    Quartzite. Quartzite is a metamorphic rock derived from sandstone that is distinguished from sandstone by its fracture. Sandstone breaks along grain boundaries, whereas quartzite is so well indurated (hardened) that it breaks across constituent grains.

  • How Is Quartz Extracted? Sciencing

    The reason for this is that although quartz is known for its hardness, it damages easily if it is suddenly exposed to a change in temperature, such as that caused by a blast. Instead, mining operations use bulldozers and backhoes to remove soil and clay, and expose the quartz crystal veins in the rock.

  • Quartzite Wikipedia
    OverviewOccurrenceUsesSafetyEtymologySee alsoExternal links

    Quartzite is a hard, non-foliated metamorphic rock which was originally pure quartz sandstone. Sandstone is converted into quartzite through heating and pressure usually related to tectonic compression within orogenic belts. Pure quartzite is usually white to grey, though quartzites often occur in various shades of pink and red due to varying amounts of iron oxide (Fe2O3). Other colors, such as yellow, green, blue and orange, are due to other minerals.

  • How to Find Gold in Quartz Sciencing
    GeologyFeaturesPreparationGenerally, gold originates upstream from places where it is actively panned or has been historically panned and sluiced from sand and gravel deposits. Look for gold and gold-containing quartz rocks in areas where volcanic hydrothermal activity has taken place in the geologic past. These areas include the regions around old gold mines and rock outcrops upstream from placer gold deposits where gold has eroded out of its bedrock, See more on sciencing
