Problems solved by technology

The dielectric sorting methods used in the industry all have electrodes in direct contact with the medium. Due to the high-voltage discharge of the electrodes, impurity gases are generated from the electrolytic medium, etc., which have brought many safety hazards to the sorting system and increased the post-processing process.
At the same time, the structure of strong gradient electric separation is complex in industry, and the cost of maintaining high-voltage electric field is relatively high.
In summary, the mineral electroseparation method faces problems such as low separation efficiency, impurities generated by the electrolytic medium, complex structure, and high cost.

Abstract

The invention discloses an insulating dielectrophoresis ore separation system which comprises a preprocessing storage unit, a first pump and an ore separation unit. The ore separation unit comprises an ore powder suspension liquid inlet I formed to input ore powder suspension liquid conveyed through the first pump, an electrolytic solution inlet II formed to input an electrolytic solution, a mainrunner, a current-conducting plate I and a current-conducting plate II, wherein the current-conducting plate I and the current-conducting plate II are arranged oppositely. The main runner is arrangedto converge the ore powder suspension liquid from the ore powder suspension liquid inlet I and the electrolyte solution from the electrolyte solution inlet II so that mixed liquor can be formed. The current-conducting plate I and the current-conducting plate II located on the main runner are connected with an electrode I and an electrode II correspondingly. A strong gradient electric field is formed between the current-conducting plate I and the current-conducting plate II. The electrode I and the electrode II are connected with a positive pole and a negative pole of a power source correspondingly. The mixed liquid is separated through the strong gradient electric field, thus ore powder suspension liquid selected fine is output through a fine selecting guide body ore powder suspension liquid outlet I and fine selecting non-guide body ore powder suspension liquid outlet III, and residual suspension liquid is output through a residual suspension liquid outlet II.

Description

technical field [0001] The invention relates to the technical field of ore separation, in particular to an insulating dielectrophoresis ore separation system. Background technique [0002] Naturally mined ores are large in size and have too many impurities to meet the requirements of industrial processing and manufacturing. Therefore, a series of continuous processing is required for the mined ores, which is called beneficiation. The processing of ore dressing is divided into preparatory work before sorting, sorting operation, and dehydration after sorting. Sorting methods include gravity separation, flotation, magnetic separation, electric separation and so on. Among them, gravity separation (gravity separation), magnetic separation and flotation are currently the most commonly used separation methods. However, these three separation methods have their defects, such as the low content of useful minerals in finished products after gravity separation and flotation. The sepa...
