Problems solved by technology

Its main process flow is: raw ore→one stage ball mill→cyclone classification→one stage coarse magnetic separation→second stage ball mill→second stage cyclone classification→high frequency fine sieve classification→second stage fine magnetic separation→selection→sweeping→ Filtration and dehydration → concentrate, but the amount of grit or sieve products returned by this process is relatively large, and the raw ore table is low, which is difficult to meet the gradually expanding production needs

Embodiment Construction

[0013] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. It should be noted that, in this specification, the percentages involved refer to percentages by weight, which will not be described in detail below.

[0014] figure 1 It is the flow chart of the original beneficiation process of vanadium-titanium magnetite. figure 2 It is a flow chart of the beneficiation process of the vanadium-titanium magnetite of the present invention.

[0015] Such as figure 1 As shown, the original beneficiation process is to send the raw ore to the first-stage cyclone for classification after being crushed by the first-stage grinding, and return the grit to the first-stage grinding to combine with the new ore for regrinding. One-stage grinding, two-stage cyclone classification, high-frequency fine sieve, two-stage magnetic separation, beneficiation, sweeping, and filtration to obtain vanadium-titanium magnetite concentrate. However,...

Abstract

The invention discloses a mineral separation method for vanadium-titanium magnetite ores. The mineral separation method comprises the following steps of: conveying raw vanadium-titanium magnetite ores to a primary grinding stage; conveying the crushed vanadium-titanium magnetite ores to a primary swirler for classification; conveying deposited sand of the primary swirler to a magnetic separator for magnetic separation, demagnetizing primary tail-ground refined ores subjected to magnetic separation, and returning to the primary grinding stage for grinding again, wherein the tail-ground tailings subjected to magnetic separation are final tailings; and sequentially performing primary rough magnetic separation, secondary grinding, secondary swirler classification, high-frequency fine screening classification, secondary magnetic separation, fine separation, sweeping, filtration and dehydration on overflowed ores of the primary swirler so as to obtain the vanadium-titanium magnetite ores and the final tailings. Compared with the prior art, the treatment capacity and the yield of a vanadium-titanium magnetite ore mineral separation system are improved, the raw ore machine time and the fine ore machine time are prolonged, and great economic benefit can be obtained.

Description

technical field [0001] The invention relates to an ore dressing method, in particular to a new method for ore dressing of vanadium-titanium magnetite. Background technique [0002] my country's vanadium-titanium magnetite deposits are widely distributed and rich in reserves, and the storage and mining volume ranks third in the country's iron ore. The vanadium-titanium magnetite in Panzhihua has the characteristics of large remanence and strong coercive force, and it is difficult to grind and classify; and the magnetite and titanium minerals are crystal-linked, and they exist in the same quality as vanadium. It also increases the difficulty of grinding. In recent years, with the improvement of mining capacity, low-grade off-surface ore accounts for an increasing proportion of the total ore reserves. When dealing with ore with large mud content, a large amount of mud-containing waste will be thrown into the tailings, affecting Productivity and recovery. [0003] At present,...
