Acid Mine Drainage: Chemistry COTF
Acid Mine Drainage: Chemistry. Because they are strong bases, they ionize and dissolve in water. The resulting hydroxide (OH ) and carbonate (CO 32) ions combine with hydrogen (H+) ions, taking them out of solution. The resulting products are water (H + + OH <> H 2 O) and carbonic acid (H 2 CO 3 )....

The lead legacy
The organisation of the mining industry includes a complex series of laws and customs, which were first codified on paper in the Quo Warrento of 1288. Even by this date they were already ancient and may well have evolved in late Anglo Saxon times. Lead mining in Derbyshire has been overseen by the miners' Barmote Courts since medieval times....
