what machine were used during the process of mining iron ore

There are four main mining methods underground open surface (pit) placer and in-situ mining Underground mines are more expensive and are often used to reach deeper deposits Surface mines are typically used for more shallow and less valuable deposits Placer mining is used to sift out valuable metals from sediments in river channels beach sands or other environments In-situ mining Iron ore is the raw material used to make pig iron which is one of the main raw materials to make steel—98% of the mined iron ore is used to make steel Indeed it has been argued that iron ore is more integral to the global economy than any other commodity except perhaps oil

Yet mining the ore is just one stage in a long and complex gold mining process Long before any gold can be extracted significant exploration and development needs to take place both to determine as accurately as possible the size of the deposit as well as how to extract and process the ore efficiently safely and responsibly

How Are Diamonds Mined And Extracted From the Ground

To make mining efficient and effective the raw rock and soil are typically not examined on-site Instead they are transported to special plants where the ore is processed and the rough diamonds are extracted Depending on how rich the ore is a few hundred tons of ore might be sieved just to produce a single carat of gem quality rough diamonds

The iron ore trade is of course the trade of the Great Lakes but it was not always so The premier trade for so many years was grain then lumber took first place giving way subsequently to coal In fact it was not until 1888 that iron ore became the dominant trade of the Great Lakes Its beginnings were

In effect mining is the extraction of an ore or minerals for example iron ore from the earth generally by means of tunneling or excavation Although much of the earliest iron ore used in Europe was found in exposed areas of earth that did not require much digging these surface deposits were exhausted by the twelfth century and means of
