Is metal a renewable resource?

3 Comments

Or non renewable? If it’s non renewable, then why aren’t people getting worried that it’s supply will be exhausted? Unlike fossil fuels- which many people are concerned about.
The metals are constantly being produced in the heat and magma underground so it shouldn’t run out.

    A renewable resource is replenished by natural processes at a rate comparable or faster than its rate of consumption by humans or other users.

    Renewable Resources include oxygen, fresh water, timber, and biomass. However they can become non-renewable resources if used at a rate greater than the environment’s capacity to replenish them.

    So the metal comes in Un-Renewable Resources.B’coz it is used at an aquifer at a rate greater than the sustainable recharge.

    But I thing there is not required for worried about their ends, B’coz metals are not destroyable & they may be remelted from one form to another form & reused.

    Thanks ! ! !

    Einstein says matter cannot be created or destroyed.The Earth no doubt already contains considerable amounts of elemental metals,but when last did they open a mine next to a volcano? If you filter enough seawater you`ll find gold and assorted polluting heavy metals but in such tiny amounts its not economically viable to collect.Typically it takes about 5 tonnes ore to produce 1t iron-not to mention 20t coal to smelt it.Some metal ores have a much lower yield.There must be enough empty coke cans scattered about the countryside to rebuild the Titanic,but imagine the cost of collecting them all together?
