, and the leaching chamber 145 is used for containing the liquid medicine flowing through the gold ore crude ore 146. In this embodiment, the filtering member 141 includes a perforated partition 142 and a filter cloth 143 laid on the perforated partition 142, and the liquid medicine discharged from the dripping unit 130 is sprayed onto the surface of the gold ore concentrate 146 and gradually seeps downward, and then enters the seepage liquid chamber 145 through the filtering member 141.
Referring to fig. 1, the working process of the anti-scaling performance testing apparatus 100 is as follows: the beneficiation reagent and the lime are mixed in the liquid mixing container 110, stirred evenly and stood still for clarification, the clarified liquid medicine is put into the liquid medicine container 120, the stirring device 123 is started, and ice blocks are added into the water bath jacket 121 to reduce the temperature of the liquid medicine so as to increase the solubility of carbon dioxide. When necessary, compressed air is introduced through the compressed air vent pipe, so that more carbon dioxide can be dissolved in the mineral separation liquid, and scaling is accelerated. A perforated partition plate 142 is placed at the bottom of the pile-leaching container 140, filter cloth 143 is paved on the perforated partition plate 142, and gold ore raw ore 146 is piled. The dripping sprayer 130 is used for spraying the liquid medicine on the surface of the gold ore crude ore 146, and the liquid medicine gradually infiltrates. The permeate flows through the filter 141 into the permeate chamber 145. When the amount of the percolate reaches a certain amount, the centrifugal pump 202 is started, the percolate flows back to the liquid preparation container 110 through the filter 201 and the return pipe 203, and is recycled after being clarified.
Because the temperature of the liquid medicine is reduced by the water bath jacket 121, and air can be introduced into the liquid medicine by the air inlet pipe 122 in the embodiment, the dissolving concentration of carbon dioxide in the liquid medicine is higher than that of the actual ore dressing site, and the scaling probability and speed formed by the carbon dioxide and CaOH are increased; in addition, in this embodiment, by reducing the flowing speed of the liquid medicine in the dripping device 130 and reducing the pipe diameter of the dripping pipe 131 and the hole diameter of the dripping nozzle 132, the liquid medicine moves slowly in the dripping device 130, and the blocking time after the liquid medicine is scaled is shortened, so that the device can evaluate the anti-scaling performance of the tested mineral separation agent in a short time. The anti-scaling performance of the beneficiation agent can be evaluated by testing the blockage-to-death time of the spray pipeline system. Two or more sets of same devices are adopted to carry out experiments simultaneously, and the anti-scaling performance of two or more ore dressing agents can be compared.
It should be noted that, in the present application, the liquid medicine container 120 and the dripping device 130 are mainly used to implement the anti-scaling performance test, specifically, the carbon dioxide dissolution amount of the liquid medicine in the liquid medicine container 120 is increased to accelerate the scaling time of the liquid medicine, and then the blocking time of the dripping device 130 is used to determine how the anti-scaling performance of the beneficiation reagent is. The heap leaching container 140 provided in the application is mainly used for simulating the process of mineral separation in practical application, and further, the anti-scaling performance of the mineral separation agent can be further judged by the arrangement of the heap leaching container 140 and the speed of the liquid medicine seeping from the gold ore raw ore 146 to the liquid seepage cavity 145.

Because the beneficiation agent in the liquid medicine does not necessarily react completely after flowing through the gold ore raw ore 146, in the embodiment, the liquid medicine in the seepage liquid cavity 145 is filtered by the filter 201 to remove large-particle ores, and then the liquid medicine is pumped into the liquid preparation container 110 by the centrifugal pump 202 to realize the recycling of the liquid medicine, so that resources are saved, meanwhile, the scaling process is long, at least several hours are needed, if fresh liquid medicine is prepared all the time, the cost is greatly increased, the field backflow operation is simulated in the application, the liquid medicine in the seepage liquid cavity 145 is continuously refluxed into the liquid preparation container 110, the liquid medicine is recycled, the resources are saved, and meanwhile, the method is more practical.
The working process of the anti-scaling performance testing device 100 is as follows: the beneficiation reagent and the lime are mixed in the liquid mixing container 110, stirred evenly and stood still for clarification, the clarified liquid medicine is put into the liquid medicine container 120, the stirring device 123 is started, and ice blocks are added into the water bath jacket 121 to reduce the temperature of the liquid medicine so as to increase the solubility of carbon dioxide. When necessary, compressed air is introduced through the compressed air vent pipe, so that more carbon dioxide can be dissolved in the mineral separation liquid, and scaling is accelerated. A perforated partition plate 142 is placed at the bottom of the pile-leaching container 140, filter cloth 143 is paved on the perforated partition plate 142, and gold ore raw ore 146 is piled. The dripping sprayer 130 is used for spraying the liquid medicine on the surface of the gold ore crude ore 146, and the liquid medicine gradually infiltrates. The permeate flows through the filter 141 into the permeate chamber 145. When the amount of the percolate reaches a certain amount, the centrifugal pump 202 is started, the percolate flows back to the liquid preparation container 110 through the filter 201 and the return pipe 203, and is recycled after being clarified.
