Abstract

The invention provides a vanadium titano-magnetite grinding aiding method and system. The method comprises the following steps: preparing a citric acid solution with a certain concentration; carryingout primary crushing on the vanadium titano-magnetite; screening the crushed vanadium titano-magnetite through a fine screen, crushing the vanadium titano-magnetite left on the fine screen again, andenabling the vanadium titano-magnetite passing through the fine screen to serve as crushed ore; feeding the crushed ore into a mill, and adding a citric acid solution for ore grinding; and carrying out water screening on the vanadium titano-magnetite obtained after ore grinding through a standard screen. According to the method, the prepared citric acid solution is added in the ore grinding process to assist in grinding, so that the surface activity of minerals is changed, the ore grinding efficiency is effectively improved, the ore grinding energy consumption is reduced, and the ore dressingcost of the vanadium titano-magnetite is reduced.

Description

technical field [0001] The invention relates to the technical field of mineral processing, in particular to a vanadium-titanium-magnetite grinding aid method and system. Background technique [0002] As an important source of iron, vanadium-titanium magnetite is accompanied by various components such as vanadium, titanium, cobalt, and chromium, and has high comprehensive utilization value. When using vanadium-titanium magnetite, especially in the beneficiation process of vanadium-titanium-magnetite, the energy consumption of the grinding process accounts for more than 70% of the total energy consumption of vanadium-titanium-magnetite beneficiation, and the power consumption is large. high cost. Therefore, there is an urgent need for a grinding method to improve grinding efficiency, reduce grinding energy consumption, and save production costs. Contents of the invention [0003] In view of this, the object of the present invention is to provide a vanadium-titanium-magneti...
