Formation of magmatic nickel-sulfide ore deposits and

Nickel-copper sulfide ore deposits are found at the base of mafic and ultramafic bodi All their host rocks, except the Sudbury Igneous Complex, are thought to be mantle derived melts The Sudbury Igneous Complex is thought to be the product of complete melting of continental crust In the case of mantle-derived magmas, a high degree of partial melting of the mantle serves to enrich the.

The Mineral Gallery

The Sulfide Class minerals comprise an economically important class of minerals Most major ores of important metals such as copper, lead and silver are sulfid Strong generalities exist in this class The majority of sulfides are metallic, opaque, generally sectile, soft to average in hardness and they have high densities, black or dark-colored streaks, and an igneous origin.

INTRUSION-RELATED DEPOSITS

ENVIRONMENT: Similar environments and host rocks as chromite and nickel-copper (Platinum refers to an element, a mineral and a mineral group Three main deposit types (only concerned with magmatic here): 1 MAGMATIC i) Associated with stratiform chromite mineralization in layered intrusions In many cases as the primary product associated with.

Metallic Deposits

Metals such as chromium, platinum, nickel, copper, and iron can precipitate as sulfide minerals in a cooling body of magma Magmatic deposits result when the minerals settle to the bottom of the intrusive body and form thin, high‐grade layers.

HIGH GRADE NICKEL-COPPER SULPHIDES

Extensive mining of Nickel Sulphide deposits has meant that large scale high grade deposits of this type are being depleted at a faster rate than discovery In terms of production Class 1 Nickel has preferentially been sourced from magmatic Sulphides as these are significantly easier and cheaper to mine and process than Lateritic or.

Controls on the Formation of Komatiite-Associated Nickel

Abstract Nickel-copper sulfide deposits associated with rocks of komatiitic affinity may be divided into two associations on the basis of host rock composition and ore distribution: (1) stratiform, massive-matrix-disseminated sulfides hosted by cumulate komatiite lava flows (lava conduits), or strata-bound, coarse disseminated sulfides hosted by cumulate komatiite bodies near volcanic vents.

Thomson Resources

Magmatic Nickel Deposit Model Nickel deposits fall into three main types - Archaean komatiite hosted deposits, laterite nickel deposits and magmatic nickel sulphide deposits A fourth type (hydrothermal) is emerging in importance Australia’s eastern states with discoveries in Tasmania and Queensland.

Magmatic Sulphide

Magmatic Sulphide If a mafic to ultramafic melt becomes saturated in sulphur (generally because of contamination from crustal-derived sulphur), an immiscible liquid sulphide phase will form, into which nickel, cobalt and platinum-group elements (PGE) preferentially partition.

201 Metal Deposits

Magmatic Nickel Deposits A magmatic deposit is one in which the metal concentration takes place primarily at the same time as the formation and emplacement of the magma Most of the nickel mined in Canada comes from magmatic deposits such as those in Sudbury (Ontario), Thompson (Manitoba) (Figure 204), and Voisey’s Bay (Labrador).

Nickel-Copper-PGE Deposits

Ore genesis

Nickel is a chalcophile element which prefers sulfides, so an ultramafic or mafic rock which has a sulfide phase in the magma may form nickel sulfid The best nickel deposits are formed where sulfide accumulates in the base of lava tubes or volcanic flows — especially komatiite lavas Komatiitic nickel-copper sulfide deposits are considered.
