Environmental Risks of Mining

Open pit mining, where material is excavated from an open pit, is one of the most common forms of mining for strategic minerals. This type of mining is particularly damaging to the environment because strategic minerals are often only available in small concentrations, which increases the amount of ore needed to be mined.

Lecture 4: Mining waste

Iron ores generally have higher grades than sulphide or gold ores, often going over 50 per cent or more. Less tailings are therefore generally produced in iron ore projects. After separating the valuable minerals, the tailings are often pumped in a slurry through pipes to be deposited in a tailings storage facility (TSF) (also called tailings management facility, TMF).

How is Iron Refined from Ore? (with pictures)

To purify and strengthen iron, materials like coke are mixed in with it to remove oxygen. To coax the oxygen atoms away from the ore requires heat and an alternate atomic partner for the oxygen to bond to.Carbon fills this role nicely, and is readily available in the form of everyday charcoal, or coke, a form of carbon made from coal.

Different Types of Iron Ore

 · 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 concentration.
