Pure magnetite contains 72.4 percent iron, hematite 69.9 percent, limonite 59.8 percent, and siderite 48.2 percent, but, since these minerals never occur alone, the metal content of real ores is lower. Deposits with less than 30 percent iron are commercially unattractive, and, although some ores contain as much as 66 percent iron, there are ...

The process in­cludes three stages: first alu­minum ox­ide is ob­tained from nephelines or baux­ites, then in­dus­tri­al alu­minum is ex­tract­ed from it, with a lev­el of pu­ri­ty of 99.5%. This is in­suf­fi­cient for some in­dus­tri­al pur­pos­es, so in the last stage the met­al is pu­ri­fied to 99.99%.
