moreBulldozers, drills, explosives and truck are all necessary for excavating the land. In the case of placer mining, unconsolidated gravel, or alluvium, is fed into machinery consisting of a hopper and a shaking screen or trommel, which frees thedesired mineralsfrom the waste gravel. Themineralsare the concentration using sluices or jigs.
moreUsually these surveys are very informativefor determining rocksbecause you end up with both an IP and resistivity map at the same time, allowing both measurement types to be interpreted. It is therefore important formineral exploration, as sulphideminerals– including those hosting gold, silver and copper, generate a very large IP signature.
