Open Access Challenges in Sulphide Mineral Processing

2016-6-11  sulphide mineral–water interfaces, are still unresolved or poorly understood. The sulphide minerals are the most important, most di-verse, and richest in terms of physical, chemical, and struc-tural properties. Such diversity originates from the more complex crystal and electronic structures compared to other classes of materials [2].

Revisiting sulphide mineral (bio)processing: a few

Most likely H2O2 is responsible for the oxidation of sulphide minerals and dissolution of non-ferrous metal sulphides in the presence of ferrous sulphide in addition to galvanic interactions.

Principles and practice of sulphide mineral flotation

Synopsis. This paper presents both the fundamentals of sulphide mineral flotation and the practical aspects of sulphide ore flotation. The fundamental aspects of the flotation of sulphide minerals both in the absence and presence of thiol collectors are discussed in relation to their crystal structure, surface chemistry and electrochemical characteristics.

MINERAL TESTS CONFIRM ECONOMICAL GRADE

The mineral studies determined the predominant Ni-sulphide mineral to be pentlandite ([Fe,Ni]9S8) with very minor millerite (NiS) and violarite (Fe2+Ni3+2S4). Silicate minerals, iron oxides and chromite contain relatively low nickel concentrations. The main silicates minerals include serpentine, pyroxenes, amphibole and

Mineral leaching of non‐sulphide nickel ores using

Laboratory studies were conducted on microbial leaching of non‐sulphide nickel ores not amenable to conventional mineral processing operations. The results showed that extensive low‐grade laterite domestic sources are generally amenable to bioleaching when micro‐organisms were cultivated in the presence of the ore.
