The principal minerals produced in South Dakota, in terms of value, are cement, gold, crushed stone, sand and gravel, and lime. In 2003 cement overtook gold as the state’s most valuable mineral commodity.
Although it is a low-ranking state in value of total mineral production, South Dakota was long a leader in gold production. Much of the gold produced in the United States came from the Homestake Mine in the Black Hills, which closed in 2001. Much of the state’s gold now comes from open-pit mines. Sand and gravel are produced in almost every county. Granite, quartzite, and limestone are quarried in many of the state’s counties.
The production of foodstuffs long ranked as the principal industrial activity in South Dakota. But by the mid-1990s the manufacture of machinery generated the biggest share of personal income for state residents. Industrial machinery provided two-fifths of South Dakota’s value earned from manufacturing as a whole. Leading machinery industries include manufacturers of computers, office equipment, and machinery used in construction.
The processing of food products remains an important activity. Much of the annual output of foodstuffs is made up of meat and meat products, which are produced in plants in Sioux Falls, Watertown, Huron, Mitchell, and Rapid City.
Other food-processing activities in the state include flour milling, baking of breadstuffs, production of dairy products, and poultry dressing and processing. Other industries employing significant numbers of people were companies producing electronics, printers and publishers, lumber mills, firms making storm doors and other metal components for buildings, medical instruments, truck-trailer manufactures, scoreboards, and the jewelry industry.
