The term "ore" refers to a rock or mineral mass that contains enough of an element or compound to make it economically feasible to mine. This collection of 15 mounted specimens includes some of the more important metal ores that we mine for important industry and trade purposes. Copper ore, for instance, is mined for a variety of industrial purposes. Copper is an excellent conductor of electricity and is thus used for electrical wire.
A detailed handbook is included, which defines key terms, gives the specific gravity and hardness as well as a brief description for each ore. An excellent study tool for those with an interest in geology, or a great gift for collectors who are interested in the practical and industrial applications of rocks and minerals.
