Russia’s United Wagon Company (UWC) has signed an agreement to supply Polymetal with 55 dump cars by the end of H1 2020.
Polymetal is a top 20 producer of gold and a top 5 producer of silver globally, and the company holds assets in Russia and Kazakhstan.
The batch of rail cars will be delivered to the Varvara plant for operation in Kazakhstan.
Varvara, Polymetal’s first operation in Kazakhstan, is a gold and copper mine with a modern 4.2 Mtpa processing plant. Excellent transport infrastructure and inexpensive energy make it ideal to become a regional processing hub. Today, Varvara comprises of an open-pit gold mine and the Komarovskoye gold deposit.
The UWC dump cars are designed for transporting and automatic unloading of overburden and hard rock. The 32-6982 model railcars will have a shock-absorbing floor, increasing resistance to the shock loads encountered when loading/unloading large rock fractions, thereby preventing damage to the car.
UWC said that, compared with a popular market competitor, the rail car has an increased payload capacity of 71t and a volume capacity of 42 m3, allowing for a load increase of up to 10t.
“The dump car can be coupled to a freight train of any type, and run on the existing rail infrastructure of shippers and recipients,” said UWC. “The side opening mechanism and pneumatic unloading system allows tilting the car body at an angle of 45 degrees to either side with the sides opening simultaneously followed by its return to the upright transport position.
“The car runs on the 18-9855 bogie with a 25t axle load, which extends its overhaul mileage and reduces significantly operating costs over the dump car’s entire life cycle of 32 years. For comparison, a similar standard freight car’s service life is only 22 years, being 10 years shorter.”
Igor Nikolishin, managing director at Polymetal Varvara, said: “We are operating at our full production capacity. We have to meet strict time and sequence requirements in our extraction, transportation, and processing activities.
“Moreover, the nature of our business implies working with large and heavy fractions of rock and so, when choosing a railcar supplier, we do focus on technical specifications and design reliability of their products. Dump cars manufactured by UWC meet our requirements.”
