Mining’s Impacts on Forests | Chatham House

While mining is not always a primary direct driver of deforestation and forest degradation, its indirect and cumulative forest impacts can be significant. Up to one-third of the world’s forests may already be affected by mining, with regions such as the Amazon, the Congo Basin and Southeast Asia at particular risk. Given the anticipated demand for minerals such as iron ore, copper, gold

Timber trade restrictions and tropical deforestation: a

01/04/2001· Timber trade restrictions have been proposed as a means to reducing tropical deforestation. This paper analyses the consequences of such trade interventions, emphasising the effects on logging behaviour and the allocation of land between forestry and alternative activities (e.g. agriculture). Tropical forestry is modelled as the mining of a heterogeneous, non-renewable resource.

Some affect of mining on the environment and land

Effect on Land Deforestation: Mining requires large areas of land to be cleared so that the earth could be dug into by the miners. For this reason, large-scale deforestation is required to be carried out in the areas where mining has to be done. Besides clearing the mining area, vegetation in the adjoining areas also needs to be cut in order to construct roads and residential facilities for

A mill cut-off grade is a level set that is considered to be the lowest quality of already mined ore that is economically feasible to continue processing. Different materials have different properties that determine a feasible cut-off grade. Often these grades are set at over-conservative levels. The easiest way to improve efficiency in mining and to decrease waste products is to decrease a
