Description
The product represented by this dataset is titanium slag, a titanium-rich industrial slag product obtained from titanium concentrate after smelting enrichment to extract titanium and remove impurities. In titanium slag, the titanium dioxide content is significantly increased and impurities such as iron are effectively removed, giving it a high TiO₂ grade and good chemical stability. Its physical properties include a relatively high melting point, high hardness, and brittleness, and it generally appears as grey-black or brownish-black lumps. The upstream feedstock of this product is titanium concentrate, and downstream it is a core raw material for the further preparation of titanium tetrachloride and titanium sponge, and can also be applied in the preparation of titanium-based pigments and metallurgical auxiliary materials. It is an important intermediate product that links upstream and downstream in the titanium metallurgy industry chain. The dataset includes the main raw and auxiliary materials, energy, and waste in the production process; infrastructure such as the manufacturing of production equipment and the construction of plants is not included within the dataset boundary. The data inventory is formed by merging data from multiple sources.
Activity Description
In the electric-furnace smelting process, titanium concentrate is uniformly mixed with a specified proportion of semi-coke (residual coke) and fed directly into a titanium-slag electric arc furnace. During reduction smelting, iron oxide is reduced to metallic iron, thereby concentrating titanium dioxide in the titanium slag. The system covers the full process from titanium concentrate to titanium slag.
Process Description
The titanium dioxide content in titanium slag is significantly increased, and impurities such as iron are effectively removed, so it has higher TiO2 grade and better chemical stability. It has a high melting point, high hardness, and is brittle. It is generally a gray-black or dark-brown block. Due to its relatively stable composition and low impurity content, titanium slag is an important raw material for the further preparation of titanium tetrachloride and titanium sponge. It also has certain application value in the fields of pigments, metallurgy and other fields.

Technology comment
The production process of electric furnace smelting is as follows: mix titanium concentrate with a certain proportion of blue coke (residual coke) evenly, add it directly into the titanium slag electric arc furnace, reduce iron oxide to metallic iron through reduction smelting, and enrich titanium dioxide to obtain titanium slag.
