Description
Technical field
The present invention relates to Talc Ore technical field of beneficiation, the method for specifically a kind of low-grade Talc Ore purification.
Background technique
The talcum ore resources in China are more abundant, have reserves in each area in the whole nation, but high-quality Talc Ore is at present
It is produced totally, and low-grade Talc Ore is not directly applicable in industrial production, it is necessary to it is processed just by certain ore dressing
It is preferably national economy service that talcum ore resources, which can be allowed,.Since the low-grade Talc Ore accompanying impurities mineral type in China is more
, associated structure is complex, therefore the ore dressing processing of Talc Ore is particularly important.
Currently, the Talc Ore ore-dressing technique and equipment in China more fall behind, the ore dressing of external Talc Ore is mainly introduced
Purifying technique and equipment.Main purification by mineral method has: flotation, picking, electrostatic separation, magnetic separation, photoelectricity pick,
Selective crushing and screening (high-quality Talc Ore) etc..External talcum purification by mineral technology development is very fast, uses photoelectricity already
The gangue mineral that color is deeper in Talc Ore is rejected in choosing instead of picking；Foreign countries' floatation, magnetic separation and electrostatic separation pick
It is widely applied except the associated mineral technique in talcum out has been obtained.But majority is single ore-dressing technique, obtains talcum
Purity is not high, and with the talcum for obtaining higher degree, single ore-dressing technique is extremely difficult to.
Summary of the invention
The purpose of the present invention is to provide a kind of methods of low-grade Talc Ore purification, to solve to deposit in above-mentioned background technique
The problem of.
The technical scheme of the present invention is realized as follows:
A kind of method of low-grade Talc Ore purification, comprising the following steps:

(3) ore on step (2) sieve is sent to impact crusher and is crushed again, obtain ore fine crushing；
(4) step (2) are sieved into lower ore and step (3) ore fine crushing send to rectangular vibrating screen and sieves, ore is pre- on sieve
Tailing is thrown, lower ore is sieved and send to ceramic ball mill progress ore grinding；
(5) step (4) ore grinding ore discharge is sent to magnetic separator and is sorted, obtained magnetic concentrate and magnetic tailing, magnetic concentrate are
For the iron-bearing mineral removed out；
(6) step (5) magnetic tailing is sent to flotation column coarse classifier and carries out roughing, obtain rougher concentration and rougher tailings；
(7) by step (6) rougher concentration send to flotation column refiner carry out it is selected, obtain selected concentrate and cleaner tailings, will be smart
Concentrate selection obtains final talcum concentrate product by filter dehydration, and filter overflow returns to recycling water utilization system and carries out return water benefit
With rougher tailings and cleaner tailings are flotation tailing.
Preferably, the screen size of step (2) the oblong rectangular shape sieve is 5 ~ 8mm.
Preferably, the screen size of the rectangular vibrating screen of the step (4) is 3 ~ 5mm.
Preferably, the ore grinding time of step (4) ceramic ball mill is 3 ~ 5min.
Preferably, the magnetic field strength of step (5) magnetic separator is 10000 ~ 12000Qe.
Preferably, the pulp density of step (6) the flotation column coarse classifier is 18 ~ 20%, and the collecting agent of roughing addition is ten
Eight amine, dosage are 400 ~ 450g/t ore pulp, and foaming agent is methyl ether alcohol, and dosage is 20 ~ 30g/t ore pulp.
Preferably, the pulp density of step (7) the flotation column refiner is 15 ~ 18%, and the collecting agent of selected addition is ten
Diamines, dosage are 300 ~ 350g/t ore pulp, and foaming agent is methyl ether alcohol, and dosage is 15 ~ 20g/t ore pulp.
The invention has the benefit that
The present invention uses preparatory stage crushing-screening-magnetic separation-two-stage flotation technique, using preparatory stage crushing-sieving technology,
Broken by two sections, different shape sieve pore screening, selective preparatory throwing removes a part of tailing, improves into the pure of wear smooth stone ore
Degree, while reducing into mill amount, energy consumption is reduced, again by magnetic separation and two-stage flotation technique, the impurity such as iron, quartz are removed, into one
Step improves talcum purity, and two-stage flotation is respectively adopted different collecting agents, both ensure that the talcum rate of recovery, also ensures that talcum is pure
Degree, the talcum purity is high of acquisition, whiteness are high.
