Description
Technical field
The invention belongs to technical field of beneficiation, more particularly to a kind of two product ore-dressing technique of apatite ilmenite.
Background technique
Titanium has the advantages of steel (intensity high) and aluminium (quality is light) concurrently simultaneously, pure titanium has good plasticity, it tough
Property more than 2 times of pure iron, heat-resisting and corrosion resistance is also fine.Since titanium there are these advantages, rare gold outstanding is promoted it as
Category, titanium and its alloy are first utilized in manufacture aircraft, rocket, guided missile, naval vessels etc., are widely used in chemical industry and petroleum again later
Department.
Ilmenite is main titaniferous ore, is the most important source of Titanium, TiO2Theoretical content 52.66%, iron
Content be generally between 20%-30%.The chemical component of ilmenite is related with formation condition.Currently, many mines are contained greatly
Apatite-ilmenite of amount.The ore in similar area mine generally contains TiO2Content is between 4%-8%, TiO2Content is higher,
The condition for having the ilmenite concentrate for obtaining high-quality.Its P2O5Content be generally 2% or more, P2O5Mainly in the form of apatite
In the presence of；Furthermore this kind of ore often ilmenite also with a certain amount of magnetic iron ore association, and also contain a small amount of martite, this
A little iron minerals are similar with the specific gravity of ilmenite and also similar to the affinity of water, so it easily in the gravity treatment of ilmenite and is floated
It chooses and is entered in ilmenite concentrate with ilmenite, cause ilmenite concentrate grade not high.Also containing a certain amount of in the gangue of this ore
It containing magnesium mica, if these magnesium are not deviate from, enters eventually into ilmenite concentrate, the credit rating of ilmenite concentrate can be reduced, reduce
Its price.Furthermore this kind of mineral phosphorus content is higher, if can recycle to phosphorus, not only conforms with the principle of resource high-efficiency recycling,
And the economic benefit for selecting factory will be further increased in the phosphorus concentrate obtained.
From the above, it is seen that green ore TiO2It is higher, P2O5Content it is also higher, content of MgO is also higher, and
Contain a certain amount of iron mineral, also to obtain good titanium fine powder, it is necessary to in ore iron and magnesium deviate from, to obtain
Synthetical recovery must also be subject to phosphorus by obtaining higher economic benefit.So we can effectively improve titanium essence it is necessary to develop one kind
TiO in powder2Content, apatite-ilmenite that iron content and content of MgO is effectively reduced select phosphorus to select titanium deferrization de-magging technique.

Mine effectively realizes the separation of titanium and phosphorus, is that subsequent titanium flotation and phosphorus flotation obtain qualified ilmenite concentrate and phosphorus concentrate and create
Advantageous condition, titanium phosphorus separating flotation, which also helps, further reduces equipment investment and energy consumption.Titanium phosphorus is separated later floating
Concentrate after choosing carries out the sub- process of titanium ore dressing, and obtaining yield is 10.96%, TiO2Content is 45.0%, P2O5Content
Content for 0.05%, Fe is 22.6%, the content of MgO is 0.45%, TiO2The rate of recovery be 58.0%, P2O5The rate of recovery
For the 0.24%, ilmenite concentrate that the Fe rate of recovery is 18.34 and the MgO rate of recovery is 1.41%.TiO2Grade and the rate of recovery it is all fine,
Content of magnesia is low, P2O5Content is low, and the index of ilmenite concentrate is very good, is high-quality ilmenite concentrate.To the tailing after titanium phosphorus separating flotation
Using the technique of phosphorus flotation, obtaining yield is 3.51%, TiO2Content is 0.7%, P2O5Content be that 38.0%, Fe contains
Amount is 1.3%, the content of MgO is 0.4%, TiO2The rate of recovery be 0.29%, P2O5The rate of recovery be 58%, the Fe rate of recovery is
The phosphorus concentrate that the 0.34% and MgO rate of recovery is 0.4%.P2O5Grade and the rate of recovery it is all fine, impurity content is lower, this part
The acquisition of phosphorus concentrate not only increases the comprehensive utilization ratio of resource, but also increases the economic benefit for selecting factory.
