The South Staffordshire Coalfield…
(1859)
“ The quantity of coal required for calcining and for smelting the iron ore is at the rate of about three tons of coal for one ton of iron, or about 1,793,427 tons were employed in 1858 for that purpose. This is exclusive of the coal required for the manufacture of bar iron, &c. The quantity of ironstone raised from the South Staffordshire coal measures, was about 959,000 tons; the average production of iron from this ironstone ore being about 33 per cent. ”
