Sustainability-Environmental-Waste Management, Recycling

Waste rock and surface material must be removed to uncover the taconite that will be processed. Waste rock and surface overburden are stockpiled around the active mining area, in compliance with state guidelines for stockpiles and reclamation. Approximately 70% of the processed taconite is non-iron bearing material that is generated as tailings.

PDF Injection of coal and waste plastics in blast furnaces

There are various alternatives for recycling waste plastics. Mechanical (or materials) recycling is considered to be the best method, whereby the waste plastics are melted and iron ore, and around 20% of the energy in the remaining 40% of the gases is utilised as a fuel within the steelworks (Ogaki and others, 2001; Wakimoto, 2001).

Mine Waste in the Eastern Adirondacks May be Untapped

Dec 22, 2020 · The eastern Adirondack Mountains in upstate New York were heavily mined for iron in the 1800s and 1900s and played an important role in industrialization of the Northeast prior to and during World War II. The mining activities resulted in piles of waste rock and mill tailings (the residuals of ore processing) in various areas throughout the region.

Recycling of steel plant mill scale via iron ore sintering

The mill scale contains high amounts of Fe and low amounts of silica and alumina. Thus, recycling it through the sintering process helps in the saving of raw materials like iron ore and limestone. This paper presents preliminary findings of a study that investigates the potential for recycling steel mill scale in the sintering process.
