Alternative siting of mine facilities Alternative loions for the mine itself are usually not up for discussion, because the ore deposit exists where it is. However, a mining company may be able to change from an openpit extraction method to an underground extraction method, to preserve surface resources. An underground mine might displace fewer human inhabitants and better protect ...

Mining is the process of extracting useful materials from the earth. Some examples of substances that are mined include coal, gold, or iron ore is the material from which the metal iron is produced. The process of mining dates back to prehistoric times. Prehistoric people first mined flint, which was ideal for tools and weapons since it breaks into shards with sharp edges.

Mining and ore processing. Ore is first mined at the open pit mine, then crushed, agglomerated, transported and stacked to the bioleaching heaps. Bioleaching . The bioleaching process utilises microbes to extract metals from ore. Air is blown into stacks of ore and the stacks are irrigated with an acidic production solution. This creates optimal conditions for microbial activity. Stacked ore ...
