They will contribute greatly to the fugitive dust emissions from the plant. Our estimation shows that annually about 10,000-20,000 tonnes of fugitive dust can be released from coal and bauxite storage site alone to the surrounding environment.
The existing ambient air quality, in terms of Particulate Matter- 10 (PM- 10), Particulate Matter- 2.5 (PM-2.5), Sulphur-dioxide (SO2), Oxides of Nitrogen (NOx), and Carbon Monoxide (CO), has been measured through a planned field monitoring. Bauxite mining is carried out by opencast manual method.
The detailed analysis on the impact of the plant on the air quality is represented below. Fugitive dust: Bauxite and coal, which constitutes more than 95% (9.9 million tones annual consumption) of the total material for this project are proposed to be stored in open. They will contribute greatly to the fugitive dust emissions from the plant
The booming bauxite mining industry and export from Guinea may change the International bauxite market as lower grade bauxite of India, Indonesia and Australia may face new challenges. China’s declining domestic bauxite output due to inferior quality and high cost of mining continues to accelerate bauxite imports. In 2019, China imported about 100 million tons of bauxite mainly from Guinea, Australia and Indonesia. At presently imported bauxite in China is cheaper than domestic ore and

The greenhouse gas emissions from alumina production are predominantly related to fuel combustion; therefore improved energy efficiency along with fuel switching, where viable and appropriate, is the primary means of reducing the greenhouse gas intensity of refining processes, which currently stands at around 1 tonne of CO 2 e per tonne of alumina produced.
Bauxite is a rock that is mainly composed of various minerals. Most importantly, bauxite is the primary ore for aluminum. Aluminum is a very crucial element as its uses are varied and diverse
Bauxite mining has indeed caused pollution around Bukit Goh, Gebeng and the Kuantan Port. For months, certain areas in the district - particularly Bukit Goh - have suffered serious air pollution
According to Mr. Lyew-You, dust nuisance was the main complaint from persons living in bauxite communities, but through a Memorandum of Understanding (MOU) with the National Environment and Planning Agency (NEPA) in the late 1990s, in which the Institute agreed to monitor the bauxite companies on behalf of the environmental agency, emissions have been reduced by an average of 26 per cent annually. In bauxite mining, activities such as site clearance and road building, open-pit drilling and blasting, loading and haulage, vehicular movement, ore and waste rock handling generate dust particles can react with the air in atmosphere, causing various chemical reactions, affecting soil, hence health of plants; dust can also dissolve in water from where it is ingested by humans or aquatic animals. Heavy mining activities which have been carried out aggressively contaminates water, especially
