The environmental impact of aluminium Reynaers

2021-10-31  The ore bauxite contains aluminium oxide. It is available in various tropical and subtropical regions. By surface mining, it is removed from the ground surface. Next step in the production of aluminium is to obtain the aluminium oxide out of the bauxite. Melting the aluminium oxide will release pure aluminium, which will be casted into ingots.

Toxicity, mechanism and health effects of some heavy metals

2014-11-15  Aluminium showed adverse effects on the nervous system and resulted in loss of memory, problems with balance and loss of co-ordination (Krewski et al., 2009). People suffering from kidney diseases find it difficult to eliminate aluminium from the body, resulting in aluminium accumulation in the body leading to bone and brain damage.

Environmental effects of aluminium SpringerLink

Aluminium (Al), when present in high concentrations, has for long been recognised as a toxic agent to aquatic freshwater organisms,i.e. downstream industrial point sources of Al-rich process water. Today the environmental effects of aluminium are mainly a result of acidic precipitation; acidification of catchments leads to increased Al- concentrations in soil solution and freshwaters. Large

Causes, Effects and Solutions for Mining E&C

There are also some adverse effects of mining on aquatic life. Since many harmful by-products of mining often reach water bodies due to inappropriate disposal by mining companies, all kinds of water animals will suffer from toxic compounds. This may include the contamination of fishes with heavy materials or even radioactive substances.
