- a comparison of two minerals in the Peak District
- limestone
- uses
- 6 million tonnes a year
- 56% road chippings
- 23% cement
- 17% chemicals
- characteristics
- heavy and bulky
- low value
- common rock in the UK
- we can use alternatives instead of it EG chalk for cement
- easy to use and prepare by mechanical crushing
- extraction
- transported by lorries
- quarrying happens with a large surface impact
- explosives used
- many large machines
- carves away hills making lots of dust and noise
- uses
- Fluorspar
- uses
- 60,000 tonnes a year
- 35% used in stell industry
- 30% in chemicals Eg solvents and toothpast
- characteristics
- light and fine
- has a very high value
- rare mineral in the UK
- there are no alternatives to use instead
- complex chemical processing is needed
- extraction
- mined with little surface impact
- explosives are used initially
- there is little waste and the waste is used to fill the mines
- lorries are needed but fewer than limestone
- little environmental impact as small scale and underground
- uses
- limestone
