Reconnaissance-scale conceptual fuzzy-logic prospectivity modelling for iron oxide copper–gold deposits

processing and evaluation time. In this paper, a prospectivity (or endowment) map is presented for iron oxide copper–gold (IOCG) deposits in the northern Fennoscandian Shield, northern Finland (Figure 1) at 1:1 000 000 reconnaissance scale. The IOCG

Iron Oxide Copper-Gold DepositsGeology, Space-Time

Iron oxide copper-gold deposits are considered to derive from magmatic-hydrothermal fluids exsolved from crust-contaminated calc-alkaline melts (Hitzman et al., 1992;Pollard, 2000;Sillitoe, 2003

Iron oxide-copper-gold deposits: an Andean view |

Iron oxide-copper-gold (IOCG) deposits, defined primarily by their elevated magnetite and/or hematite contents, constitute a broad, ill-defined clan related to a variety of tectono-magmatic settings. The youngest and, therefore, most readily understandable IOCG belt is loed in the Coastal Cordillera of northern Chile and southern Peru, where it is part of a volcano-plutonic arc of Jurassic

(PDF) Gold in iron oxide copper–gold deposits

Iron oxide-copper-gold (IOCG) deposits are distinguished by higher copper grades than porphyry copper deposits (mostly > 1%) and wide range of low grade gold (Sillitoe, 2003).

[PDF] Iron Oxide Copper-Gold (IOCG) Deposits

The iron oxide copper-gold (IOCG) group of deposits, initially defined following discovery of the giant Olympic Dam Cu-U-Au deposit, has progressively become too-eracing when associated deposits and potential end meers or analogs are included. The broader group includes several low Ti iron oxide-associated deposits that include iron oxide (P-rich), iron oxide (F- and REE-rich), Fe or Cu-Au

Iron oxide copper gold ore deposits - Wikipedia

Iron oxide copper gold ore deposits (IOCG) are important and highly valuable concentrations of copper, gold and uranium ores hosted within iron oxide dominant gangue asselages which share a common genetic origin. These ore bodies range from around 10 million tonnes of contained ore, to 4,000 million tonnes or more, and have a grade of

Magnetic and Gravity Gradiometry Framework for

The data are used to calculate mineral prospectivity for iron oxide-apatite (IOA) ± rare earth element (REE) and iron oxide-copper-gold (IOCG) deposits. Results delineate the geophysical footprints of all known iron oxide deposits and reveal several previously unrecognized prospective areas.

how to process gold ore from copper in china

Copper Ore Processing Methods The four major steps in the production of marketable copper are mining, concentrating, smelting, and refining in a few instances, however, leaching takes the place of concentrating, smelting, and refining at present, although considerable leaching and directsmelting ores are produced, the bulk of the copper ore mined is concentrated the milling of copper ores as

Iron Oxide-Copper-Gold (IOCG) Deposits of Australia |

7/8/2013· Iron oxide-copper-gold or IOCG deposits can be of tremendous size. The largest known deposit of this type is Olympic Dam, loed 560 kilometres north of Adelaide, South Australia. Olympic Dam is Australia’s largest underground mine.In 2012, plans to expand

Gold Processing Methods & Gold Ore Extraction

Of all the methods of extracting gold & processing it from its ore, I used a few to evaluate two principal flowsheets in this case study. The flowsheets utilized operations that involved flotation, cyanidation and gravity concentration. Tests that mirror each of these unit operations were utilized to evaluate the principal flowsheets. This page offers a comparative review of gold recovery

Silica-bearing magnetite was recognized in the Copiapó 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
