Embodiment 1

[0028]The extract components of plant A are the extract components after the combination of seaweed, kelp, mustard, angelica, cloves, and mint in a weight ratio of 1:1:1:1:1:1;

[0029] The extract component of plant B is the extract component after mixing false physalis, clover, and sorrel according to the weight ratio of 1:1:1;

[0030] Preparation of plant A extract components: seaweed, kelp, fenugreek, angelica, cloves, and mint are mixed in a weight ratio of 1:1:1:1:1:1 and then pulverized, and a certain amount of distilled water is added to make the material-to-liquid ratio 1:30 , stirred and soaked at 80°C for 11h, and then carried out ultrasonic extraction, the ultrasonic extraction power was 1150w, and the extraction time was 23min, and then the filter residue and filtrate were separated by filtration, and the filter residue was repeatedly extracted for 3 times. Filtrate, the total filtrate is concentrated so that the concentrated solution volume is 1 / 5 of the origina...

Abstract

The invention belongs to the technical field of rare-earth ore processing, and specifically discloses a recycling method for ion type rare-earth ore smelting and separating magnesium salt wastewater.The recycling method comprises the following steps of: (1) preparing a plant A extracted component: getting, mixing and crushing laver, kelp and dried sea grass, adding distilled water to soak for 10-12 hours, performing ultrasonic extraction, filtering, separating and filtering; (2) preparing a plant B extracted component: mixing and crushing false physalis, clover and creeping oxalis, adding distilled water to stir and soak for 10-12 hours at certain temperature, performing ultrasonic extraction, filtering, separating and concentrating; (3) adding the plant A extracted component into magnesium salt wastewater, stirring at the normal temperature, adding lime milk to react after regulating the temperature, and leading in CO2 gas to react to obtain a magnesium bicarbonate solution; and (4)adding vegetable gelatin into the magnesium bicarbonate solution, standing after adding microorganisms, and extracting and separating to obtain a rare-earth product and treated magnesium salt wastewater after adding the plant B extracted component and naphthenic acid.

Description

technical field [0001] The invention belongs to the technical field of rare earth ore processing, in particular to a method for recycling and utilizing waste water of ionic rare earth ore smelting and separating magnesium salts. Background technique [0002] Ionic rare earth ore, also known as weathering crust leaching rare earth ore, is adsorbed on minerals in the form of ions, and adsorbed on the surface of clay minerals in the form of hydrated or hydroxyhydrated cations, and can be dissociated by chemical and biological actions. . Ionic rare earth ore is rich in medium and heavy rare earth elements, and has the characteristics of complete distribution, abundant resource reserves, high grade and low radioactivity. Because of its rich and unique physical and chemical properties such as light, magnetism and electricity, ionic rare earth ore has good compatibility with other materials, can form new materials with different properties and a wide variety, and can greatly impro...
