The invention discloses a method for smelting ash iron by using a cupola furnace, and belongs to reduction of iron ore and manganese ore. The raw materials comprise the following materials in percentage by mass: 0-70 percent of iron ore powder, 0-60 percent of manganese ore powder, 0-10 percent of silicon carbide, 5-15 percent of reducing agent, 0-10 percent of limestone powder, 5-15 …
The raw materials were fly ash, low grade bauxite and a small quantity of clay. The chemical compositions of raw materials are shown in Table 1.It can be seen from Table 1 that the content of SiO 2 in fly ash is much higher than the content of Al 2 O 3, and the contents of impurities including Fe 2 O 3, TiO 2, CaO and MgO, especially the content of K 2 O and Na 2 O are relatively higher than ...

Efforts to generate organomanganese reagents under ball-milling conditions have led to the serendipitous discovery that manganese metal can mediate the reductive dimerization of arylidene malonates. The newly uncovered process has been optimized and its mechanism explored using CV measurements, radical trapping experiments, EPR spectroscopy ...
