INTRODUCTION TO MINING MINING'S CONTRIBUTION TO CIVILIZATION Mining may well have been the second of humankind's earliest endeavors— granted that agriculture was the ﬁrst. The two industries ranked together as the primary or basic industries of early civilization. Little has changed in the
The business of mining iron ore is a high volume, low margin industry because of the low value of iron. The transport of iron ore by way of railway or freight requires a highly stable infrastructure for the mining production to be economically feasible. As a result, the mining of iron ore has remained in the control of a few major companies.
Before mining can commence the land needs to be cleared of timber and vegetation. Alongside this process may be the collection of seeds and/or saplings, for inclusion in a seedbank, which will form the basis of postmining revegetation of the site. Next the top soil is removed and is usually also stored for replacement during rehabilitation.
Hematite is the most important iron ore. The iron content of the pure minerals is as follows: Ankerite is a carbonate of lime, magnesia, manganese, and iron. It is of valuable composition, carries only 14 or 15% of iron, and is used more for its lime and magnesia as a flux than for its ironcontent.
