Life cycle assessment Life cycle assessment (LCA) is a technique used to assess the environmental impact associated with all the stages of a product's life from the extraction of raw materials through to processing manufacturing distribution and end-of-life treatment Gold mining is a global business with operations on every continent except Antarctica and gold is extracted from mines of widely varying types and scale Mines and gold mining operations have become increasingly geographically diverse far removed from the concentrated supply of four decades or so ago when the vast majority of the world's gold came from South Africa

1 Exploration EXPLORING FOR GOLD IS A COMPLEX SCIENTIFIC AND TIME-CONSUMING PROCESS With odds of only one in 3 000 discoveries leading to mine development and only 10 percent of the world's gold deposits containing enough gold to mine exploration can be labor-intensive time consuming and expensive

Much of the company's coal production was sold to the adjacent Morupule Power Station (MPS) of Botswana Power Corp (BPC) Record coal sales in 2005 were 967 242 t which was an 8% increase compared with the total in 2004 A coal washing plant was under construction

Coal impacts: water pollution When you burn charcoal in your grill at home ash is leftover The same is true for coal-fired power plants which produce more than 100 million tons of coal ash every year More than half of that waste ends up in ponds lakes landfills and other sites where over time it can contaminate waterways and drinking water supplies

Impact of oil spills Spilt oil can pollute streams rivers and if it soaks through the soil and rock groundwater In the UK our drinking water supplies come from rivers and groundwater We must protect them both from pollution Oil is toxic and harmful to plants and animals and a threat to their habitats Environmental impact of oil
