Hungarian incidents and bauxite lessons with Vietnam

Bauxite residue (red mud) is a liquid waste containing metals, which can pose a potential risk to human health. Discharging and storing red mud is a top concern in the process of bauxite processing and exploitation. The valuable lessons for our country come from the story with the Hungarian Secretary of State.

Consequences of Hungarian red mud incidents

Bauxite processing industry - Alumina, Hungary's pride for a while. But the environmental protection has not been focused, so it has caused an environmental disaster incident.

The new Greenpeace environmental prototype, released on October 12, said at least three areas were overflowing with red mud, which contained dangerous toxins to the environment and people. In addition to high arsenic levels, scientists found that some of the higher-level metals were normal antimony, nickel and cadmium in Ajka city and the surrounding area.

Scientists have tried dust at Devecser. During the windy day, the level of toxicity is much higher than the normal level. Antimony, a cancer-causing chemical is three times higher than permitted. Nickel, an allergen and cadmium, can affect fertility and the nervous system is also found in the soil, the area where rescuers use fertilizer to detoxify in mud.

Scientists emphasize that the current level of arsenic is the most disturbing issue and criticizes the Hungarian government for not having a mechanism to check the level of environmental safety in places where red mud spills out. The World Health Organization has also sent staff to support this country.

Precious experience for Vietnam

A few days ago, this article writer had a chance to meet a Hungarian official, Mr. Throweth Zsolt, the Secretary of State from your country, saying: 'This afternoon I have just had a meeting with the Minister and his Minister Vietnamese diplomacy. Which mentioned that this December, Hungary will invite a delegation of Vietnamese officials to survey the situation. We will tell all the causes of the incident, how to fix it; Experience building safe red mud reservoir. Especially proper attention to environmental protection '.

With the question: ' Can you elaborate on red mud troubleshooting? 'The Secretary of State answered:' Hungary has established a Troubleshooting Committee, to ensure that the people are above all. Ensure stability and cleaning as soon as possible. Of course, it takes a year to clean up, especially the funding problem. Man-Rt, the aluminum manufacturing and trading company, is fully responsible and will make adequate compensation '.

Mr. Throweth Zsol also revealed: ' Of course, carbon dioxide cannot be used at this time, and seawater cannot be used to neutralize red mud. Hungary has used gypsum to neutralize the currents, so that the concentration of alkali decreases to pH ".

Finally, learning about 'the possibility of recovering farmland ,' Mr. Throweth Zsol said: ' Hungary will back off about 1,000 hectares of land - replacing the soil on the surface about 2-10 centimeters .'

From the incident of Hungary, our country can draw many valuable lessons about exploiting and processing bauxite - alumina.
