Currently there are four large-scale industrial mines (two in gold production and two producing iron ore) operating in Liberia with several others into exploration and mine development for both gold, but mainly iron ore (Table 1).
What are the disadvantages of iron ore?
However, mining of iron ore has copious negative impacts on the environment. As the mining method for Iron is usually open cast, it degrades natural landscapes, surface and ground water, flora and fauna, as well as the ambient air quality within the mining area and its environs.
Where can we find iron ore in Liberia?
Liberia has large resources of itabirite-type iron ores, most of which are located in the Liberian terrane, and was the largest producer in Africa prior to the onset of civil war in 1989. Production of iron ore is currently restricted to a single mine, Yekepa, in the Nimba Range.

What are the advantages and disadvantages of iron?
A skilled blacksmith can work heated iron into just about any shape imaginable. Iron is an incredibly useful substance. It’s less brittle than stone yet, compared to wood or copper, extremely strong. If properly heated, iron is also relatively easy to shape into various forms, as well as refine, using simple tools.
What are the biggest disadvantages of using iron or steel?
Disadvantages of Structural Steel Structures
- Steel is an alloy of iron.
- It has high maintenance costs as it has to be painted to make it corrosion-resistant.
- There are extensive fireproofing costs involved as steel is not fireproof.
- Buckling is an issue with steel structures.
Where are diamonds found in Liberia?
In Liberia, diamonds are produced solely from alluvial placers by artisanal miners located in the west and central parts of the country. Liberia has a long history of alluvial diamond production, with an output of about 14 million carats during the last 50 years.
What is a beneficiation plant?
Beneficiation Plant means any plant or unit that is used for the purpose of processing of minerals to get rid of gangue, or to obtain a final product e.g. custom milling plant, cyanidation plant, elution plant, blast furnace, agglomeration plant, smelter, refinery, concentrator or any other place as provided.
What do you mean by ore beneficiation?
From Wikipedia, the free encyclopedia. In the mining industry or extractive metallurgy, beneficiation is any process that improves (benefits) the economic value of the ore by removing the gangue minerals, which results in a higher grade product (ore concentrate) and a waste stream (tailings).
What is iron ore?
Iron ore is a mineral substance which, when heated in the presence of a reductant, will yield metallic iron (Fe). It almost always consists of iron oxides, the primary forms of which are magnetite (Fe3O4) and hematite (Fe2O3). Iron ore is the source of primary iron for the world’s iron and steel industries.
What is the ndnimba Western Range iron ore project Liberia?
