2022.3.9 The laterization process further means that bauxite deposits tend to be shallow and scattered, as they are in the Vietnamese Central Highlands. As a result, more than 80% of world bauxite production is extracted through open-pit mining, also known as strip mining or surface mining (Gow Lozej, 1993; ...

The open pit method is often the easiest and the most inexpensive form of mining. Bauxite mining, which commenced in 1916 in Linden, Guyana, has left many abandoned pits upon closure of mining activities; subsequently pit lakes have been formed. Globally, Acid Mine Drainage (AMD) is a common water quality problem for pit lakes.

2010.2.1 The embodied energy values were 153 MJ/t ore, 55 MJ/t ore and 8329 MJ/t concentrate for iron ore, bauxite and copper concentrate respectively. These results show that loading and hauling made the largest contributions (approximately 50%) to the total greenhouse gas emissions for the mining and processing of iron ore and bauxite.

2014.6.1 Abstract. Kaolin is used in many consumer products and as a functional additive and process enabler in manufacturing. It is typically extracted from open-pit mines that range from small to very large scale (tens to hundreds of thousands of dry metric tons produced per year). Ore processing consists of removing impurities, engineering particle ...

Recently, bauxite mining in Kuantan, in the state of Pahang, stained fifteen kilometers of Pahang’s coastline with red arsenic particles and heavy metal pollution washed from open-pit bauxite mines into the nearby sea. This has caused potentially catastrophic damages to the ecosystem off the coast of Pahang.

Surface mining is more common than underground mining because most of the bauxite deposits occur near the surface. The extraction of bauxite takes place by shallow, open-cut mining following the open-pit method. The bauxite ores content is of different types and the most amount of clay, and need to be washed before the process (Donoghue et al ...
