Mar 24, 2017 In some instances there may be enough variation in the specific gravity of different grades of ore to require different factors for each. Thus, in the Lake Superior iron-ore districts curves have been constructed showing the variation in cubic feet per ton with variations in iron content. One of these is shown in figure 11, A.
wash ore, clay ore, rock ore and pipe ore lie concealed under the surface soil of the fields. Passing to the south side of the Harrisburg and Potomac Railroad the geologist finds himself on a belt of country of a different kind, full of deposits of brown hematite iron ore, belonging to another and older series.
iron ores account for a high proportion of Chinas iron ore resources, while the total reserves of typical hard-to-use iron ore resources such as siderite, limonite, and fine-grained ore are more than 20 billion tons 21 . As Fig. 2 shows, these resources are widely distributed in Liaoning, Gansu, Shaanxi, and Sichuan provinces, etc 22 .
Marandoo iron ore mine is situated 35km east of Tom Price in the province of Pilbara, in Western Australia. It is 100 owned and operated by Hamersley Iron, a wholly owned subsidiary of Rio Tinto Iron Ore.
