Description
The product represented by this dataset is titanium concentrate, a high-grade titanium-bearing mineral product enriched from titanium ore through a beneficiation and purification process, in which the titanium dioxide (TiO₂) content is 41.82%, corresponding to a titanium (Ti) grade of 25.1%, with titanium dioxide as its main component. Titanium concentrate generally appears as black or dark-grey powder or granules with a certain metallic luster. It has a high specific gravity, is chemically stable, high-temperature resistant, corrosion-resistant, insoluble in water, and has strong resistance to corrosion by both acids and alkalis. The upstream feedstock of this product is titanium ore, and downstream it is the core key intermediate raw material for producing high-grade titanium dioxide pigment, smelting ferrotitanium alloy, and preparing titanium metal. It is widely used in aerospace, chemical industry, metallurgy, and building materials, and is an important fundamental mineral product for the development of the titanium industry. 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
The entire production process uses raw ore to select titanium concentrate and iron concentrate through crushing, ball milling, raw ore pulping, "magnetic separation + gravity separation" and other processes. The entire process covers the process from titanium ore to titanium concentrate.
Process Description
Ilmenite concentrate is a high-grade titanium-containing mineral product obtained after beneficiation and purification of titanium ore. Its main component is titanium dioxide. The TiO2 content in the titanium concentrate is 41.82%, which is equivalent to a Ti grade of 25.1%. The appearance of titanium concentrate is mostly black or dark gray powdery or granular material, with a certain metallic luster and high specific gravity. It has stable chemical properties, is resistant to high temperatures and corrosion, is insoluble in water, and has strong corrosion resistance to acids and alkalis. Due to its high purity and low impurities, titanium concentrate is a key intermediate raw material for producing high-grade titanium dioxide pigments, smelting ferrotitanium alloys and preparing titanium metal. It is widely used in aerospace, chemical industry, metallurgy, building materials and other fields.

The raw ore is used to produce titanium concentrate and iron concentrate through processes including crushing, ball milling, raw ore pulping, and “magnetic separation + gravity separation.” The raw ore is transported to the stockpile yard for storage. After crushing, the ore is sorted in the first-stage chute, and the resulting concentrate enters the second-stage chute for further sorting. The middlings and tailings undergo two-stage magnetic separation; the magnetic products proceed to the second-stage chute sorting, while the non-magnetic products are discarded as tailings. Among the products from the second-stage chute sorting, the middlings and tailings pass through a screening grid. The undersize material is returned to the first-stage chute for re-sorting, and the oversize material is discarded. The concentrate from the first-stage chute sorting is fed into a ball mill for first-stage grinding and second-stage regrinding for beneficiation. The products from the first- and second-stage grinding first undergo low-intensity magnetic separation to obtain magnetic minerals as iron concentrate. The non-magnetic products from the first- and second-stage low-intensity magnetic separation enter the third- and fourth-stage chute sorting. The concentrate from the fourth-stage chute sorting is subjected to high-intensity magnetic separation. After sedimentation, the settled product from the magnetic minerals is obtained as titanium concentrate, and the overflow returns to the fourth-stage chute sorting. The middlings from the third- and fourth-stage chute sorting are sequentially returned for re-separation. The tailings, together with the non-magnetic products from the high-intensity magnetic separation, enter screening. After removal of coarse particles, the undersize material is returned to the first-stage chute for re-sorting, and the oversize material is discarded.
