The Amaon is considered to have great potential for mineral assets namely copper tin nickel bauxite manganese iron ore and gold. As a result governments are providing tax incentives for large-scale projects in order to boost development. As extractive technologies improve it is likely that the scale of Amaon mining will increase
2019-2-4quantity of mineral ore called the strip ratio is usually greater than one and can be much higher. For example if a proposed mining project involves the extraction of 100 million metric tons of mineral ore then the proposed mining project could generate more than one billion metric tons of overburden and waste rock
Mining and associated infrastructure developments can present themselves as economic opportunities that are difficult to forego for developing and industrialised countries alike. Almost inevitably however they lead to biodiversity loss. This trade-off can be greatest in
2020-5-19They note that global efforts have successfully helped to curb other causes of Amaon loss such as agriculture and cattle. Key minerals targeted by mining companies in the Amaon include iron ore for steelmaking and bauxite to produce aluminum. The study was conducted by researchers in the U.S. Brail and Australia
