Different Types of Iron Ore - 911metallurgist.com
Iron Ore Formation Iron formation consists of iron ore such as siderite magnetite and hematite with silica in the form of chert jasper etc. generally in bands but sometimes not distinctly so. The bands of iron ore are at times high-grade but are often mixed with a good deal of silica the whole making an ore too lean for use without

They are found in ore bodies that can be formed in different ways for example through hydrothermal magmatic metamorphic sedimentary and precipitation processes Brown 2014; McKibben 2005; Mungall 2005; Ramanaidou and Wells 2014 .

Iron ore mining can be broadly divided into two egories namely 1 manual mining which is employed in small mines and 2 mechanized mining is suitable for large iron ore mines. Manual mining method is normally limited to float ores and small mines. Mining of reef ore is also being done manually on a small scale. The float ore area is dug up
