Iron ore pellet screenings
Iron ore pellet screenings are generated during particle-size classification of the pellets produced.
The advantages of screenings include their high Fe content, consistent chemical composition, and low levels of harmful impurities.
They are used as a raw material for sintering production.
The final dimensions and characteristics are agreed with the customer individually

Storage, transportation, delivery conditions
| Minimum order | 69 tonnes (delivery by hopper cars) |
| Transportation requirements | All types of transport modes can transport pellets, as long as it is in accordance with the transportation requirements for each specific mode of transport. Pellets can be transported in bulk, in conditions safe from contamination and mixing with other materials, as well as in conditions that avoid cargo spillage. |
| Storage requirements |
Should be stored in conditions safe from contamination and mixing with other materials.
Freeze-proofing measures (shoveling, application of special anti-freeze solutions, etc.) shall be taken during cold season, if required. |
| Notes |
To reduce losses of pellet screenings during transportation, it is advisable to add iron ore concentrate on the bottom of the rail car to form an even layer of up to 10% of the car load capacity. It is allowed to transport pellets with a total iron content deviation of 2.0%. This amount should not exceed 10% of the monthly supply volume of each customer. |
