How much iron ore is needed to produce one tone of steel?

The percentage of iron in ore varies. Back in the day, it was on the order of 2/3rds of the ore by weight. Now 1/4th by weight is more like it. Recovery rates vary, too, but your're looking at something between 2 1/2 and 3 tonnes of ore per ton of steel.

How much did the largest gold nugget from Australia weight?

The world's largest gold nugget was found in Australia in 1869. This was the "Welcome Stranger", and it measured 61cm by 31cm. It was discovered by prospectors John Deason and Richard Oates at Moliagul, which is about halfway between Maryborough and St Arnaud in western Victoria.

How do you obtain gold?

By mining it from the earth.

Gold is found in ores made up of rock with very small or microscopic particles of gold. This gold ore is often found together with quartz or sulfide minerals, these are called "lode" deposits. Native gold is also found in the form of free flakes, grains or larger nuggets that have been eroded from rocks and end up in alluvial deposits (called placer deposits). Such free gold is always richer at the surface of gold-bearing veins owing to the oxidation of accompanying minerals followed by weathering, and washing of the dust into streams and rivers, where it collects and can be welded by water action to form nuggets.

Gold extraction from ore grades as little as 0.5 g/1000 kg (0.5 parts per million, ppm) can be economical. Typical ore grades in open-pit mines are 1-5 g/1000 kg (1-5 ppm); ore grades in underground or hard rock mines are usually at least 3 g/1000 kg (3 ppm). Because ore grades of 30 g/1000 kg (30 ppm) are usually needed before gold is visible to the naked eye, in most gold mines the gold is invisible.

In all of history, only 161,000 tons of gold have been mined, barely enough to fill two Olympic-size swimming pools.

Why would people want to build a quarry near their house?

They can bring economy to the area and make employment which would also be good. They can earn lots of money from it: they could make concrete out of it build with it or use it to make products like toothpaste :D. The lime stone can also reduce acidity in lakes (I don't know why someone would want that personally) and reduce the sulfur dioxide released from coal fire power stations. I suppose they could all help if the people don't mind the eye sore of having it near and the dust and noise. Hope this helped. :)
