   What are the different types of gold ores?

   • In addition to gold, such ores include copper, lead, zinc, tungsten, and antimony. This gold ore contains large sulfides (10%–20%). In addition to pyrite, natural gold is closely related to minerals such as copper and lead. The grain size of native gold is relatively coarse, but the grain size varies widely and unevenly with the mining depth.

   6 days ago · Gold mining is the extraction of gold by mining. 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 mining and gold cyanidation.
