The Major Steps In The Process Of Mining Iron

Iron ore as mined is a combination of iron with oxygen and various other unwanted substances generally known as gangue the first metallurgical step is to reduce iron ore to metallic iron a process which is mostly carried out in a blast furnace using coke as both a fuel and reducing agent

Mar 14 2014 the process of mining consists of discovery of an iron ore deposit through extraction of iron ore and finally to returning the land to its natural state it consists of several distinct steps the first is discovery of the iron ore deposit which is carried out through prospecting or exploration to find and then define the extent location and

Copper processing is a complicated process that begins with mining of the ore less than 1 copper and ends with sheets of 9999 pure copper called cathodes which will ultimately be made into products for everyday most common types of ore copper oxide and copper sulfide undergo two different processes hydrometallurgy and pyrometallurgy respectively due to the different

When the iron ore is extracted from the mine it must undergo several processing stages six steps to process iron ore 1 screening we recommend that you begin by screening the iron ore to separate fine particles below the crushers css before the crushing stage a static screen is used to divert the fine particles for crushing

The process of extracting iron from ore produces great quantities of poisonous and corrosive gases in practice these gases are scrubbed and recycled inevitably however some small amounts of toxic gases escape to the atmosphere a byproduct of iron purification is slag which is produced in huge amounts
