Feb 21, 2011· One common type of gold deposit is one where the gold is associated with the mineral magnetite where the gold is formed in skarns of granular magnetite. The mineral has a chemical formula Fe 3 O 4 that is often found in contact metamorphosed areas associated with intrusions of magma into carbonate or silicocarbonate rocks the intrusion itself is usually granite or monzonite .
Magnetite is the only mineral that exhibits strong magnetism, although others like ilmenite, chromite and hematite may have weakly magnetic behavior. Magnetite has a Mohs hardness of about 6 and a black streak. Most magnetite occurs in very small grains. A chunk of wellcrystallized magnetite like the round specimen is called a lodestone.
Feb 28, 2011· Where can we find magnetite? In order to have a combination of 2+ and 3+ Fe present, magnetite requires at least a moderate fO2 value. At depth, magmas are usually more mafic to ultramafic in composition tend towards lower fO2 values. Typically, these more primitive magmas are waterpoor, which also influences their fO2 values.
Formula: Fe 2+ Fe 3+ 2 O 4 Isometric. Description: Magnetite is a common mineral found at many localities in Wisconsin. Only localities that where the mineral is present in great abundance or as unusual material are listed here.
The Magnetite Powder ore is commonly formed by the reduction of hematite and ferric hydroxide minerals in these rocks. Banded Precambrian iron formations commonly contain Magnetite Powder. Magnetite Powder is characteristically recognised by its strong magnetism, color and streak and is commonly used in dense medium separation techniques.
Magnetite is one of the most common iron minerals and an important ore of iron. ... Magnetite is a very common iron oxide (Fe 3 O 4) mineral that is found in igneous, metamorphic, and sedimentary rocks. It is the most commonly mined ore of iron. ... Use of Magnetite as an Ore of Iron.
The bulk of these rocks are either Hematite or Magnetite, and it makes almost 98% of the iron ore produced worldwide that goes into making steel. Much of the iron ore mined are oxide compounds of Magnetite (Fe 3 O 4 ), Hematite (Fe 2 O 3 ) Goethite (Fe 2 O 3 SH 2 O), and Limonite.
