Increasing depletion of mineral resources
In our earth, there are a large number of resources, but in these, there are a lot almost drain.Some resources are renewable resources,such as water resources and forest resources can reuse, but Mineral resources which requires almost a thousand years after the evolution of even a few years in order to be our exploitationis.
At present mineral resources has become increasingly depleted, so we need more rational exploitation.
Here are many subjects that is about some resources.
Useful minerals can use to industrial and agricultural which Will become a fossil coming together in the earth's crust or the surface.
Mineral resources is an important natural resources, belonging to non-renewable resources.One of copper, lead and zinc is rich,And bauxite and other minerals is the lack of focus.
Reasonably exploit and utilize mineral resources is very important,this is my idea about protection of mineral resources:Firstly,to recognize that mineral resources are non-renewable resources so that care and rational use limited resources.Secondly,should be resolutely put an end to destructive mining.Thirdly,Use of lean ore to improve the relevance of using of the overall development.
China's mineral resources has been found
Resources found in China
China has proved the world's total mineral resources account for about 12% of the world 3. Less per capita, the world's per capita is only 58%, ranking first in the world 53. As of the end of 1998 China has discovered 171 kinds of minerals, or minerals found in the vast majority of the world. Proved the total resources are 155 kinds of minerals.
Eight kinds of Energy and Mines 54 kinds of metal ores 90 kinds of non-metallic mineral Three kinds of mineral water Tungsten, tin, molybdenum, antimony, rare earth, fluorite, barite and other mineral resources in the world. Oil, natural gas, uranium, iron, manganese, chromium, copper, bauxite, gold, silver, sulfur, potassium and other mineral resources of the world's total volume is relatively low. According to projections, China's petroleum, iron-rich, the rich manganese, copper, chromium, potassium and other mineral resources for a long period of time can not meet domestic demand.
Resource distribution in China
Oil and natural gas are mainly distributed in northeast, north and northwest Coal mainly in the north and northwest Iron mainly distributed in northeast, north and south-west Copper are mainly distributed in southwest, northwest, east all over the country lead-zinc; Tungsten, tin, molybdenum, antimony, rare earth ore are mainly distributed in South China, North China; Gold and silver mine located in the country, Taiwan is also an important source Phosphate mainly in southern China
