A kind of metallurgical slag recovery method

Abstract

The invention relates to a dielectric field screening concentrating machine and a metallurgical slag recovering method. The dielectric field screening concentrating machine comprises a supporting frame, a sorting box, an ore feeding part, a dielectric sieve screen, multiple electrode plates, a quick-return mechanism, a tailing outlet and a concentrate outlet. The tail portion of the dielectric sieve screen is provided with a rotary scraping plate connected to the concentrate outlet. The tailing outlet is located in the lower portion of the sorting box. The multiple electrode plates are installed on the dielectric sieve screen and the ore feeding part in parallel. An insulating layer is attached to the outside of each electrode plate. According to the machine, the heat-preserving no-heating method is adopted for enabling ore to be fully crystallized and grow up, additional energy is not needed, according to the crystallization differentiation principle, the efficiency ratio of crystallization and growth of enrichment phases of metallic oxide is maximized, the dielectric chaining and screening method is adopted for separating ultrafine ore, the process is the physical process, then the dielectric liquid physical method is adopted for carrying out recovering to ensure zero emission of pollutants in the whole process, and useful metallic oxide in the metallurgical slag can be utilized efficiently and environmentally friendly.

Description

technical field [0001] The invention relates to the technical field of separation of metallurgical dielectric minerals, in particular to a method for recovering metallurgical slag. Background technique [0002] At present, in the associated polymetallic deposits, there are often some associated elements after smelting and recovery of certain metals, such as titanium in the smelting process of vanadium-titanium magnetite cannot be recovered, these useful metals and impurity elements are in the process of slow cooling and crystallization Often enter different mineral phases, useful metals are generally in metal oxide mineral phases, and the main impurity silicon often forms silicate minerals together with lithophile elements. The biggest difference in properties between these silicate minerals and useful metal oxides is The dielectric properties are different. The dielectric constant of useful metal oxides is usually large, and the dielectric constant of silicate minerals is u...
