Blake 1 ABSTRACT The Bureau of Mines investigated the mineralogy, tonnage, and bene­ ficiating characteristics of oxidized (nonmagnetic) taconite iron re­File Size: 7MB. The Bureau of Mines investigated the mineralogy, tonnage, and beneficiating characteristics of oxidized (nonmagnetic) taconite iron resources of the Western Mesabi Range.

Magnetic taconite currently provides about 95 pct of Mesabi production, but the large tonnages of oxidized taconite between the magnetic deposits will be needed to help meet.

Mineralogy and Geology of the Taconites and Iron Ores of the Mesabi Range, MinnesotaAuthor: John W. Gruner. The Mesabi Iron Range is an elongate trend containing large deposits of iron ore, and the largest of four major iron ranges in the region collectively known as the Iron Range of ered init is the chief iron ore mining district in the United States.

The district is located in northeast Minnesota, largely in Itasca and Saint Louis counties. the Mesabi Iron Range was very rich in high iron content iron ore. Most of the extremely high quality iron ore has already been mined, but there still is a lot of fair quality iron in the mines there.

Discovered init is the chief deposit of iron ore in the United States. The deposit is located in northeast Minnesota, largely in. The magnetic taconite Mineralogy and liberation characteristics of western Mesabi Range oxidized taconite book of the Mesabi Iron Range of Minnesota are typical BIF-type deposits.

They contain quartz, silicates, magnetite, hematite, siderite, and other carbonates (Gruner, ). They assay about 30% Fe with about 75% of the iron in the form of magnetite and the remainder is largely iron carbonate and iron silicate by: 2.

the Mesabi Range in where strip mining was the most common method used to gain access to the ore. The open pits mines and spoils banks formed from the removal of overburden to gain access to the ore are still present today.

As the rich ore was depleted taconite mining operations began. An Introduction to Mineralogy 5 (e.g. V, Cr, Mn, Fe, Co, Ni, and Cu) in oxide and silicate minerals causes them to be opaque or strongly colored so that the streak, the ma rk that they leave when Author: Cumhur Aydinalp.

Mesabi Range, especially those in the western portion of the formation. In Gruner expanded his work to include a much more detailed examination of the mineralogy of the iron-bearing rocks of the Mesabi Range.

The iron formation is comprised of a vast array of minerals both primary and metamorphic in origin. The major minerals of the File Size: 3MB. The treatment of auriferous ores presents several challenges to the metallurgists and plant operators due to there are some factors that have an important impact on the process.

Without any doubt the mineralogy is the key aspect of the process performance. Basically, there are several options to be considered at the moment of evaluate the ore.

The first alternative is a gravimetry process and. The Mineral Liberation Analyzer (MLA) is an automated mineral analysis system that can identify minerals in polished sections of drill core, particulate or lump materials, and quantify a wide range of mineral characteristics, such as mineral abundance, grain size and liberation.

Prediction of carbonate mineralogy and carbonate mineral chemistry is an important goal of ore characterisation for pelletising properties.

Contact metamorphism causes changes in mineralogy and grain size (Klein, ; Gunderson and Schwartz, ). Increasing the grain size of magnetite should improve its liberation characteristics.
