As a rule, a mine produces concentrates. In rare cases it mines rich ores which can be shipped directly. In some cases price quotations for concentrates and ores are available, i. e. iron ore, tungsten, and antimony concentrates or "yellow cake" 3, U 3 O 8, the end product of uranium mines. These quotations are supplied by the price lists of the weekly "Metal Bulletin" or the "Engineering and Mining Journal".
