Primary Industry Example Definition GCSE Geography

Primary industries within the geographical context relate to the extraction of raw materials from the sea or land. Some examples relate to fishing, forestry, agriculture, mining or oil. The extraction of these core materials plays a key role to reach overall sustainability. It also ensures the survival of humankind through the use of these different resources.

Recycling the Future of Mining The Business of Mining

15/04/2012  However, mining is not the only supplier of these raw materials. Next to the primary mining industry a secondary mining industry is growing: ‘urban mining’. The existing stock of materials in the urban environment is recycled more and more. 38% of iron input in the steel making process comes from scrap. The average ‘new’ copper cable contains some 30% recycled material. The more
