Steetley Pier Hartlepool 1 (1 of 1)

Steetley pier Sea water was pumped to the Magnesium plant. Steetley extracted magnesia from sea water by reacting it with dolomite.
Hartlepool was selected as the site for the factory because of its location close to the high purity dolomite deposits at Coxhoe and the fact that the seawater was of consistent quality and free from dilution by fresh river water. It was also near the Durham coalfield which provided the fuel for the kilns. Refractory grade magnesia is used in the manufacture of refractory bricks, tiles and gunning materials for application in steel, cement and non-ferrous industries. Chemical grade magnesia is used in the manufacture of rubber, plastics, leather, oil, paper pulp and fertilisers. Steetley closed in 2005 after two failed attempts to keep it going.
