Mining of Iron Ores IspatGuru

To gain access to the iron ore deposit within an area, it is often necessary to mine through or remove waste material (also known as overburden) which is not of an interest. The total movement of ore and waste constitutes the mining process. Often more waste than ore is mined during the life of a mine, depending on the nature and location of the ore deposit. Removal and placement of overburden is a major cost in the mining

product of mineral extraction in underground mines. The quantity and composition of waste rock varies greatly from site to site, but these wastes essentially contain the minerals associated with both the ore and host rock. The ratio of overburden excavated to the amount of mineral removed is called the overburden ratio or stripping ratio. For example a stripping ratio of 4:1 means that 4 tonnes of waste rock

Reuse of iron ore mineral wastes in civil engineering

01/09/2008 The iron ore is predominantly mined by opencast mining throughout the country. The solid material generated in large quantities by iron ore extraction is the material that overlies the ore body and the processed tailings . These wastes contain minerals associated with the ore body and host rock, mainly the laterite, and sometimes the clays. Mine waste generally has different physical and

Management of Overburden Storage Areas at the Mt

Development of the Mt. Whaleback mine commenced in 1968. The mine currently produces approximately 18 million wet tonnes of saleable product and 53 million tonnes of waste material annually. Ultimately, some 3.3 billion tonnes of waste rock will be mined and located into overburden storage areas (OSAs) in and around the final pit.

Lecture 4: Mining waste SGU

Waste rock is the rock that is excavated to reach the ore. The amount of waste rock that needs to be removed depends on the geometry and location of the ore body, along with the mining method used and the composition and stability of the rocks. The ratio between waste rock and ore production is called the stripping ratio. For example, a stripping ratio of 2:1 means that 2 tonnes of waste rock

Mining Waste an overview ScienceDirect Topics

Overburden is an important type of mine waste. Overburden includes the soil and rock that is removed to gain access to ore deposits at open cast mines. It is usually piled on the surface at mine sites where it will not impede further expansion of the mining operation, because moving large volumes of

There is virtually no waste rock data reported for nickel, lead-zinc-silver, iron ore or bauxite mining, with only a small number of waste:ore ratios available for some years and not the historical record of such data. There is only limited and recent data available for overburden in coal mining, but due to

Sustainable use of mine waste and tailings with suitable

Open- cast mining involves removal of complete waste rock to expose the ore body or coal. The process of removing the waste bound to damage the natural ecosystem by producing various types of pollution like land degradation, air pollution, dust pollution etc. The waste produced is generally dumped outside the mine in the form of overburden dumps.
