(PDF) Characteristics and models for Carlin-type gold deposits

The aim of this work is to describe the mineralogy of the Ag-Pb-Zn-Cu-Sb second stage of mineralization of Arcos, as well as the chemical composition of their most representative ore minerals.

Sedimentary Exhalative (Sedex) Zinc-Lead-Silver Deposit Model

Sedex Pb-Zn-Ag deposits Synonyms The term sedex, derived from sedimentary exhalative (Carne and Cathro, 1982), is based on the interpretation that the finely laminated or bedded sulfide ores that characterize this deposit type are chemical sediments that precipitated from hydrothermal fluids that had been "exhaled" or vented onto the sea floor.

Copper-Lead-Zinc ores - Danafloat

Copper-Lead-Zinc ores The Cu-Pb-Zn separation process is among the most challenging flotation separations primarily because the first step must entail bulk flotation of the two most readily floatable minerals with these two minerals separated in a differential flotation stage.

CANATUAN CU/ZN FLOTATION METALLURGY

The nature of Canatuan sulphide deposit allowed the staged processing of the ore from high Cu-low Zn ores to low Cu-high Zn ores. Due to this mineralogical stratification, emphasis on the high Cu-low Zn ores was set for the initial 1-2 years of operation. This provided some time to gather enough plant data

Zn/Cd ratios and cadmium isotope evidence for the ...

Apr 28, 2016· Lead-zinc (Pb-Zn) deposits are typically classified by their ore-formation processes and geological settings. Such deposits can be formed by the discharge of deep sedimentary brine onto the sea floor (sedimentary exhalative; SEDEX) or by replacement of limestone (Mississippi Valley type; MVT) 1,2, whereas some are associated with submarine volcanoes (volcanogenic massive sulfide; VMS) or …

Sequential Copper–Lead–Zinc Flotation

To improve the selectivity between copper and lead, a sequential copper-lead-zinc rougher circuit was tested. Each of the rougher circuits had a dedicated regrind and cleaner circuit. The advantages of the sequential circuits are that the levels of selectivity can be increased, particularly for copper and lead. With this process, copper was recovered first with MBS depression of lead, zinc and ...

2.7 Orogenic mineral system | Geoscience Australia

The orogenic mineral system (Figure 2.7.1) unites a diverse group of mineral deposits that form during orogenesis, and include lode gold and Cobar-type Cu-Au-Zn-Pb-Ag deposits. These deposits form in response to major orogenic events caused by accretion or changes in subduction direction or dip.

Geochemistry of hydrothermal gold deposits: A review ...

Although ore-forming fluids derived from magma are common, hydrothermal systems without distinct affinities to magmatic activity can also result in the formation of large hydrothermal ore deposits (e.g., Au, Ag, Pd, Zn, Sb, Hg, etc.). A significant portion of the world's natural gold endowment comes from hydrothermal ore deposits (Frimmel ...

Sulfur and chlorine are the two most important ligands accounting for metal transport in the upper crust. In this study, four metal- and sulfur-saturated model fluids with varying salinities and redox states were simulated in the Fe-Cu-Pb-Zn-Au-S-C-H-O system, over a wide pressure-temperature (P-T) range (50-650 0 C, 0.8-5.0. kbar), in order to compare the roles of chloride and bisulfide ...

Gold Skarns - British Columbia

The ore in both reduced and oxidized types tends to have low Cu:Au (<2000), Cu:Ag (<1000), Zn:Au (<100) and Ag/Au (<1) ratios. Gold is commonly present as micron-sized inclusions in sulphides, or at sulphide grain boundaries. It is often associated with tellurides. To the naked eye, Au skarn ore is generally indistinguishable from waste rock.
