"Trace minerals" has a range of definitions, but, with regard to nutrition, generally means minerals that are used in very small amounts in the body, mostly in enzyme reactions
Essential dietary trace minerals are those that must be obtained through the diet and/or from supplements. These include chromium, copper, fluoride, iodine, iron, manganese, molybdenum, selenium, and zinc. Other trace minerals you may see on supplement labels include boron, nickel and tin (stannous chloride).
