    Gold Mining and Processing: Everything you Need to

    The Basics of Gold Mining and ProcessingWhat Is Gold Used for?Where Is Gold Found?The Gold Mining ProcessPlacer deposits, such as streambeds where people can pan for gold, are not the typical locations used by commercial gold mining companies. The process begins when geologists take ore samples to determine the best places for companies to mine. Once mining engineers know where gold is located and what other materials surround it, the mining process can begin. If the gold is located close to the surface, it’s mined with ope在generalkinematics上查看更多信息发布日期: 2014-8-15

    Mineral Exploration: A Short Guide to Understanding

    Beginning Exploration ActivitiesBuilding RelationshipsData Accumulation and AnalysisMineral explorers (also called Prospectors) often use planes or helicopters to view large areas efficiently. Aeromagnetic surveys, satellite photos, air photos and detailed maps help prospectors identify mineralization. Sometimes, (as is often the case in Canada) Federal and Provincial governments will conduct basic exploration activity such as aeromagnetic surveys to provide potential prospectors with information. This provides the prospectors an incentive to view the data and consider the possibility of s
