Indicator mineral methods in mineral exploration

exploration targets. Another major advantage of indicator mineral methods is that grain morphology, surface textures or mineral chemistry may be examined to obtain information about transport distance and bedrock source. Indicator minerals have become an important exploration method in the past 20 years and now include suites

3 Technologies in Exploration, Mining, and Processing ...

Currently, almost all nonmetallic minerals (more than 95 percent), most metallic ores (more than 90 percent), and a large fraction of coal (more than 60 percent) are mined by surface methods (Hartman, 1987). However, as surface mineral deposits are exhausted, …

Geophysical Methods in Mineral Exploration

Surface geophysical surveys have been applied to mineral and petroleum exploration for many years. A magnetic compass was used in Sweden in the mid-1600s to find iron ore deposits. The lateral extent of the Comstock ore body was mapped using self-potential methods in the 1880s. A very crude type of seismic survey measured the energy resulting ...

Basic Gold Prospecting & Exploration Methods

Feb 29, 2016· Seismic Method. Surface seismic techniques used in gold exploration are restricted to seismic refraction and seismic reflection methods. Probably, the first one is the most employed. The equipment employed for both techniques is very similar and assure the travel time of acoustic waves propagating through the subsurface.

Exploration: Finding minerals | Mining of mineral ...

Exploration methods are used to find, and assess the quality of mineral deposits, prior to mining. Generally a number of explorative techniques are used, and the results are then compared to see if a location seems suitable for mining.

3D Seismic Exploration for Mineral Deposits in Hardrock ...

To apply these same methods to mineral exploration in hardrock environments we need to adapt the time-tested seismic techniques developed for oil and gas exploration to the problems associated with a seismically reflective medium. In Canada, 3D seismic investigations focus on massive sulfide deposits, rich in copper, nickel and zinc.
