Is iron ore a renewable resource?
Iron ore is not a renewable resource.Iron ore is an important raw material for iron and steel production enterprises. Natural ore (iron ore) is gradually selected by crushing, grinding, magnetic separation, flotation, gravity separation and other procedures. A mineral aggregate containing iron or iron compounds that can be economically used.
Iron ore is not a renewable resourceNatural gas, oil, coal, iron ore and other mineral resources are non renewable resources, they are less with some, it is impossible to re produce. Taking iron ore as an example, it is a long geological process for iron elements to be combined with ore deposits with industrial value. They were formed in the Archean era of 26~30 billion years ago. In ancient times, the mineralization period was calculated in millions of years. On the contrary, human exploitation and consumption of minerals are very rapid. One mine is only one hundred years, decades or even several years. Therefore, from the perspective of human history, mineral resources are non renewable. In addition, renewable resources may become non renewable resources if they do not pay attention to conservation and arbitrary access. For example, a wild animal, once its living environment is destroyed, reduce the number of species to a certain extent, it is impossible to sustain their reproduction, only dinosaur extinction, is disappearing from the earth. According to statistics, since 1600, 724 species of higher animals and plants have been recorded. After a rough estimate, in 400 years, the living environment has shrunk by 90%, and the species has been reduced by half. The tropical rainforests have been cut down, which has a greater impact on the loss of species. Therefore, whether it is non renewable resources or renewable resources, we should pay attention to protection and rational use.
It mainly includes biological resources (renewable), land resources, hydropower, climate resources and so on. Is the use, consumption and processing, combustion, waste and other procedures, in a certain period (predictable) repeated formation, self-renewal and recovery characteristics, a kind of natural resources and sustainable use, corresponding to non renewable resources, sustainable development is to strengthen the construction of and promote the use of clean energy.
Renewable resources refer to resources that can be reused or can be regenerated or reused in a short period of time.
