Quartz And Limestone And Gold

A cubic centimeter each of quartz olivine and native gold weighs 2.5 3.0 and 19.8 grams respectively. these weights indicate that a olivine melts at a higher temperature than either gold or quartz b gold has a higher density and specific gravity than quartz and olivine c gold is 6 to 7 times harder than olivine and quartz.

    A good place to look for gold-bearing quartz rocks is to go where other miners and prospectors have already been. even rocks that have been passed over by other prospectors as well as gold mine tailings leftovers may contain gold. fortunes have been made by patiently and systematically reworking the leftovers and tailings of fly-by-night and slash-and-grab gold prospectors and miners. large corporate efforts to extract gold often leave behind gold that is more efficiently and cost-effectively extracted by small-time miners and weekend prospectors.

  • Gold quartz in limestone mining solution

    Look for gold in quartz veins in areas where the bedrock is fractured by tectonic and volcanic activity. fractures and cracks in the bedrock form ideal pathways for superheated water and steam under pressure to flow and to precipitate out their dissolved mineral and heavy metal loads. gold is deposited by precipitation along the fracture edges and walls. active geyser basins and old extinct geysers are evidence of such hydrothermal activity.

    The solubility of sio2 is almost 0 at at 1 bar and 25 c, but increases strongly with pressure and temperature. for example, at 200 c and 2000 bar 2 kbar, 0.2 gpa, about 56 km depth, conditions that are reasonable for an unmetamorphosed but deeply buried limestone, you can fit about 500 mg of sio2 in 1 kg of h2o. at atmospheric pressure thats one litre of water, but its much less voluminous at depth. that is a lot of sio2 once the fluid goes up towards the surface, it depressurises and cools, causing precipitation of quartz.
