Magnetite And Copper Ore Element

Magnetite is the most common ore mineral in magmatic and hydrothermal iron-rich deposits (e.g., Fe-Ti oxide, iron oxide copper gold (IOCG), porphyry, skarn, and iron oxide apatite (IOA or Kiruna-type)) (Dupuis and Beaudoin, 2011, Dare et al., 2012, Dare et al., 2014, Nadoll et al., 2014).The texture and geochemistry of magnetite vary considerably from different ore …

Current magnetite production is a by-product of the copper operations and as such is recovered from the Concentrator floatation tails stream by magnetic separation. Approximately 15%, by weight, of magnetite is removed by 'cleaning' and 're-cleaning' of …

Magnetite is the most important iron ore in iron oxide-apatite (IOA) deposits which represent the Cu-poor endmember of the iron oxide-copper–gold (IOCG) clan. Magnetite chemistry has been used as a petrogenetic indicator to identify the geological environment of ore formation and as a fingerprint of the source reservoir of iron.

In this work, the copper oxide ore from Congo responded well to magnetic separation, for raw ore containing 1.50 % Cu of −2 mm size fraction, under magnetic separation under 1.5 T magnetic induction intensity, 3 mm rod matrix and 100 r/min pulsating, magnetic concentrate with 76.63 % Cu recovery and 8.60 % Cu grade was obtained, the content ...

The origin of stratabound deposits in the Middle-Lower Yangtze River Valley Metallogenic Belt (MLYRB), Eastern China, is the subject of considerable debate. The Xinqiao Cu-Fe-Au deposit in the Tongling ore district is a typical stratabound ore body characterized by multi-stage magnetite. A total of six generations of magnetite have been identified. Mt1 is commonly replaced by …

The project main objectives are to: 1) geologically, characterize the setting and origin of the iron-copper-cobalt-gold-rare earth element deposits, and advance the knowledge of rare earth element and Co potential within iron oxide-copper-gold (IOCG) deposits of southeast Missouri, and 2) geophysically delineate and characterize the subsurface Precambrian geology using existing …

The Non-BIF Iron ore bodies of different dimensions have been reported from the North Delhi Fold Belt, surrounding the Khetri copper deposit (Fig. 1, Fig. 2), and are distributed over parts of Rajasthan and adjoining Mahendragarh district of Haryana (Pant et al., 2004).The magnetite bodies associated with the sulfide minerals from the Khetri copper deposit have …

The subtle variations of trace element concentrations within a magnetite grain and between the magnetite grains in the same sample probably indicate local inhomogeneity of ore–forming fluids. The variations of Co in magnetite between samples are probably due to the mineral proportion of magnetite and pyrite.

Magnetite is a common mineral in many types of ore deposits, including Kiruna-type, BIF (banded iron formation), magmatic Fe-Ti oxide, Fe-skarn, IOCG, and porphyry deposits, and also in many ...

We present detailed textural and compositional data on magnetite from the Paleozoic Shuanglong Fe-Cu deposit to constrain the formation of iron oxides and the evolution of the ore-forming fluids and thus define the genesis of the Fe-Cu ores.

The trace element composition of igneous and hydrothermal magnetite from 19 well-studied porphyry Cu ± Au ± Mo, Mo, and W-Mo deposits was measured by laser ablation-inductively coupled plasma-mass spectrometry (LA-ICP-MS) and then classified by partial least squares-discriminant analysis (PLS-DA) to constrain the factors explaining the relationships …

The present study is focused on the iron ore occurrences in the southern and south-eastern part of the Khetri copper deposit where a good number of iron ore bodies of mineable scale (Fig. 3) are found within the albitites and meta-sedimentary rocks belonging to Alwar and Ajabgarh Group of Delhi Supergroup.The magnetite found from the Khetri Copper deposit is …
