In recent years continuous processes (continuous casting) for the production of rod (CCR) have been successfully developed. This has meant that new rod plants must adopt this technology, and that cathode copper rather than wirebar is becoming the dominant form of traded copper , as cathode copper is used directly in CCR rod production. World CCR productive capacity has increased from 200000 tpy in 1965 to over 5 million tpy in 1980. Ninety-two per cent of this capacity is in developed countries.

Green-charged reverberatory fumaces consume large amounts of fossil fuels and produce large amounts of sulphur dioxide which is vented to the atmosphere. This environmental problem has led to smelting processes which are less polluting.
Other production factors such as the possible introduction of electric cars, when the copper content fcer auto could increase from 20 kg to 100 kg 0, might make the projected increase a conservative one. Solar heating could increase the use of copper in building construction. On the other hand, optical fibre cables and microwave communications will replace copper in some telecommunications uses. Short-term demand for refined copper will, of course, be affected by the current world-wide recession.
