Gold mine, also known as crude gold, produced in mines, gold mines, mostly with the underground hot springs gush precipitated by sewing thin plot into rock, often with quartz sandwiched in the gap in the rocks. Mine gold and other metals are mostly associated, among other metallic silver to gold, platinum, zinc and other metals not made before the other is called crude gold. Gold ore produced in different mining and other metal components contained different, so the tunnel rake slag, slag rake fineness uneven, generally between 50% -90%. Gold in the earth's crust abundance already low, and have an affinity for sulfur resistance, pro-sex rake copper slag much money, the nature of the pro-ferrous melting point and so on. To form the industrial slag deposits in the mine rake, gold enrichment thousandfold want to form a large ore-grade ore, gold will have enriched thousands, hundreds of thousands of times, or even higher. Generally believed that huge gold generally through a long geological time, through a variety of sources, tectonic evolution and mineralization superimposed times it may be forming.
