COPPER Copper production

Copper concentrators typically treat up to 100 000 t of ore per day They are located directly at the mines to achieve low transport costs The copper recovery efficiency is over 90 % About 95 % of the ore input goes into the tailings which are stored in large dams near the mine and are used for water recycling to the flotation stages

Iron and Steel

But one important advantage of cast iron is that it can be made into large beams rather like wood: it does not have to be used in blocks like stone So the designer of the Coalbrookdale bridge made the cast beams to fit together like wooden beams: the ends were shaped so that they could mesh together just like the joints on a wooden structure and the joints were pinned with dowels (Figure 2)

Iron ore pricing explained

Different percentages of iron content reflect both the natural variation in iron ore grades found in mine deposits and the degree of processing (if any) employed to upgrade the ore for a certain use In general higher purity ores help increase hot metal yields in the blast furnace and also lower production cost by reducing the amount of coke required
