Lixiviation mills, developed in the 1880s, leached complex ores with a solution of sodium or calcium hyposulfite and occurred throughout the West in the late nineteenth century. The development of the cyanide leaching process in Scotland and New Zealand in the late 1880s, however, revolutionized ore processing and spread rapidly throughout

Although the early iron industry used bog ore to obtain iron, ironstone is the most common iron ore and it is extracted from open cast (surface) sites in England, from the River Humber to the River Severn. To obtain iron from ironstone the ore is first roasted with coal. This process is called sintering.
