Volcanogenic massive sulfide ore deposit - Wikipedia

Volcanogenic massive sulfide ore deposits, also known as VMS ore deposits, are a type of metal sulfide ore deposit, mainly copper-zinc which are associated with and created by volcanic-associated hydrothermal events in submarine environments.. These deposits are also sometimes called volcanic-hosted massive sulfide (VHMS) deposits. The density generally is 4500 kg/m 3.

VOLCANOGENIC MASSIVE SULPHIDE DEPOSITS

typically occur as lenses of polymetallic massive sulphide that form at or near the seafloor in submarine volcanic envi-ronments. They form from metal-enriched fluids associated with seafloor hydrothermal convection. Their immediate host rocks can be either volcanic or sedimentary. VMS deposits are major sources of Zn, Cu, Pb, Ag and Au, and significant sources for Co, Sn, Se, Mn, Cd, In, Bi ...

Complex Sulphide Ores: Processing Options SpringerLink

Complex sulphide ores represent considerable reserves and resources in base non ferrous metals, in precious metals, and in sulphur. Some of their essential characteristics, which allow a general presentation of the complexity of their processing options, from the ore to the pure metals or finished products, have already been presented by the author (1,2).

The volcanogenic massive sulfide ore type is the most exploited type in Fennoscandia Shield. 16 The ore of Pyhäsalmi contains copper (Cu), zinc (Zn), iron (Fe), and sulfur (S). In general, the mineral composition of ore deposits varies in terms of changing ore minerals, their quantitative ratios, and even as variation in mineral forms. Thus, the enrichment process can suffer from variation of ...

MASSIVE SULPHIDE DEPOSITS - Earth Sci

The average massive sulphide camp in Canada has about 9 deposits, but ranges from four (Manitowadge) to 21 (Noranda), However, an individual deposit may consist of a number of closely associated, discrete lenses ranging from several thousand to several million tons in size (ea. Millenbach Mine was 16 geologically discrete ore lenses). The largest deposits in this group may be in excess of

Base Metal Ores - an overview ScienceDirect Topics

During flotation of gold-bearing massive sulphide ores, the emphasis is generally placed on the production of base metal concentrates and gold recovery becomes a secondary consideration. In some cases, where significant quantities of gold are contained in base metal ores, the gold is floated from the base metal tailings.

3 Antimony Ore Beneficiation Process - Mining-pedia

Antimony ore can be divided into antimonite, cubismite, antimony ochre, etc. Due to the difference in the nature of the ore, the process used is also different. Commonly used beneficiation processes include manual separation, gravity separation and flotation . This article briefly introduces these three commonly used antimony ore beneficiation processes.

The massive sulfide normally sits upon a footwall of basalt or felsic volcanic rock, into which the massive sulfide may locally intrude, forming veins, interpillow sulfides, and interbreccia sulfides. Semi-massive sulfides are more common and are composed of 75-90% Fe-Ni-Cu sulfides with inclusions of olivine and wall rocks. Net-textured sulfides (Canada) or matrix sulfides (Australia) are ...
