Titaniferous Magnetite Deposits of the Laramie Range, Wyoming* By R A. DIEMf:R INTRODUCTION Titaniferous iron ore deposits in the Laramie Range were first reported in 1850 by Stansbury (22: 266)t. They have since been found at a number of localities in the form of dike-like bodies in an area of

Ore size does affect direct reduction of titaniferous ...

This work tested whether ore particle size affects the carbon-basedpre-reduction of titaniferous magnetite. Pre-reduction is performedat a temperature of some 1100°C in a rotary kiln, in the HighveldSteel process. Laboratory isothermal reduction measurements wereperformed with ore-coal mixtures at this temperature, to test theeffect of ore particle size. The results show that size does limit thedegree of reduction

Up to10%cash back  To improve the reducibility of titaniferous magnetite ore (TMO), a technique of high-temperature heating followed by water quenching has been adapted. This quenching technique imparts cracks into the dense TMO which in turn leads to the enhancement of reducibility during carbothermal reduction using boiler grade coal. A major problem associated with TMO is that the reducibility of the ore

titaniferous magnetite from the crude Choteau ore. Pig irons containing less than 0.05 percent phosphorus or sulfur were readily produced from the titaniferous materials; iron recoveries ranged from 92 to 98 percent. The Choteau ore was ground to minus 65-mesh to produce a concentrate containing 60 percent or more iron. The steel produced from the

Magnetite - Wikipedia

Magnetite is a mineral and one of the main iron ores, with the chemical formula Fe 3 O 4.It is one of the oxides of iron, and is ferrimagnetic; it is attracted to a magnet and can be magnetized to become a permanent magnet itself. It is the most magnetic of all the naturally occurring minerals on Earth. Naturally magnetized pieces of magnetite, called lodestone, will attract small pieces of ...

Robertson (1956) estimates the pyroxenite to contain from 5% to 51% magnetite and ilmenite. He also noted that the greatest concentration of titaniferous magnetite occurs in the lower portions of the pyroxenite. Taylor and Noble (1969), however, report a relatively uniform titaniferous magnetite content of 15 to 20% for the pyroxenite.
