Gold ore is a rare mineral block found underground. Deepslate gold ore is a variant of gold ore that can generate in deepslate and tuff blobs. Gold ore drops as raw gold if mined by an iron pickaxe or higher. If mined by any other tool, it drops nothing. Mining with a Silk Touch pickaxe drops itself. It is affected by Fortune enchantment, dropping 12, 13, or 14 raw gold respectively

Gold mining is the extraction of gold resources by mining. Historically, mining gold from alluvial deposits used manual seperation processes, such as gold panning. However, with the expansion of gold mining to ores that are not on the surface, has led to more complex extraction processes such as pit mining and gold cyanidation. In the 20th and 21st centuries, most volume of mining was done by large coporations, however the
