Authoritative PPT Summary
"Rocks, Minerals and Us" Rocks and Minerals PPT Courseware 2
The development of human society and the progress of science and technology are inseparable from the development and utilization of mineral resources. Starting from the ancient Stone Age, passing through the Bronze Age, Iron Age, and Steel Age, and developing to the Petroleum Age and Silicon Age, with the development of production and the advancement of science and technology, the types of mineral resources discovered and utilized by humans are becoming more and more important. There are many, and the scope of application is getting wider and wider.
my country has discovered 171 kinds of minerals and is one of the few countries in the world with a relatively complete range of minerals. Among them, the proven reserves of more than 20 kinds of minerals, including rare metal ores, tungsten ores, and tin ores, rank among the best in the world.
my country's total mineral resources rank second in the world, and it is also one of the earliest countries in the world to pioneer the mining industry.
Although the types and total amount of my country's mineral resources rank among the top in the world, the per capita share is only 58% of the world average, ranking 53rd in the world. Some mineral types even rank behind the 100th in the world.
Do you know what mineral resources our hometown will have in the future?
Zhejiang’s mineral resources are mainly non-metallic minerals. The reserves of stone coal, alunite, pyrophyllite, cement tuff, and construction tuff rank first in the country, and fluorite ranks second in the country. The East China Sea continental shelf basin has good prospects for oil and natural gas development.
The most famous ones in Zhejiang are "ten stones and three handfuls of soil", namely fluorite, alunite, limestone, granite, marble, pyrophyllite, wollastonite, zeolite, perlite, illite and diatomaceous earth, bentonite and kaolin.
There are a lot of "treasures" underground in Taizhou, and there are even several metal mineral resources that rank first in the province in proven reserves.
The city's proven resource reserves of lead, zinc, and silver-based metal minerals rank first in the province, and it is an important metal mineral producing area in the province. As of the end of 2009, the city's resource reserves were nearly 810,000 tons of lead, more than 1.2 million tons of zinc, and more than 1,000 tons of silver.
There are also a lot of fluorite reserves that are comparable to rare earths, and the reserves of building stones are even bigger.
Rocks and minerals are important materials that make up the earth and are also valuable resources for people's production and life. Once they are mined, they cannot be regenerated, so we must protect and rationally utilize rocks and minerals.
my country's Mineral Resources Law stipulates that mineral resources belong to the state and no organization or individual may exploit them privately.
Think about it: How do people mine, utilize and protect mineral resources around us?
