Guangzhou waste aluminum recycling Guangzhou waste aluminum recycling environmental pollution, mainly in the smelting process of dust, from the actual situation of the use of waste aluminum in China, there are indeed serious environmental problems. However, at the speed of China's development, this problem will be eliminated sooner or later. Compared with the utilization of waste aluminum in developed countries, the quality of recycled aluminum in China is generally poor, and there is a waste of resource allocation and use. Although the output of China's twin aluminum has reached 1.3 million to 1.5 million tons, China's existing recycled aluminum smelting plant is mainly small and medium-sized enterprises, and its scale, equipment and testing capabilities are low. Unlike 80% of recycled aluminum in the world, which is absorbed by the automobile industry, the main sales areas of recycled aluminum products in China are mainly for the aluminum and civilian products cast aluminum industry. Most enterprises are difficult to adapt to the requirements of the automotive industry for high-grade cast aluminum materials due to technical and management problems.
Edible
salt, also called Table Salt or just salt, is a mineral, one of a very few mineral substance commonly
eaten by humans.
There are different forms of Edible Salt: unrefined raw salt, refined salt,
table salt or
iodized refined salt. It is a crystalline solid, white or

rock
deposits. Sea Salt comes in fine or larger crystals. In nature, it
includes not only Sodium Chloride,
but also other vital trace minerals.
Edible rock salts may be slightly greyish in colour due to this mineral
content.
