Iron ore isn't pure iron oxide it also contains an assortment of rocky material. This wouldn't melt at the temperature of the furnace, and would eventually clog it up. The limestone is added to convert this into slag which melts and runs to the bottom.
copper oxide ore processing equipment ball mill offers 615 copper ore specification products. About 30% of these are mineral separator, 29% are mine mill, and 19% are crusher. A wide variety of copper ore .
Lead and Zinc Lead and zinc ores are usually found together with gold and silver. A leadzinc ore may also contain lead sulfide, zinc sulfide, iron sulfide, iron carbonate, and quartz. When zinc and lead sulfides are present in profitable amounts they are regarded as ore minerals. The remaining rock and minerals are called gangue.

charge material of copper concentrate mixed with a siliceous flux (often a lowgrade copper ore) is heated in air to about 650°C (1200°F), eliminating 20 to 50 percent of the sulfur as sulfur dioxide (SO2). Portions of impurities such as antimony, arsenic, and lead are driven off, and some iron is converted to iron oxide.
