  • 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
    • 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
