Make preparations to meet local environmental regulations for an open pit mine. Using open pit mines, also known as quarries, is the best way to extract hard rocks such as coal, copper, gold, and iron ore. Certain areas have environmental regulations that will include your mine. You will need to contact your local environmental management group to see exactly how your area regulates quarries. Most likely, there will be regulation for air and water quality around your site. You need to make preparations to meet these regulations. For example, you might have to build extra structures near your mine to prevent water runoff from becoming contaminated by your mine.
Design your mine in a way that the land can be reclaimed. It can be reused for other purposes if you properly preserve nearby top soil, minimize erosion and properly dispose of wastes such as inorganic trash. Many of the regulations relating to land reclamation will go hand-in-hand with environmental regulations.
Cut an open pit mine with benches, which are essentially ledges that span the outside of each layer of the mine and allow basic functions such as movement of mining personnel and removal of rock. Most mines will have several benches in operation at once, all of which lead to the bottom of the mine, known as the pit bottom. At low depths, mines can be dug using conventional digging equipment such as hydraulic excavators. When you reach rock, these methods will no longer be effective and you will need to use explosive such as dynamite.
Begin mining ore. Ship it to a processing facility. Here, the ore with the highest concentration of iron, those with at least 60 percent iron, will be separated and refined. Pure iron is then shipped to a furnace site where it is blasted and then poured, a process that shapes it.
