Abstract

The invention discloses a tailing processing technology. The tailing processing technology comprises the titanium concentrate screening and titanium concentrate enriching. The titanium concentrate screening comprises the following steps that S1, tailings are collected; S2, the collected tailings are graded based on the grain size to obtain a first tailing group with the large grain size and a second tailing group with the small grain size; S3, the first tailing group is introduced into a physical screening device for magnetic separation; and S4, ore with high titanium content screened in the step 3 is subjected to flotation processing to obtain titanium concentrate. The titanium concentrate enriching comprises the following steps that S5, the titanium concentrate obtained in the step 4 issubjected to hydrochloric acid processing; S6, the ore processed in the step 5 is subjected to chloridization; and S7, the ore processed in the step 6 is subjected to magnesium thermal reaction to obtain finished titanium ore. According to the tailing processing technology, the tailings after primary separation can be screened to obtain the ore with high titanium content finally. Different end products can be obtained, and practicability is high.

Description

technical field [0001] The invention relates to the field of mining industry, in particular to a tailings treatment process and a treatment system thereof. Background technique [0002] Mining industry machinery mainly includes mining machinery and mineral processing machinery, mineral processing machinery includes ore crushing, cleaning and other machinery, ore crushing methods are mainly based on the physical and mechanical properties of the ore, the size of the ore block feed and the required crushing ratio and other factors The difficulty of crushing minerals is closely related to the mechanical properties of minerals. The bonding force between different mineral geometries is smaller than the internal bonding force of the same mineral. In the same mineral aggregate, the crystal surface The bonding force is smaller than that inside the crystal, and this principle is used to separate different ores in the process of beneficiation.
