Daye is an industrial city, a center of mining and metallurgy, both ferrous and non-ferrous; its name means 'developing a prosperous smelting industry' (大兴炉冶).

Copper mining and smelting was conducted at Daye's Tonglüshan Mine (铜绿山, 30°04′52″N 114°56′07″E) as early as the Spring and Autumn period (6th century B.C.E.), if not earlier.
Tonglüshan Mine is located just southwest of the modern city, and now has a museum.

Although such copper-containing minerals as malachite and azurite are found here, the local ores are richer in iron than in copper, and the modern Daye is better known for its iron ore mining and processing.

Among the major employers is Huangshi Daye Non-ferrous Metals Co., Ltd.
