Grecian Magnesite T he village of Yerakini in Chalkidiki, northern Greece, is the base of a major mining concern. Grecian Magnesite's presence in Chalkidiki goes back to 1914, when mines at Vavdos and Troupi were first developed by the distinguished engineer J. T. Lambrinides. In 1959, the company was acquired by the Portolos family. Today, it remains a family company and employs about 320 people. Grecian Magnesite's interests reach beyond Greece: it has a 40 per cent stake in the Spanish mining company Magnesitas Navarras S. A.; and in 2007 the company acquired a 50 per cent stake in Van Mannekus & Co., a leading trader and processor of magnesite and other industrial minerals, based in Schiedam, the Netherlands. Grecian Magnesite also has a Turkish subsidiary company, Akdeniz Mineral Kaynaklari A. S., which has substantial magnesia reserves and production capacity. Magnesite is magnesium carbonate ( MgCO3). In Chalkidiki, Grecian Magnesite extracts the mineral ore through open- cast mining. Magnesite often contains traces of iron, giving it a grey or brown colour, but because the magnesite deposits in Chalkidiki are unusually pure, their colour is white- and the Greek name for magnesite literally means ' white stone'. The raw magnesite produced by Grecian Magnesite has several industrial applications. However, even raw magnesite must be processed before it can be made suitable for industrial use. After mining, most of the gangue ( the worthless rock) has to be removed. Grecian Magnesite does this through laser- scanning technology, using 11 photometric ( light- measuring) ore sorters. The ore is then ready for beneficiation ( the process of concentration of its mineral content), when it can be separated from the gangue that is left and then sorted according to different grades of quality. The company's pre- beneficiation and beneficiation plants are both located at Yerakini.
