Description

Technical Field

[0001] The utility model relates to the technical field of gold ore recovery, in particular to a ore dressing device capable of improving the gold ore recovery rate. Background Art

[0002] Ore dressing is the process of selecting useful minerals from the collected mineral raw materials based on the differences in the physical properties, physicochemical properties and chemical properties of various minerals. The device that implements this process is called an ore dressing device. When the existing ore dressing device is performing ore dressing, it is easy for fragments and dust to accumulate on the surface of the screen, causing the mesh of the screen to be blocked, slowing down the impurity screening speed and reducing the ore dressing efficiency.

[0003] For example, Chinese patent announcement No. CN220004827U discloses a mineral processing device for improving the gold recovery rate of gold mines. When in use, ore is input into the mineral processing box through the opening on the top surface of the mineral processing box, and the top cover is closed. The transmission shaft is driven by a motor to rotate, so that the grinding tooth cutter rotates for grinding, and the hydraulic rod can drive the motor to move repeatedly in the mineral processing box to make the grinding more uniform. When screening, the mineral processing box can be vibrated by the vibration motor on the connecting frame, so that the screen can vibrate to prevent the accumulation of fragments and dust from affecting the impurity screening speed. At the same time, due to the setting of the telescopic rod and the spring, the vibration effect is better.

[0004] However, the mineral processing device for improving the gold recovery rate of gold ore in the above application only grinds and crushes the ore, and the gold ore powder is mixed, but no corresponding screening mechanism is set, and subsequent screening treatment is required. Therefore, there are certain limitations.

[0005] For this reason, we urgently need to provide a mineral processing device that can improve the gold ore recovery rate. Utility Model Content

[0006] The purpose of the utility model is to provide a mineral processing device capable of improving the recovery rate of gold ore, so as to solve the problem that the mineral processing device for improving the gold recovery rate of gold ore proposed in the above-mentioned background technology only grinds and crushes the ore, the gold ore powder is mixed, and no corresponding screening mechanism is set, and subsequent screening treatment is required.
