Title:
RED MUD COMPREHENSIVE UTILIZATION METHOD AND DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/095263
Kind Code:
A1
Abstract:
A red mud comprehensive utilization method and device. The red mud comprehensive utilization device comprises a red mud pretreatment device (2), a red mud drying bin (3), a feeding device (4), an atmospheric micro-plasma discharge device (5), a red mud treatment cavity (6), a gas recovery device (9), a discharging device (7), a waste heat recovery device (11), a grinding and screening device (8), a treated red mud bin (10), and a control device (1). The red mud comprehensive utilization method comprises: pretreating red mud, and performing evaporation to remove moisture and then grinding; feeding the red mud into the red mud treatment cavity (6); and starting the atmospheric micro-plasma discharge device (5), inputting electromagnetic energy into the red mud treatment cavity (6) via a multi-phase electrode (17) by means of a discharge power source (16), enabling the treated red mud to enter an ore dressing device from the treated red mud bin, and respectively separating out iron and titanium from the red mud, and using the remaining part as a refractory material raw material. The impact excitation bombardment effect of electrons and active particles generated by atmospheric micro-plasma discharge is utilized, and a composite oxide is dissociated into a relatively simple oxide which is easy to separate, thereby providing convenience for subsequent ore dressing; the method is rapid and efficient.
