Different Types of Iron Ore
The per cent of iron in the ore as mined must be not less than 50%, if it is to be used without being first improved (beneficiated) by cobbing, washing, calcining, or magnetic concentration. Leaner ore is found in very large quantities; and in a favorable situation, it may be workable by some concentrating process.

Processing High-Grade Concentrates from Challenging Low-Grade Iron Ore
On an average global basis, iron ores tend to decrease in Fe grade over time. With the exception for some deposits that are logistically challenged, iron ore resources in more accessible areas may often have processing issues, especially if high-grade concentrates are desired. This paper addresses some of these with examples on how technological …

Iron
Commodity Iron is a brittle, steel gray to silvery gray metal used through millennia. Advent of its use was so significant that the Iron Age of human prehistory is named for the dominant use of the metal. Iron has had numerous names throughout human history. Our current name for the metal is likely from Middle English and was itself derived from Proto-Germanic …
