New contributions to the understanding of Kiruna-type iron oxide-apatite deposits revealed by magnetite ore and gangue mineral geochemistry at the El Romeral deposit, Chile By P.A. Rojas, F. Barra, A. Deditius, M. Reich, A. Simon, M. Roberts and M. Rojo Together these deposits constitute 3.9 Billion Tonnes of JORC 2012 Inferred to Indicated resources (see ASX Announcements on 12/11/18 20/11/18). Since 2009, Magnetite Mines has invested AUD $35 million in the project by carrying out over 52,000 metres of drilling, completing a positive pre-feasibility study, and subsequent optimisation of that study.

These deposits form a regional-scale mineral system controlled by the Atacama Fault System and where the mineralization spans more than 10 km in vertical extent. Individual sub-vertical bodies of massive magnetite coexist with and evolve vertically into pegmatite-, breccia-, and vein-like apatite-actinolite-magnetite/ilmenite rock.

Iron oxide is a chemical compound made up of oxygen and iron, most abundant in the earth's crust in the form of Hematite (Fe2O3). It also exists in the form of Magnetite (Fe3O4). Iron Oxide is a mineral which varies in colour, from black or silver-grey to brown

As black sands, magnetite occurs in placer deposits, as in the Yukon and Columbia rivers. Most placer gold deposits contain significant magnetic black sand. Most large deposits of magnetite occur as segregations in igneous rocks, chiefly in the more basic rocks, gabbros, norites and sometimes syenites, as at Taberg and Kiruna, in Sweden, at the Adirondacks in the United States, and in the

Geology, Prospecting and Exploration for Iron Ore

Contact ores – Iron ore deposits formed at or near the contact between igneous rocks and sedimentary rocks are normally composed of magnetite and hematite with associated carbonates and pyrite. The ore deposits are usually in the sedimentary rocks as irregular or tabular replacement bodies.

Descriptions of major ore deposits world wide The Carmen de Andacollo porphyry copper gold deposit lies within the Andacollo district, which is hosted by the early Cretaceous shoshonitic volcanic arc of the Coastal Belt of Chile, some 480 km to the north of Santiago and 56 km south-east of La Serena (#Location: 30 15' 2S, 71 5' 40W).

Some beaches, often called black sand beaches, have heavy magnetite deposits. There are also significant, concentrated deposits of it and hematite, a mineral resulting from the reaction of magnetite with oxygen, in very old sedimentary rock formations known as banded iron formations.

There are magnetite deposits in Brazil, Chile, Canada, Australia, Madagascar and Malaysia. Shale oil and tar sands containing vanadium are present in North America and Queensland, Australia. Vanadium coproduct production from uranium mining in North America and Australia will contribute to vanadium supplies in the future.

Coastal placer deposits in the China Seas mainly exist in sandy and sandy-gravel coasts and formed primarily during the late Pleistocene and Holocene (Liu, 1989).Chen, Yang, et al. (2006) summarized distributions and divisions of placer deposits and ferromanganese nodules/crusts in the sea areas of China and outlined 3 prospecting zones and 24 divisions of the placer deposits (Figure 7.39).

Freehill Mining (ASX: FHS) reports extensive rock chip sampling and mapping at its El Dorado project in Chile has led to the discovery of three new mineralised targets. High-grade iron, copper and gold were present in the rock chip samples. El Dorado adjoins the

Large deposits of magnetite are also found in the Atacama region of Chile, Valentines region of with the highest dune at over 2,000 meters (6,560 ft) above the desert floor. The sand contains 10% magnetite. Crystals of magnetite have been found in some

2018/3/1In fact, magnetite is the most magnetic of all the naturally occurring minerals on Earth. Next time you go to a Great Lakes beach, take a magnet and see for yourself! There are other black sands around Lake Superior, including the sand on Black Beach in Silver Bay, Minnesota.

Silica-bearing magnetite was recognized in the Copiap Nordeste prospect as the first documented occurrence in Chilean iron oxide–copper–gold (IOCG) deposits. The SiO 2-rich magnetite termed silician magnetite occurs in early calcic to potassic alteration zones as orderly oscillatory layers in polyhedral magnetite and as isolated discrete grains, displaying perceptible optical differences

Magnetite occurs in nearly all igneous and metamorphic rocks and usually only in small particles or in a solution with other minerals. Some beaches, often called black sand beaches, contain heavy magnetite deposits. John Twomey, Magnetite Project Manager,
