Some observations on copper yields and ore grades
The south-west of England (Cornwall and Devon) was its most important copper mining region. Appendix Fig. A1 shows the trend in the five-yearly average percentage yields of its copper mines from 1770 to 1900. Average grades declined until the early 1860s, but then rose slightly in the remaining decades of the nineteenth century.
