巴依可夫冶金研究所与可燃矿物研究所合作,在莫斯科炼焦煤气工厂进行了在两段旋涡室系统中磁化焙烧土坎矿床铁矿石及在两段旋涡室系统中净化废气的工作。用克拉斯诺亚尔斯克边区伊尔沙-博罗迪诺矿床的褐煤作为还原剂,褐煤粒度0—1毫米。褐煤的工业分析如下:水分18%,挥发分47.1%,灰分5.4%,硫0.25%。上坎矿床是集加津诺科马罗夫斯克地区(巴什基尔矿群)铁矿矿床中最大的矿床。它是别洛列茨克冶金联合企业的主要原料基地。该矿床的矿石基本上是褐铁矿。分布最广泛的是两种矿石类型:赭色粉状矿和块状矿。矿石中平均含Fe41.7%,SiO_220%,Al_2O_33.6%,Mn1%。选矿工艺试验确定,土坎矿石只需要还原焙烧,然后磁选。
In cooperation with the Institute for Combustible Minerals, the Bakoyev Metallurgical Institute carried out the work of magnetizing and roasting ores in the two-stage vortex chamber system and purifying exhaust gas in two-stage vortex chamber system at the Moscow Coking Gas Plant. Using lignite from the Ilsa-Borodino deposit in the Krasnoyarsk border region as the reducing agent, the lignite size is 0-1 mm. The industrial analysis of lignite is as follows: moisture 18%, volatile 47.1%, ash 5.4%, sulfur 0.25%. The Shangkang deposit is the largest deposit in the iron ore deposit of the Gadunokomarovsk region (Bashkirchem Group). It is the main raw material base for the Beloretsk metallurgical complex. The ore of the deposit is basically limonite. The most widely distributed are the two ore types: ocher powder and lump ore. The average ore contains 41.7% Fe, 20% SiO 2, 33.6% Al 2 O 3 and 1% Mn. Beneficiation process test to determine, ridge ore only need to restore roasting, and then magnetic separation.
