“…Hydrometallurgical process for nickel sulfide ore was developed in 1970s, which is to transfer valuable metals to liquid phase from solid ore by chemical leaching, and then extracts valuable metals by solvent extraction, chemical Fig. 2 The typical flowchart of high-grade nickel matte production precipitation, crystallization, and other means [25][26][27]. Generally during a hydrometallurgical process of nickel sulfide ore, high-grade nickel matte or nickel concentrate is used as raw material.…”

With the vigorously growing demand of the steel industry, corrosion resistance alloys, clean energy industries, and a variety of engineered infrastructure or technology, high-grade nickel ores are being exhausted gradually in the world. This review outlines metallurgical processes for nickel production from various nickel sulfide ores resources, particularly focusing on recent developments in metallurgical processes to identify potential trends and technical requirements in nickel metallurgy. The main methods have been extensively reviewed for nickel extraction from nickel sulfide ores which maybe are potentially applicable to provide new ideas for smelting technology innovation of nickel and even other similar metals. The main metallurgical methods include pyrometallurgical and hydrometallurgy, containing smelting, leaching, and purification. The advantages and disadvantages of each typical process have been analyzed and compared in this review, and a special emphasis is put forth. Biological metallurgy is highly selective for recovery of nickel and the most promising method recommended for future research and development. Moreover, ion exchange offers useful method for extraction and purification of nickel. In addition, many of the typical new methods involved are also introduced in this article.

“…Polished ultra-pure zinc monosulphide was used for wetting tests. Contact angles were measured by sessile drop method at "ZnS-sulfur acid-gas", "ZnS-molten sulfur-gas" three-phase systems [8,9,13,14]. Elemental sulphur was preliminarily melted to form drop up to 2.5 mm, placed on mineral surface.…”

“…Problems of response surface blocking by sulfur and pellet formation can be eliminated by addition of surfactants, which change minerals wetting characteristics and sulfur properties. Lignosulfonates and petroleum-organic reagents can be used for controlling of these phenomena [8][9][10]. However, lignosulfonate usage at leaching leads to increase zinc dust consumption at solution purification from copper, nickel, cobalt, chlorine and current efficiency going down to 75-78 % [11,12].…”

This paper describes an investigation of the surfactant influence on zinc sulfide wetting and the pressure leaching of zinc concentrates. For this, a variety of anionic and cationic surfactants with different chemical structures were tested. The methodology for mineral preferential wettability determination via establishing correlation between the spreading coefficients was proposed. It allows determining the surfactant potential efficiency. The influence of contrastively functional reagents on zinc concentrate pressure leaching was reviewed. It is found that simultaneous usage of stabilizers and dispersing agents allows enhancing zinc extraction, eliminating pellet formation at lower reagent consumptions. The beneficial effect of surfactant mixture was seen through the increased zinc sulfide wetting by solution and colloid protection of sulfur particles via solvate-adsorption and structural factor of stabilization. The optimal composition of surfactant mixture was proposed and allowed to extract 95 % of zinc along with pellet formation elimination.

“…It was shown that in three different systems, pentlandite, nickeliferous pyrrhotite, and pyrrhotite that the work of adhesion was significantly lowered with the addition of quebracho, lignosulphonate, and humic acid. This implies that the additives should be good dispersing agents of the molten sulfur [35].…”

Abstract:This study provides an up to date review of tannins, specifically quebracho, in mineral processing and metallurgical processes. Quebracho is a highly useful reagent in many flotation applications, acting as both a depressant and a dispersant. Three different types of quebracho are mentioned in this study; quebracho "S" or Tupasol ATO, quebracho "O" or Tupafin ATO, and quebracho "A" or Silvafloc. It should be noted that literature often refers simply to "quebracho" without distinguishing a specific type. Quebracho is most commonly used in industry as a method to separate fluorite from calcite, which is traditionally quite challenging as both minerals share a common ion-calcium. Other applications for quebracho in flotation with calcite minerals as the main gangue source include barite and scheelite. In sulfide systems, quebracho is a key reagent in differential flotation of copper, lead, zinc circuits. The use of quebracho in the precipitation of germanium from zinc ores and for the recovery of ultrafine gold is also detailed in this work. This analysis explores the wide range of uses and methodology of quebracho in the extractive metallurgy field and expands on previous research by Iskra and Kitchener at Imperial College entitled, "Quebracho in Mineral Processing".
