Due to the alluvial gold the output of this metal in the Urals grew up to 8.2t in 1870, 9.8t in 1880 and reached its peak in 1892 - 12.8t. Later with depletion of the richest placers it began to decline and in 1913 made up 8.2t. Many famous nuggets were found in the alluvial deposits of the Urals in the XIX century.
Estimates for average water consumption at a mine site vary considerably based on the processing method applied (e.g., heap leaching, flotation, gravity), but a global summary for water withdrawals for gold mines found the 'average' gold mine used ~0.350 m3/metric ton of ore-grade rock (Gunson, 2013).
The IGR 3000 Gold Washplant was designed for a nominal 30 tons/hour feed rate based on an alluvial type material with moderate clay contamination. Material is loaded into the plant feed hopper through a static scalping grizzly with 75 mm bar spacing. Oversize is to be periodically removed manually from the grizzly. Undersize feed material is washed into the scrubber feed chute by water jets ...

Total Victorian alluvial gold production is estimated to be about 1500 tonnes but historical records are poor or non-existent, so there is uncertainty about this number. The largest alluvial goldfields extended over distances of around 10 kilometres and produced more than 100 tonnes of gold.
A new metric has since been developed by the World Gold Council to report the "all-in sustaining costs" of mining gold. These numbers report that the cost of extracting an ounce of gold is actually over $1,000 per ounce, well above the aforementioned numbers. And since gold is currently trading at just over $1,200 per ounce, it explains why ...

What is Gold? Native gold is an element and a mineral. It is highly prized by people because of its attractive color, its rarity, resistance to tarnish, and its many special properties - some of which are unique to gold. No other element has more uses than gold.
Many of the earliest alluvial mines were extremely rich (10's or even 100's of grams of gold per tonne of gravel), but most gravels had at most a few grams of gold per tonne. A wide variety of techniques have been tried over time, but all techniques focus on water-washing of the gold-bearing gravel in some way.
A one troy ounce Gold nugget is rarer to find than a five-carat Diamond. One cubic foot of Gold weighs half a ton. Gold is chemically inactive and is not affected by air, heat or moisture. There are more than 400 references to Gold in the King James Bible. It is estimated that 142,000 tons of Gold have been mined throughout history.

The average content of Au (gold) elements in the earth's crust is <0.01ppm (that is, <0.00001‰), and the content is very very small. Through a series of mineralization activities such as magmatism and crustal movement, gold is enriched to 1 gram per ton, that is, one gram of gold per ton of ore, ie 0.001 ‰.

The answer would be a fraction or a decimal of a ton since a ton is more than an ounce. A lot more. If you wanted to know how many ounces were in a ton, that would be easier. There is 2000 pounds in a ton. (US). There are 16 ounces in a pound. If you multiply 16 times 2,000 that will tell us how many ounces are in a ton. 16 X 2,000 = 32,000.
1.8 metric ton per meter of gravel is about right,with a 6+4 trailer holding half a meter max is at its back breaking limit. I was wondering how many realise how much 3 to 4 meters is!
