The method and process of titanium-zirconium ore processing depend on the type of deposit, the nature of ore and the composition of mineral deposits. Considering that the primary titanium ore (vein ore) is near to the ore property, the intended mineral variety is relatively simple, and the selection method and technological process are common. And titanium placer and zirconium ore deposits in titanium, zirconium mineral deposits and monazite, phosphor yttrium ore, cassiterite and precious metals, such as symbiosis, shows the induction of placer production, so, titanium, zirconium placer ore dressing from coarse to select more sodium into the ore processing process. Based on this in this section of titanium, zirconium ore dressing is divided into titanium primary ore (vein ore) main ore and titanium, zirconium dressing dressing two parts.
Titanium primary ore (vein ore) dressing
Currently, the primary titanium ore (vein ore) used in industry is composite iron ore containing titanium. In order to utilize the titanium resources, the whole process can be divided into three stages: preseparation, iron separation and titanium separation. During the selection of titanium parts can be divided into two stages of rough selection and selection.
(1) pre-selection
In some titanium vein ore ores, under the condition of crushing to a certain degree of coarse grain, there is an appropriate amount of gangue to reach the ultimate monomer dissociation, and these coarse monomer gangue can be discarded by pre-selection operation to reach the intention of adding processing ability and improving grade. Preseparation can be carried out according to the properties of ore in the suitable stages of coarse, medium and fine crushing before grinding. Magnetic separation and re - separation are two common ways of pre - separation.
(2) iron selection
The primary purpose of the present industrial use of iron-bearing compound iron ore is to obtain iron concentrate for iron-making; For ore with high vanadium content, iron vanadium concentrates are obtained for iron smelting and vanadium extraction. Iron selection using a simple useful magnetic separation method. After the selected ore is crushed (or pre-sorted) and ground to reach the separation degree of optional monomer, iron concentrate or vanadium iron concentrate is selected by drum type, belt type weak magnetic field temperature magnetic separation machine, magnetic separation tailings are the material of titanium recovery.
Some ore iron, titanium mineral deposits are inlaid with fine, select a single method of ore dressing is difficult to get a single concentrate, then only by reelection to lose tailings, the obtained iron, titanium mixed concentrate, direct melting and smelting, to produce high purity pig iron and iron slag products.
(iii) titanium selection
The recovery of titanium in the titanium vein ore is carried out in the magnetic separation tailings after iron concentrate is selected. Titanium can be separated by gravity separation, magnetic separation, electric separation and flotation. Depending on the properties of ores, suitable separation methods are selected to form different technological processes for separation.
