• Resumen

  • The design consists of two 44.5 km, 600-700 mm diameter welded steel-plastic lined pipelines with a capacity to transport up to 20m tpa of polyhalite. The first pipeline is a slurry concentrate pipeline transporting the polyhalite ore from the mine to the proposed processing facility at Teesside. The second pipeline will return the transport water back to the mine site, effectively forming a closed loop system.

    Running adjacent to the pipelines will be a power cable, fibre optic cables for control systems, and a leak detection system. At the mine, there will be a slurry preparation terminal comprising of ore crushing, milling and mixing tanks. At Teesside, receiving tanks will prepare the ore for processing. Pipeline test work has concluded that material can be pumped as slurry from the mine to Teesside from one pumping station located at the mine.

    Sirius commissioned GBM to evaluate the feasibility of producing NPK (nitrogen, phosphorous and potassium) fertiliser, with polyhalite as the primary source of potassium. The NPK plant was designed as an addition to the granulated polyhalite processing plant with 1m tpa modules allowing for flexible expansion up to 5m tpa of NPK.
