16%, V2O50.15%~0.5%.And Sichuan containing Yanbian, Baima Iron Mine reserves are up to 49.4 hundred million tons.Calculate stock number
Association vanadium V2O512610000 tons, titanium TiO24.74 hundred million tons.Due to the magnetic iron ore and titanium mineral crystal stock in v-ti magnetite ore, particle
It is coarse, and distribution of particles unevenness and difficult fine grinding.So that ore grindability coefficient is about the 1/2 of magnetite quartzite, belong to easily choosing, hardly possible
Grind the ore low with mineral purity.Cause existing other kinds of grinding machine in actual work, understands low yield, energy consumption and cost
It is higher, it is not able to satisfy actual production to the needs of low energy consumption and low cost.
And the prior art mainly uses the technique of more complex three sections mill magnetic of technique, by raw ore by it is rough and torn and in break after,
By the closed circuit screening of straight line shaker, the ore of partition size qualification enters the preceding storehouse of roll mill, it is underproof continue back at thin broken after
It is passed through the closed circuit screening circulation of straight line shaker again, the ore in the preceding storehouse of roll mill then passes through high pressure roller mill and branches to storehouse after roll mill, and
Ore after roll mill in storehouse enters one section of ball mill after throwing tail magnetic separation again multistage screening and is ground, after cyclone is concentrated
It is spare into pump pond.It pumps the ore pulp in pond and enters two sections of ball millings after a stages of magnetic separation, level-one cyclone classification, then through second level eddy flow
Device is classified, the classification of three swirler device enters the progress roughing of two stages of magnetic separation and selected, then through two sections of level-one cyclone classifications, two section two
Grade cyclone classification is selected into the progress of three stages of magnetic separation, and the TFe content in obtained final concentrate still can only achieve 55% left side
The right side causes the rate of recovery of TFe 90% hereinafter, prior art is difficult further to improve TFe's after energy consumption and cost consideration
Content.
