A lesserused method of transportation is an iron ore slurry pipeline. Iron Ore Beneficiation Iron ore occurs naturally in a variety of forms, from sandlike iron fines to solid rock masses. Crude ore, or ore mined in the natural state, seldom occurs in a pure state and requires some form of beneficiation.
2. ORE BENEFICIATION METHODS IN MINING The primary objective of mining is to supply raw materials to downstream users, extracted from ore deposits in the earth‟s crust, using applicable excavation and ore enrichment processes with economically feasible and environmentally sound engineering operations.
Atomic spectroscopy is one of the most widely used methods for quantitative elemental analysis. There are a number of situations where elemental composition is important –, how much iron in an ore sample, how much lead in your drinking water, calcium in intracellular fluids. In a sense, it's the simplest type of analysis, since

Iron ore is the source of primary iron for the world's iron and steel industries. It is therefore essential for the production of steel, which in turn is essential to maintain a strong industrial base. Almost all (98%) iron ore is used in steelmaking. Iron ore is mined in about 50 countries.
May 21, 2019· Methods such as screening, crushing, and grinding of iron ore are often used in various ways to purify it, along with several stages of magnetic separation. The iron ore industry classifies the material by the concentration of the metal that is present after iron ore beneficiation has been completed.
The mining industry consists of the search for, extraction, beneficiation, and processing of naturally occurring solid minerals from the earth. These mined minerals include coal, metals such as iron, copper, or zinc, and industrial minerals such as potash, limestone, and other crushed rocks. Oil and natural gas extraction (NAICS code 211) is not included in this industry.
