An overview of generic melt circulation technology was presented at a Canadian Institute of Mining, Metallurgy and Petroleum conference in 1996.
To overcome limitations in current technology and to open the door to breakthroughs in the extraction and recycling of metals, melt circulation within closed loops is proposed. The general features of generic melt circulation technology, particularly for massive reductions in energy consumption, are highlighted. Reference is made to the recently published paper on lower-energy primary aluminum. More detailed attention is then focused on coproduction of steel and titanium metal directly from ilmenite concentrates. The energy consumption is projected to be less than one third of the best available technology (Kroll process). Next, new copper smelting concepts based on melt circulation are introduced because current advanced processes are judged to be, without exception, energy inefficient.

What heat energy is used to melt metal ores and where does it come from?
JAMAICA
What produced the heat energy used to melt metal ores?
fire
Where did heat energy used to melt metal ores come from?
Burning charcoal, wood and coal.
Why do you mine metal ores?
Metal ores are used as resources from which metals may be extracted.
Is energy saved if we recycle metals?
Yes, you save all the energy that would have been needed to mine fresh ore from the ground and to extract the metal from that ore. The amount of energy needed to collect and sort the recycled metals is insignificant compared to this (especially for metals like aluminum that are very hard to extract from their ores).You only need to use the energy needed to melt the pure metal, which you would have needed anyway after extraction of new metal from fresh ore.

Are metal ores synthetic?
No, metal ores occur naturally in the Earth.
Is aluminum a renewable fuel?
No, aluminum is a metal. It needs large amounts of energy to extract it from its ores.
Why do you mine metal ores?
Metal ores are used as resources from which metals may be extracted.
Why aren't metal ores useful?
Metal ores are refined into metal. Metal is very useful, hence, metal ore is also useful.
What are factories that make metal ores called?
Factories do not make metal ore. A refinery or smelter makes metal from metal ores.

Does metal come from ores?
From various minerals and ores which are mined. Which metal depends on which mineral is mined.
What is oxide ores?
Those ores which contain metal in the form of oxides are called as oxide ores.
