Technology of titanium slag production in an ore-thermal furnace using a single-stage method

JSC “Titanium Institute” has a modern advanced technology for producing titanium slags in an ore-thermal furnace using a single-stage method.

We offer ready-to-implement technological solutions for producing titanium slags in an ore-thermal furnace with 25 MVA transformers.

Design of a full complex of the technological process for producing titanium slags in arc ore-thermal furnaces (ARF).

Titanium slag is a product in high demand on the world market.

The process of producing titanium slags from ilmenite concentrates involves smelting ilmenite concentrate in arc ore-thermal furnaces (ARF). Smelting occurs in a semi-closed mode on a powder charge with the production of titanium slag with a given content of iron oxide, as well as associated metal (cast iron).

The technology for obtaining titanium slags allows them to be produced as a commercial product both for obtaining titanium sponge and for producing titanium dioxide pigment using chlorine or sulfate methods.

APPLICATION

– 95% of the total production volume is used to obtain pigment titanium dioxide for use in the following industries:

• Production of white pigment for the pulp and paper industry
• Paint and varnish industry
• Production of synthetic fibers
• Nanotechnology
• Production of plastics
• Production of heat-resistant and optical glass
• Production of white ceramics
• Production of ceramic dielectrics
• Production of rubber products

– 5% of the total volume is the production of metallic titanium (titanium sponge) for use in the following industries:

• Aircraft engineering
• Rocket engineering
• Shipbuilding
• Chemical industry
• Cryogenic engineering
• Electroplating
• Oil and gas industry
• Food industry
• Medicine
• Sports equipment
• Jewelry production

ADVANTAGES OF THE TECHNOLOGY AND GUARANTEED PERFORMANCE

• Guaranteed performance indicators of the proposed technology for the production of titanium slag in ore-thermal furnaces (RTF):
• RTF productivity – 62,627 tons/year;
• titanium extraction from concentrate (with return of recycled dust) into marketable products (titanium slag) – at least 98%;
• obtaining titanium slag of a given composition – TiO₂ content – 84-90% and FeO – 5-7%;
• obtaining titanium slags in the form of marketable products both for the production of sponge titanium and for the production of pigment titanium dioxide by chloride or sulfuric acid methods;
• obtaining by-product high-quality metal;
• all processes of material transportation, loading and unloading, grinding, classification, dosing and mixing, briquetting, drying, are mechanized and automated;
• ensuring explosion safety of the process and utilization of secondary energy resources.

PROJECTS

Over 10 completed projects for the full complex of titanium slag production in RTP in various countries of the world, including those commissioned by Panzhihua Iron & Steel (Group) Company, PRC, UKTMK JSC, Republic of Kazakhstan, Saraf Agencies Pvt. Ltd., Republic of India, TRAFALGAR, Republic of India, SMELSAPL, Republic of India, IRENA GROUP INVESTOR SP ZOO, Poland.

In the process of design work, JSC “Titanium Institute”, if necessary, can develop a 3D model with the mandatory use of BIM technologies (Revit).
