Austria has unusually diverse mineral resources for a small country. It is the world's largest producer of magnesite. There are also significant deposits of lignite and iron ore and smaller deposits of wolfram, antimony, gypsum, graphite (lower grade), dolomite, talcum, kaolin, quartz, and salt. Minerals are found throughout the country, but most significant deposits are in Styria or in northeastern Austria.
Mineral production accounted for only about 2 percent of GDP in 1990, having declined steadily in economic importance since World War II. However, it remains a significant source of income and employment in certain mountainous areas and in 1991 consisted of 109 firms employing about 6,700 persons. The principal mineral products in 1990 were lignite (2.4 million tons), iron and manganese (2.3 million tons), magnesite (2.0 million tons), gypsum (753,000 tons), and kaolin (474,000 tons).
