Embodiment 1

[0062] The invention provides a method for separating diamond mixture, as attached figure 1 shown, including the following steps:

[0063] 1) The mixed material containing iron-cobalt-nickel catalyst, graphite and diamond is sheared and compounded by a squeeze crusher with a shearing function to obtain a material with a particle size of less than 3.0mm; then it is ground by a milling machine, A dissociated and finer-grained ground mixture was obtained with a material content of 70% of particle size -0.074 mm. Among them, the small bat medium, the large wood medium, and the water medium are added to the mill; the ratio of the small bat medium to the large wood medium is 1:2.

[0064] 2) Pass the pulverized mixed material through a hydrodynamic ultrasonic dispersing device for 9 cycles of ultrasonic dispersion treatment to obtain a fully dispersed ultrasonic dispersion mixture.

[0065] 3) The ultrasonic dispersion mixture is first subjected to magnetic separation by a weak ma...

Abstract

The invention relates to a method for separating a diamond mixture. The method comprises the following steps that (1) mixed raw materials containing diamond, graphite and an iron-cobalt-nickel catalyst are smashed to obtain a smashed mixture; (2) the smashed mixture is subjected to ultrasonic wave dispersed processing to obtain an ultrasonic wave dispersed mixture; (3) the ultrasonic wave dispersed mixture is subjected to magnetic separation, an iron-cobalt-nickel catalyst product is removed, and a diamond and graphite mixture is obtained; (4) the diamond and graphite mixture is subjected to ultrasonic wave dispersed processing to obtain a dispersed diamond and graphite mixture; and (5) the dispersed diamond and graphite mixture is subjected to staged separation, so that diamond and graphite are separated. Compared with a traditional diamond mixture separating method, the method for separating the diamond mixture is clean and environment-friendly, no chemical reagent is used in the separating process, environmental pollution cannot be caused, and discharge of the three wastes is avoided. The diamond, the graphite and the iron-cobalt-nickel catalyst are respectively separated, so that the purity is high; the graphite and the catalyst matter can be recycled to be reused; and the diamond extraction efficiency is high, and the economic returns are good.

Description

technical field [0001] The invention belongs to the field of separation and purification of diamond mixtures, and in particular relates to a method for separating diamond mixtures. The diamond mixture is dispersed into fine particles, and then diamond, graphite, and iron-cobalt-nickel catalyst products are phase-separated. Background technique [0002] Diamond, commonly known as "diamond", is an allotrope of carbon, and it is the hardest substance naturally occurring in nature. Graphite is also a crystalline mineral of carbonaceous elements, and its crystalline framework is a hexagonal layered structure. Both diamond and graphite are minerals composed of carbon, and the physical and chemical properties of elemental carbon depend on its crystal structure. High-hardness diamond and soft and smooth graphite have different crystal structures, and their appearance, density, melting point, and use are all different. Diamonds are used in a wide range of applications, such as: geo...
