The test work showed that co treatment of limonitic ore with either pyrrhotite concentrate or copper nickel concentrate was effective with base metals present in the laterite ore and sulfide concentrates being extracted up to % of Ni and % Cu and oxidation of the iron sulfide component generating the required acid for leaching
The main raw material is copper sulfide ore and high grade copper oxide ore can also be smelted in the pyrometallurgical process The mining grade of copper sulfide is 2% and the average mining grade is approximately % The mined ore is crushed and pulverized Then flotation will separate the copper sulfide concentrate
1 Introduction Flotation a physicochemical separation process that exploits the difference in the surface properties of valuable minerals and unwanted gangue minerals is currently the most important and versatile mineral processing technique [1] It utilizes the hydrophobic aerophilic nature of mineral surfaces and their tendency to attach to rising air
The period from about 1880 to 1910 shows nickel produced from the laterite ores of New Caledonia dominating nickel production—by about 1910 world nickel production was about 10 000 ton/a Figs 1 and 2—when nickel from Sudbury sulphide ore started to dominate After about 1950 nickel from laterite slowly increased

where the heavier sample of the same rock size is classified as a sulphide Examples of sulphide and non sulphide specimens are illustrated in Figure 1 Figure 1 Non sulphides left and sulphides right Dual Energy X ray Transmission DE XRT The Dual Energy X ray Transmission DE XRT technology measures the X ray at
Zhang et al proposed ammonium sulphate technology for the complex zinc dust with high F and Cl Although there are many reports on the recovery of zinc oxide ore or zinc metallurgical slag and dust [3 8 9] researches on extractive of oxide sulphide zinc ore are scarce On this basis three different processes are designed which are
The choice of copper ore processing technology depends on its composition the sulfide oxide carbonate and copper silicate content Leaders in copper ore processing include Chile Peru the United States Australia China Russia Mexico Kazakhstan Zambia and Congo Chile accounted for almost a third of global copper production in 2018

The effect of seawater on sulfide ore flotation includes micro and macro Powder Technology Volume 431 2024 Article 119049 Yuqi Miao Tingsheng Qiu Effect of Mg 2 and Ca 2 as divalent seawater cations on the floatability of molybdenite and chalcopyrite
Department of Materials Engineering Faculty of Industrial Technology Institut Teknologi Sepuluh Nopember Arief Rahman Hakim Street Surabaya East Java 60111 Indonesia more expensive than nickel sulphide ore processing This is because Ni content of nickel laterite ore is more difficult to upgrade Unlike nickel sulphide ore the
Ore samples used in this paper are from a polymetallic carbonate replacement deposit gold silver lead zinc sulphide in Southeast Europe This paper focuses on how the Dual Energy X ray Transmission DE XRT data is generated and used for ore characterization and sortability for this sulphide ore
VMS ore forming fluids are acidic reduced 1 3 M chloride solutions in which metals were transported mainly as chloride complexes Table 3 Before the discovery of black smokers temperatures of the ore fluids were estimated from rare fluid inclusion data and sulfur isotope fractionation between sulfide mineral pairs pH values about 1 unit less than neutral 5 at 250
In this work a two step vacuum metallurgy method was proposed to produce Sb2S3 from complex lead antimony sulfide ore As revealed from the experimental results jamesonite Pb4FeSb6S14 is overall decomposed into PbS Sb2S3 and FeS at 750 °C The first step vacuum distillation was performed at 650 °C for 80 min by which the purity of Sb2S3

This research aimed to optimize the experimental conditions of biodesulfurization of sulfide ore and to evaluate the flame retardant effect after desulfurization under optimal conditions Six experimental factors were determined particle size of ore sample ambient temperature rotary speed of the shaking table volume of bacteria liquid concentration of
The current technologies based on pyrometallurgy used to extract metals from ores use vastly more energy than is theoretically required [26] For example currently a sulfide ore might be roasted to create the oxide which is then reduced using carbon monoxide at high temperature Not only is much energy required to maintain the high
While the deposit qualities for mineral raw materials are constantly decreasing the challenges for sustainable raw material processing are increasing This applies not only to the demand for minimizing the consumption of energy water and reagents but also to the reduction of residual materials especially fine and difficult to landfill materials Sensor based ore sorting
In 1963 China successfully developed the process of antimony sulfide concentrate volatilization smelting in blast furnace which was a new technology for antimony production In 1986 China developed the chlorination hydrolysis process that directly uses antimony sulfide ore to produce antimony trioxide antimony white
The effect of microwave treatment on the grinding and flotation performance of a typical copper nickel sulfide ore was evaluated based on the determination of its microwave absorption capability grinding and flotation indexes such as crack percentage mineral liberation degree particle size distribution relative work index RWI metal enrichment ratio and
