AI Technical Summary

Technical Problem

Existing mechanical filtration processes are prone to clogging of filtration channels due to the densification of silica gel when processing vanadium-containing ores and solid waste, leading to difficulties in deep dehydration and extraction, especially in high-viscosity, high-silica systems.

Method used

By applying a high-frequency alternating magnetic field and a low-frequency pulsed ultrasonic field to the suspended slurry, magnetothermal stress and acoustic flow micro-vortex flow are induced, forming microcrack channels and establishing a chain-like support skeleton. Combined with a steady-state magnetic field and an asymmetric alternating electric field, magnetomechanical reconstruction and electroosmosis drive are achieved, overcoming the correlation between mechanical negative pressure and gel densification, and ensuring unobstructed permeation channels.

Benefits of technology

The effective decoupling of mechanical negative pressure and gel densification improves solid-liquid separation efficiency, avoids high temperature and high pressure conditions, and achieves efficient extraction of vanadium components under normal pressure.

Abstract

The present application relates to the technical field of ore processing, and discloses a soaking and suction filtration extraction process for synergistically treating vanadium-containing ore and solid waste, which comprises the following steps: crushing and mixing vanadium-containing ore and vanadium-containing solid waste according to a set mass ratio, adding a leaching solvent to configure a suspension slurry, inducing thermal stress of a magnetic phase by applying a high-frequency alternating magnetic field, and generating micro-crack pores at the grain boundaries; introducing the suspension slurry into a soaking reaction kettle, exciting an acoustic flow micro-vortex flow by applying a low-frequency pulse ultrasonic field, and stripping the solid-phase reaction products on the inner wall of the micro-crack; after the soaking reaction is completed, introducing the suspension slurry into a suction filtration device, inducing in-situ reconstruction of the incompletely consumed magnetic residues into a chain-shaped support skeleton to bear mechanical compressive stress by applying a steady-state directional magnetic field, generating an electrophoretic repulsive force to prevent interface adhesion and blind of free silica acid gel by applying an asymmetric alternating pulse electric field, and generating an electroosmotic driving force to accelerate the filtration of the vanadium ion-rich liquid phase. The process breaks through the technical bottleneck of the difficulty in deep dehydration of a high-viscosity high-silicon system.
