احصل على السعرThis leaves us with using the "environment" of the ore body or its "geologic setting" as perhaps the best criterion for the classification of ore bodies. 4. Classifications vary, and in general they depend on one or more of the following criteria: •Descriptive •Morphology •Commodity •Genetic •Environment
احصل على السعرIron corrodes easily, so iron artifacts from ancient times are much rarer that objects made of silver or gold. This makes it harder to trace the history of iron than the less reactive metals. Artifacts made from meteorite iron have been found dating from about 5000 BC (and so are about 7000 years old) – for example iron beads in graves in Egypt.
