Ashish Deoar: Ashish Deora : what types of Iron Ore
In the late nineteenth and mid twentieth hundreds of years, iron mineral was of such top notch that taconite was viewed as an uneconomic waste item. After World War II, the vast majority of the high review metal in the United States had been mined out, thus taconite was swung to as another wellspring of iron. To process taconite, the metal is ...

Grain size distribution and composition of modern dune and ...
Grain size distribution and heavy mineral content of beach and dune sediments from the Malindi Bay coast, Kenya were determined. Grain sizes were determined by dry sieving sediments; samples represent the upper 5 mm of surficial sediment, collected from the four main geomorphological units (beach, berm zone, foredune and dunefield), during three observation periods, covering the southeast .

This coarser grain size requires only 10 percent of the energy needed to liberate the iron compared to the finergrain size of taconite ore loed in the northern portion of the trough. Additionally, the coarser the ore is, the softer it is and the faster it goes through the autogenous grinding mill that grinds and liberates the iron.

History of Minnesota's Lake Superior
In 1965, processed taconite constituted onefourth of the iron ore consumed in the United States and Canada. It soon became impractical to mine or ship the older highgrade ore, because the taconite proved so economical and so uniform. In 1967, taconite shipments surpassed those of natural ores.
