How to be a gold

Scientists believe that the gold deposition of gases and liquids rising from the bottom surface of the earth.

These gases and liquids to rise in the direction of the surface through cracks in the earth's crust. There is gold in abundance in the rock-forming of the crust.

And often found with metallic copper and lead. Often confused researchers for the first gold of the ore which they found a Alberait, a compound consisting of iron and sulfur. And gold; it like gold, but of little value, where it was gold, stupid. It is rare to find a piece of gold large enough to see it, although the large rocks of gold had been found in Australia in the late nineteenth century.

There is gold in the veins of metal, and in alluvial deposits or as an element in copper porphyry as well as in sea water.

Stockwork deposits. Are the veins in the earth's crust. Alluvial sediments or sand. The large particles, called nuggets or grains of gold, are found in river beds.

These particles washed away by surface water or flood water and its campaign away from the race metal. And some fragments too large.

The largest fragments found so far is O hello stranger, which is found in Molijul Victoria, Australia, in 1869, which concluded, including 6992 kilograms of pure gold.

Before that, eleven years old, I discovered a cluster Gold in Ballarat Victoria, Australia, and from which he drew 68.72 kg of pure gold.

The largest recorded cluster globally containing gold, were found in May End in New South Wales, Australia in 1872, a piece of slate and gold as high as 145 cm and 38 cm wide and weigh over 235 kilograms of pure gold.

But did not record a block real gold, because it was a mixture of slate and gold.

The alluvial deposits are of two types of fragmented, mud, and there I kind of close to the veins of gold, while the second is away from her, often in river beds.

Some gold is found in large deposits of copper deposits called porphyry copper. Gold in sea water. All sea water containing gold solution.

The result of sea water 72 mg of gold per metric ton. And scientists looking for ways to profitably mined.

It is rare for the presence of gold in pure form, but is often accompanied by silver in the natural alloy called electrum, and is usually coupled with quartz or calcite, or lead, or tellurium or zinc or copper, often mined as a byproduct of these metals.

For example, only 40% of gold extracted in the United States, is extracted from the sites may be true to name the gold mine it.
