Not All Iron Is Magnetic (Magnetic Elements)

03/07/2019· Iron and other transition metals have partially-filled electrons shells, so some of these elements and their compounds are magnetic. In atoms of magnetic elements nearly all of the dipoles align below a special temperature called the Curie point. For iron, the Curie point occurs at 770 °C. Below this temperature, iron is ferromagnetic (strongly attracted to a magnet), but above it the iron

Different Types of Iron Ore 911metallurgist

Impurities in Iron Ores. There are certain impurities that lower the value of iron ores or may even make them valueless. Sulphur in the ore goes partly into the iron and steel and makes them brittle. While it is possible by roasting the ore and by other means to remove the sulphur, the presence of any considerable amount is objectionable. Phosphorus in steel makes it brittle. For steel-making

Gold Ore Roasting Techniques

The roasting of straight pyritic ores involves the conversion of the iron sulphides to the oxide under oxidizing conditions with the evolution of sulphur dioxide and, to some extent by catalytic action, sulphur trioxide gas also. In this chemical change the iron mineral is rendered more or less porous, thereby permitting the dissolution of the contained gold by subsequent cyanidation. Though
