蒂尔登选矿厂在美国密执安州的马克特矿区,属蒂尔登矿业公司。该矿的推算矿石储量为11亿吨。选厂的第1期工程于1974年12月投产,计6个系列,设计的生产能力为年处理原矿1,053万吨。该选厂处理的矿石为微细粒嵌布的红铁矿,矿石中的铁矿物主要是假象赤铁矿,其次为赤铁矿,还有少量的土状赤铁矿、针铁矿和磁铁矿。脉石主要是燧石。氧化铁矿物的粒度从小于1微米到100微米,一般平均为10和25微米。矿石为条带状结构。矿石平均含铁38%
Tilden concentrator in the United States, Michigan State Markt mining area, a Tilden mining company. The mine’s estimated ore reserves of 1.1 billion tons. The first phase of the plant was put into operation in December 1974 with a total of 6 series. The designed production capacity is 10,530,000 tons of raw ore per year. The ore beneficiated by the plant is finely grained red iron ore, the iron minerals in the ore are predominantly hematite, followed by hematite, and a small amount of earthy hematite, goethite and magnetite iron ore. Gangue is mainly flint. Iron oxide minerals have particle sizes from less than 1 micron to 100 microns, typically averaging 10 and 25 microns. Ores for the strip structure. Ore average iron 38%
