Mineral reserves and mineral quantity are two different things. Without significant progress in geological survey technology, there are only a few places in Sweden. Where can it increase the proven mineral resources? Science in Sweden is very developed. A Nobel Prize saved China for a century.

In addition, the statistical caliber is different and the data is different. There are several concepts such as iron ore, ore iron/basic reserves and proven reserves.

In Sweden, iron ore is the most abundant mineral resources, and the proven iron ore reserves are about 4 billion tons, ranking third in Europe. Iron ore is mainly distributed in Lapland at high latitudes in the north, with three quarters concentrated in Kiruna and Yeliwal. The iron ore produced in this area has a high iron content of 60%-70% and a low phosphorus content, which is the key raw material for producing high-quality steel. Yerevale is known as the "mining capital" of Europe, which not only contains huge amounts of iron ore and copper ore, but also is accompanied by mineral resources such as gold and silver.

Sweden is the largest exporter of iron ore in Europe, and its northern mining areas provide 95% of exports and 60% of domestic consumption. With abundant iron ore resources, Sweden has gradually developed industries such as mining and metallurgy, special steel smelting, machinery and equipment, and precision instruments, which has spawned a large number of Kiruna Iron Mine Company (LKAB, 1890), SKF Bearing Company (SKF, 1907), Volvo Car Company (1927) and so on.

In addition to iron ore, Sweden's proven uranium reserves are 250,000-300,000 tons. In addition, there are minerals such as sulfur, copper, lead, zinc and arsenic in the northern and central regions, but the reserves are small.

At present, only 10 countries in the world have established a strategic mineral reserve system, and Sweden is one of them.
