1 Minerals, Rocks, Aggregates, Metals
Physical Resources Minerals, Rocks, Aggregates, Metals

2 Mining methods e.g large open cast
Unsustainable Methods Mining methods e.g large open cast Mining the Resources Ore processing – requires huge energy inputs and produces large volumes of waste

3 Consequences Land Disturbance Subsidence Water Pollution
Acid Mine Drainage Mining the Resources Dust and Noise Pollution Habitat Loss Larger energy inputs

4 Mining the Resources Locally- Nationally-
Methods to increase sustainability Locally- Landscaping Water sprays Baffle Mounds Timing – blasting and transporting resources in daylight hours Leachate Collection Acid Neutralisation Mining the Resources Nationally- Quotas- Reduces the extraction and over use of limited resources Internationally- Benefaction – the upgrading of a resource that was previously considered to be too costly to extract. Relieves pressure on other resources Development of new technologies e.g gravity and seismic surveys to accurately detect resources

5 Resource wastage Unnecessary use Over consumption Using the Resources
Unsustainable Methods Resource wastage Unnecessary use Using the Resources Over consumption

6 Consequences Resource depletion Using the Resources Deeper mines
Increase in cost Search for resources in new, undisturbed areas Using the Resources Deeper mines Lower grade ores

7 Using the Resources Locally- Nationally-
Methods to increase sustainability Locally- Recycling- If organised efficiently, it can reduce the demand on fresh deposits of resources. New technologies have also made it possible to recovery waste Nationally- Using the Resources Maximisation – the use of a variety of methods to avoid waste and increase production of a resource Internationally- Substitution e.g replacing lead for graphite in pencils or tungsten for LED lightbulbs Rationing- Last resort management strategy but could become a reality in future if consumption remains at the current rate e.g the Second World War
