Gold mining - Wikipedia

Gold mining is the extraction of gold by mining. World gold production was 3,612 tons in 2022. Historically, mining gold from alluvial deposits used manual separation processes, such as gold panning. The expansion of gold mining to ores that are not on the surface, has led to more complex extraction processes such as pit

Gold Price Chart

The gold/silver ratio is simply the amount of silver required to buy a single ounce of gold. For example, if gold is at $1200 per ounce and silver is at $15 per ounce, the ratio would be calculated as $1200/$15 = 80. This means it would take 80 ounces of silver to buy a single ounce of gold. Charts of this ratio may potentially be useful, as ...
