“Like China is seeking iron ore resources outside of Australia and Brazil, the United States, Asia and Europe are also seeking rare earth resources outside of China.†In the face of global demand and China’s monopoly, Australian mining companies Manager Dudley made an analogy.
At the 6th International Symposium on Rare Earth Development and Application and the First Rare Earth Summit held yesterday, the supply and demand of rare earths was expected to be the focus of the discussion. As China's rare earth supply cannot continue to meet global demand, other countries have begun to restart the mining of rare earth resources. However, the industry said that the price control of rare earths is still in the hands of China.
Rare earth supply shortage leads to increased global mining
“China's rare earth accounts for 20-30% of the world's reserves and responds to 90% of supply, which is difficult to sustain in the long run.†Zhang Anwen, deputy secretary-general of the China Rare Earth Society, said that countries should make more use of the safety of rare earth resources. Rare earth resources in other countries.
For this strategically important metal variety, China is adopting a cut in export quotas to restrict the export of some products, and the export price of rare earth has also increased since 2007. In 2010, China’s export quota was around 30,000 tons, but the world’s demand reached 48,000 tons. Under this situation, countries such as the United States, Russia, India and Southeast Asia are re-increting or increasing the mining of rare earth ore. Australian mining company Dudley expects that by 2015, the supply and demand of rare earths will reach a basic balance.
“We are very welcome to increase the supply of rare earths in foreign mines. If China's supply can be reduced from the current 90% to around 60%, it will be a good supply and demand structure.†Hu Boping, Senior Vice President, Zhongke Sanhuan (000970) In an interview with this reporter during the meeting, China said that China does not have to worry that foreign mines will change the supply and demand pattern and affect the price of rare earths, because in fact the price control of rare earths is firmly in the hands of China. The increase in the supply of international rare earth resources will greatly reduce the export pressure of Chinese mines.
Short-term application of fluorescent materials is restricted
As another hotspot in the application of rare earths, the fluorescent materials market has received much attention. However, many experts and business representatives admitted to the reporter that since the use of rare earth materials in LEDs is very small, although the LED market will achieve rapid development, in fact, the utilization of rare earths is still very limited.
However, the long-term application prospects of rare earths are still optimistic. At present, the application of rare earth in China's new materials sector accounts for about 50%. According to estimates, by 2020, the global production of new energy vehicles is expected to reach 13 million. China's wind power installed capacity will be greatly increased to 150 million kilowatts, and nuclear power installed capacity will be 80 million. Kiln, coupled with the development of industrial motors, civil appliances, 3C products, etc., the rare earth raw material industry will be pulled up and upgraded.
Accessories for cameras are mainly for care, protection, special effects and functions.
Lens hood: used on the end of a lens to block the sun or other light source to prevent glare and lens flare (see also matte box).
Lens cap: covers and protects the lens during storage.
Lens adapter: sometimes called a step-ring, adapts the lens to other size filters.
Lens filters: allow artificial colors or change light density.
Lens extension tubes allow close focus in macro photography.
Flash equipment: including light diffuser, mount and stand, reflector, soft box, trigger and cord.
Care and protection: including camera case and cover, maintenance tools, and screen protector.
Large format cameras use special equipment which includes magnifier loupe, view finder, angle finder, focusing rail /truck.
