Sulfur attaches to metal ions, creating a number of significant sulfide ore minerals such as galena (lead sulfide), pyrite (iron sulfide), chalcocite (copper sulfide), and sphalerite (zinc sulfide). Mined sulfur is mostly from salt domes or bedded deposits. The vast majority is produced as a by-product of oil refining and natural gas processing.

Sulfide ore (classified as "skarn-sulfide/massive sulfide ore") is located at depths of about 40 to 200 m (Rodmanee 2000) in which it yields the highest gold grade at 3.54 g/t (in massive sulfide) and 7.97 g/t (in skarn-sulfide).

The extraction of nickel (Ni) from sulfide resources commences with flotation to produce a concentrate which is then smelted to produce a nickel-enriched phase called matte, and further refined to produce pure Ni products as well as by-products, such as …

Geology of the main types of Ni sulphide ore deposits at Sudbury. b) ... (Figure 7) that are classified on the basis of spatial distributions, associations with silicate rocks, and metal contents ...

An early version of the schematic representation of komatiite flow-field facies and the volcanological setting of massive (Type 1) and disseminated (Type 2) nickel sulphide ore-bodies. This model was subsequently revised by Dr Hill using his research on active Hawaiian lava tube analogues.

Sulfide ore (classified as "skarn-sulfide/massive sulfide ore") is located at depths of about 40 to 200 m (Rodmanee 2000) in which it yields the highest gold grade …

Smith et al. (1976) ... Minerals can be classified into three broad groups, depending on whether they are attracted or repelled by a magnet: (1 ...

For some low-grade nickel sulfide ore from lean ore regions, for example, a sulfide mine in Shaanxi, China, due to the grade of nickel sulfide raw ore generally between 0.3 and 3.0%, it is necessary to enrich the ore by mineral processing before smelting. Sulfide ores are crushed and ground in order to liberate nickel minerals by …

Ore concentration is the chemical process of eliminating impurities like sand, rocks, silt, grit etc. from the ore to extract the metals in their pure form. In other words, it is the method of separating ore from …

Sphalerite is a common sulphide and is the dominant ore mineral in Zn-Pb sulphide deposits. Precise determination of minor and trace element concentrations in sulphides, including sphalerite, by Laser-Ablation Inductively-Coupled-Plasma Mass-Spectrometry (LA-ICP-MS) is a potentially valuable petrogenetic tool. In this study, LA …
