  • How Gold Is Mined | Gold Mining Process | World Gold Council

    2 天前· Yet mining the ore is just one stage in a long and complex gold mining process Long before any gold can be extracted, significant exploration and development needs to take place, both to determine, as accurately as possible, the size of the deposit as well as how to extract and process the ore efficiently, safely and responsibly On average, it takes between 1020 yearsFrom the discovery of buried minerals to reclaiming land after closure of a mine, our operations can sometimes span 30 years or even longer This means we may conduct business in or near a community for decades, and even generations Throughout that time, Newmont's core values – safety, integrity, sustainability, responsibility and inclusion – give guidance to the actions of ourNewmont Corporation About Us About Mining Lifecycle
