Use of Blast Furnace Slag as Mining Fill

The investigation was carried out by using different amounts of blast furnace slag in blended cements. The slag content of the binder varied from 0 % to 100 % of the weight of the cement. The cement-aggregate ratio in the experiments was 115 and the water-cement slag ratio was 5.9.

History of lead mining Minerals and mines Foundations

The 19th century was a period which saw Cornish mining technology used to deepen some of the mines in search of richer ore deposits. However, as the lead veins narrow with depth, this proved unsuccessful, and attention was switched to resmelting the lead-rich waste slag and slimes left over from previous medieval mining.
