[PDF] Mining, Pollution and Agricultural Productivity: Evidence
01/09/2012Most modern mines in the developing world are located in rural areas, where agriculture is the main source of livelihood. This creates the potential of negative spillovers to farmers through competition for key inputs (such as land) and environmental pollution. To explore this issue, we examine the case of gold mining in Ghana.

How Gold Is Mined
Processing gold involves transforming rock and ore into a metallic alloy of substantial purity – known as dor – typically containing between 60-90% gold. During its life, a number of factors – such as the price of gold or input costs – will affect which areas of an ore body are deemed profitable (economic) to mine.
