Front-end loading (FEL), also referred to as Front-End Engineering Design (FEED), Front End Planning (FEP), pre-project planning (PPP), and early project planning, is the process for conceptual development of projects in processing industries such as upstream oil and gas, petrochemical, natural gas refining, extractive metallurgy, waste-to-energy, biotechnology, and pharmaceuticals.
Today the area has largely recovered from the scars left behind by the iron-mining boom days. The Gogebic Range has developed a tourism industry featuring ski resorts and waterfalls. After being clearcut during the unregulated lumbering era during the 19th and early 20th centuries, nearly the entire area has re-grown into extensive second ...

The East Texas iron ore belt refers to a significant region in East Texas characterized by the presence of iron ore deposits, primarily associated with the Weches greensand formation. This area has historical importance in the mining industry, contributing to the supply of iron ore in the United States .
Elemental iron is virtually absent on the Earth's surface except as iron-nickel alloys from meteorites and very rare forms of deep mantle xenoliths.Although iron is the fourth most abundant element in Earth's crust, composing about 5% by weight, [4] the vast majority is bound in silicate or, more rarely, carbonate minerals, and smelting pure iron from these minerals would require a prohibitive ...
Currently, after 150 years of mining, approximately 3 billion tons of ore have been produced. The relatively low iron content, however, meant that Lotharingian Minette-ore was successively replaced by more highly concentrated imported ores (with iron contents around 60%). As a consequence, more and more mines were closed down.

The Chilean Iron Belt is a geological province rich in iron ore deposits in northern Chile. It extends as a north-south beld along the western part of the Chilean regions of Coquimbo and Atacama , chiefly between the cities of La Serena and Taltal .
