Underground mining is used to recover ores that are deeper into Earths surface. Miners blast and tunnel into rock to gain access to the ores. How underground mining is approached from above, below, or sideways depends on the placement of the ore body, its depth, concentration of ore, and the strength of the surrounding rock.

Exploration is the process by which the accumulations of iron ore minerals can be found in the earths crust. Before the heavy investments required to set up a mining operation is done, the mining organization is to ensure that the deposit is economically viable and it has quantities of ore that will ensure ore production over a sufficiently long period of time.
Ore, a natural aggregation of one or more minerals that can be mined, processed, and sold at a profit. An older definition restricted usage of the word ore to metallic mineral deposits, but the term has expanded in some instances to include nonmetallics. Although more than 2,800 mineral species
2 #0183;#32;Comminution (, the breaking of rock to facilitate the separation of ore minerals from waste) combines blasting (a unit process of mining) with crushing and grinding (processing steps). Insitu mining, which is treated under a separate heading in this chapter, is a special case that combines aspects of mining and processing but does not require the excavation, comminution, and waste
Ecoefficient and costeffective process design for, Ecoefficient and costeffective process design for magnetite iron ore. Currently, the mining industry is facing several issues related to energy consumption so the optimized use of energy is an everincreasing Ore Processing for the Blast Furnace,The process of mining low grade iron ore, or taconite, requires massive resources.
Ore forming process where dense gold particles and diamonds are concentrated by flowing water in rivers and at beaches. Placer mine Type of surface mineral mine which extracts gold or diamonds from river and beach. sediment by scooping up the sediment and then separating the ore by density.
Copper Mining and Processing: Everything you Need to Know The Basics of Copper Mining and ProcessingWhat Is Copper Used for?The Copper Mining Process Once its located within the earth, copper ore goes through eight stages before the consumer sees it in various products that affect every day life in the home and business. These eight stages include: 1.
Hydrothermal process Hydrothermal process is the most common ore forming process. Water is heated by the magma chamber and this water dissolves metals. Metals are dissolved in the water and this solution seeps through cracks, fractures and through permeable rocks until they are precipitated and form a
1. Mining open pit and underground. To define the ore from the waste rock, samples are taken and assayed. Assay results are used to mark out areas of ore and waste rock, which are mined separately. Some of the harder areas require blasting to loosen the rock prior to excavation by hydraulic diggers.
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 value of the ore body.
Generally, the ore and the gangue are mined, taken out of the host rock in a mass by either mechanical or manual means. Then the ore is separated from the gangue by various operations known collectively as mineral processing, or ore dressing.

#0183;#32;The mining process is responsible for much of the energy we use and products we consume. Mining has been a vital part of American economy and the stages of the mining process have had little fluctuation. However, the process of mining for ore is intricate and requires meticulous work procedures to be efficient and effective. This is why we have
