Mining and Refining – Process World Aluminium
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.
ABB process control and automation solutions for mines ...
These days, it's recognized that mines and minerals processing plants need integrated process control systems that can improve plantwide efficiency and productivity. No matter how important the electrical side is, it's still just another factor in the production process, and optimization algorithms can handle it along with all the other raw materials so as to get the most output from the least input.
Iron ore pelletizing systems
Iron ore can be upgraded to a higher iron ore content through beneficiation. This process generates iron ore filter cake which needs to be pelletized to be used in the steel making process. Also during the processing of high grade iron ores which don't need beneficiated, fines which are generated can be pelletized and used instead of being disposed of.

Mining and Refining – Process World Aluminium
Alumina is used for the production of aluminium metal, through the Hall–Héroult electrochemical smelting process. The Bayer Process is the most economic means of obtaining alumina from bauxite. Other processes for obtaining alumina from metal ores are also in use in some refineries, particularly in China and Russia, although these make up a relatively small percentage of global production.
The Hittites Iron smelting before the Iron Age
Iron probably was not the mythical secret weapon which explained Hittite military success. However, they did develop a smelting process capable of producing iron tools, weapons, and ornamental objects. Their process was the result of years of metalworking experience, not simply an accidental byproduct of an iron rock falling into a fire.
