The primary risks of this activity are dust pollution, vegetation loss, forest fragmentation and biodiversity loss, negative impact on water resources, creation of wastelands, and social impact. Bauxite mining is one such significant open cast mining activity that has a significant negative impact on the local environment.

The effects of dust on crops, grasslands, heathlands, trees and woodlands, arctic bryophyte and lichen communities are identified. Dust may affect photosynthesis, respiration, transpiration and allow the penetration of phytotoxic gaseous pollutants. Visible injury symptoms may occur and generally there is decreased productivity.

The main environmental problems associated with bauxite mining are related to the rehabilitation of mined-out areas and the disposal of tailings. Emissions of dust consisting of clay and bauxite particles from dryers' chimneys can also pose problems. Brazil's largest bauxite mine, the MRN mine in Oriximina

Roads in quarries are often sprayed with water, especially in summer to reduce dust and internal route-ways are maintained and often surfaced to minimise expensive tyre wear and again, to reduce dust. Rubber and plastics are increasingly used to reduce wear on metal parts and lessen noise in vehicles and plant.

In mining and quarrying, water is used and gets polluted in a range of activities, including mineral processing, dust suppression, and slurry transport. In addition, water is subtracted from the environment in the process of dewatering, the process of pumping away the water that naturally flows into the pit or tunnels of the mine.

Conclusions: These preliminary findings, based on very few cases, suggest that cumulative inhalable bauxite exposure may be associated with an excess risk of death from non-malignant respiratory disease and that cumulative inhalable alumina dust exposure may be associated with an excess risk of death from cerebrovascular disease.

Bauxite dust is detrimental because it can decrease visibility and result in visual changes to the environment8. It can be deposited into machinery, reducing their life cycle and overall productivity. Bauxite dust is inhalable (respirable), and defined as dust particles less than 10μm in diameter or particulate matter of PM10and PM2.510.

Noise, dust and the vibration caused by the regular passage of HGVs have the potential to damage the fabric of historic buildings, monuments and areas. Such traffic can also diminish our opportunities to enjoy and appreciate these assets. The surface disposal of mineral-working waste can prevent (or reduce) appreciation of historic sites.

No one can question the enormously positive impact that the bauxite/alumina industry has had on the Jamaican economy over the last 53 years. The sector is today the second largest foreign exchange earner, raking in some US$901 million last year (an 18 per cent increase over 2003), and creating significant linkages in the economy as well as providing quality …

Mining and quarrying can be very destructive to the environment. They have a direct impact on the countryside by leaving pits and heaps of waste material. The extraction processes can also contaminate air and water with sulfur dioxide and other pollutants, putting wildlife and local populations at risk.
