Different Types of Iron Ore -

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 . The metal concentration in the ore bodies can be tens of % for some metals e.g. iron down to parts per

Acid formation in these buried deposits occurs at a slow and usually harmless rate. Extracting the valuable metals from these rocks however involves extracting and crushing the ore. This makes the ore more “chemically available” for acid-forming reactions.
