Embodiment Construction

[0022] The present invention will be further described below in conjunction with the drawings and specific embodiments.

[0023] Such as figure 1 , 4 As shown, -70mm titanium ore (vanadium-titanium magnetite, titanium placer) is pre-selected and washed with tailings or weathered ore, and then -10mm ore is ground and beneficiated in the magnetization roasting stage to separate the gangue minerals into ilmenite concentrate (Or titanium sand concentrate), or this ilmenite concentrate (or titanium sand concentrate) and vanadium ilmenite concentrate (or titanium concentrate) are mixed in a certain proportion and then mixed with binder (bentonite, etc.) and carbonaceous After the reducing agent is mixed, the pellets are pre-reduced or directly put into the furnace, and smelted in the electric blast furnace or submerged arc furnace to produce TiO 2 >68% of high-titanium slag (melting titanium slag) and semi-steel (alloy hot metal), the alloy hot metal is blown with vanadium and chromium...

Abstract

A process for preparing Ti-enriched material from V-Ti magnetite through preseparating to obtain Ti-Fe ore concentrate, proportionally mixing it with V-Ti-Fe core concentrate, adhesive and carbon reducer, smelting to obtain high-Ti slag and semi-steel, blowing V-Cr to melten alloy iron to obtain V-Cr contained steel slag, separating V and Cr, fire metallurge of high-Ti slag to obtain artificial rutile and microcrystal glass, ball grinding of artificial rutile and coal while adding adhesive to obtain C-contained Ti particles, calcining, cooling and classifying.

Description

Technical field [0001] The invention belongs to a method for beneficiating and smelting titanium ore (vanadium-titanium magnetite, titanium placer) metal minerals, in particular to manufacturing iron and steel products from rock-type vanadium-titanium magnetite surface ore, surface ore and weathered ore, and extracting sulfuric acid The high-grade acid-soluble titanium-rich material used in the titanium dioxide plant and the carbon-containing rutile titanium-rich material and vanadium-chromium products used in the chloride-process titanium dioxide plant and the comprehensive utilization of other valuable elements. Background technique [0002] In nature, titanium resources usually form solid solutions with other metal oxides, especially iron oxides (rutile), or independent minerals (vanadium-titanium magnetite, titanium placer, etc.) in an oxide state. The titanium ore referred to in the present invention refers to titanium ore deposits (primary vanadium-tita...
