Which of the ores mentioned in Table 6.1 can be concentrated by magnetic separation method? |
| Answer» Solution :Ores which are magnetic in NATURE can be separated from the non-magnetic impurities by magnetic SEPARATION. For example, ores of iron such as haematite `(Fe_(2)O_(3))`, MAGNETITE `(Fe_(3)O_(4))`, siderite `(FeCO_(3))` and iron PYRITES `(FeS_(2))` being magnetic can be seprarated from non-magnetic impurities by magnetic separation method. | |
