mineral.) Harvey and Press note that prior to 1870, Britain was selfsufficient in iron ore, copper, lead and tin, and "Britain was easily the most important mining nation in the world" (1990, p. 65). US lead mine production did not surpass that of Britain until the late 1870s. Leadership in coal came even later.
