Description

Technical Field

[0001] The utility model belongs to the technical field of smelting equipment, and in particular relates to a closed alkali leaching reaction device for antimony-containing gold concentrate. Background Art

[0002] Antimony-containing gold concentrate usually uses alkaline leaching and antimony electrolysis to separate gold and antimony, and recover antimony; then the gold, silver and other valuable metals are recovered by pyrometallurgy or hydrometallurgy. When alkaline leaching is performed on antimony-containing gold concentrate, auxiliary materials such as sodium sulfide and sodium hydroxide need to be added, and the leaching temperature is 60 ℃~80 ℃. In the prior art, a traditional open leaching device is used. Under the strong alkaline environment, polysulfides and oxygen in the air, gold will be leached together with antimony and enter the antimony-containing rich liquid, causing difficulties in gold recovery and reduced quality of raw antimony, which seriously affects the economic value of antimony and gold smelting. At the same time, temperature control is difficult, energy is wasted, and many heating sources are required. Therefore, it is necessary to design a new alkaline leaching reaction device for antimony-containing gold concentrate to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0011] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0012] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0013] See attached Figure 1-2 A closed alkaline leaching reaction device for antimony-containing gold concentrate includes a shell 13, on the top of which are arranged a feeding port 1, two reserved ports 2, 12, a water replenishment port 3, a flue gas condenser outlet 4, a discharge port 11, an auxiliary material inlet 5, an air inlet 8, a thermometer port 6, and a sight glass port 7. The sight glass port 7 is a polyethylene transparent window, and a cleaning vane 18 is arranged in the window to facilitate observation of the reaction situation in the reactor. The shell 13 is a sealed setting, and a motor 14 is arranged on the top of the shell 13, and the motor 14 is connected to a stirring shaft 16 located in the shell 13. A heating circulation steam pipe 17 is arranged on the inner wall of the shell 13, and a steam inlet 9 and a steam outlet 10 are arranged in the middle of the shell 13, and the steam inlet 9 and the steam outlet 10 are connected to the heating circulation steam pipe 17.

[0014] Antimony-gold concentrate is added into the reactor through the feeding port, and auxiliary materials are added into the reactor through the auxiliary material inlet. According to the calculated liquid-solid ratio, a certain amount of water is added through the water replenishment port. The steam valve is opened to indirectly control the temperature in the reactor by controlling the steam flow rate. At the same time, the air inlet is opened to replace the air in the reactor with nitrogen to ensure that the reactor is in an inert gas atmosphere during the reaction. When the temperature rises to the specified reaction temperature, the nitrogen is stopped, the corresponding valve is closed, and the stirring button is turned on. After the reaction for 1 hour, the reaction situation in the reactor is observed through the sight glass. If the reaction is completed, the steam and stirring are stopped, and the mixed slurry after the reaction is pumped to the next process through the discharge port.

[0015] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
