Cobalt and nickel – tons of the metal in the form of an iron-nickel alloy. Nickel is also abundant in the cosmos. Iron meteorites contain an average of eight to nine percent of the sulfate of cobalt, nickel and copper, which contained so much iron that the remaining amount of arsenic could be precipitated out of it as iron arsenate.

Cited by: PHYSICOCHEMICAL CHARACTERIZATION OF COPPER SLAG AND ALTERNATIVES OF FRIENDLY ENVIRONMENTAL MANAGEMENT It is the case of the slags produced by the iron and steel, the copper and nickel sulphide, and the nickel laterite industries. copper, gold, nickel, cobalt and PGM’s [10, 11]. 3. Non Ferrous slags.

    Iron is one of the most common elements in the universe. Uncombined iron, cobalt, and nickel can be found in meteors. Cobalt. Like nickel, cobalt in the Earth’s crust is found only in chemically combined form, save for small deposits found in alloys of natural meteoric iron. The free element, produced by reductive smelting, is a hard. They investigated the effects of MgO and Al 2 O 3 additions to iron silicate slags on the activity coefficient of cobalt oxide, γ CoO, at oxygen partial pressure of 10 −9 to 10 −10 atm and °C. According to their findings, γ CoO increases with increasing concentration of .

Solubility of copper, nickel, and cobalt in iron silicate slags by Nelson Horacio Santander Download PDF EPUB FB2

The solubility of nickel and cobalt in silica saturated iron silicate slags in equilibrium with nickel-gold and cobalt-gold alloys has been investigated under controlled oxygen pressures in the temperature range of to °C.

It was found that the metal solubility increased with 1) decreasing temperature, 2) increasing oxygen pressure, and 3) increasing metal content of the by: variations in copper solubility for additions of alag constituents will help in the optimization of flux additions to minimise copper losses to the slag.

In a sulphur-free system, silica-saturated iron silicate slags ware equilibrated with copper-gold alloys under a nickel oxygon partial pressure of 8 x l(fP atm at ° K. The copper.

The solubility of nickel in slag was determined nickel equilibrating copper-nickel alloys with alumina-saturated iron silicate slags in an alumina crucible at K. The experiments were carried out under controlled oxygen partial pressures in the range of to atm by use of suitable CO-CO2 gas mixtures, and at Fe/SiO2 ratio The results showed that nickel dissolves in slag both as Cited by: 8.

Mintek has been working on the recovery of cobalt, and the associated valuable metals, from slags, sinceusing DC-arc furnace technology to effect selective carbothermic reduction of the oxides of cobalt, nickel, copper, (and zinc, where present), while retaining.

Experiments containing iron yield a formal valence of ; for Cu at very low oxygen fugacities, which is not observed in Fe-free systems.

The low formal valence is explained by redox reactions between iron and copper in the silicate melts. (SiO2, FeO, Fe3O4, CaO, Al2O3) and the content of copper in the matte on resulting copper content in the slag during smelting of the sulfide concentrates in the reverberatory furnace.

When comparing results obtained with MLRA model calculations with values measured at industrial level high degree of fitting is obtained (R2 = ). The solubility of Cu in silicate melts coexisting with liquid Cu(Fe) metal and liquid Cu(Fe) sulfide was determined experimentally at oxygen fugacities ranging from 10 − to 10 − bar and sulfur fugacities ranging from 10 − to 10 − bar at °C.

A heavy amount of slag ( tons per ton of copper) is generated during the pyro or hydrometallurgical copper production which generally contains significant amounts of some valuable metals such as copper, nickel, cobalt, and iron [1,2].In the last few decades, there has been growing interest in hydrometallurgical processes to recover valuable metals from smelter slags [].

The solubility of carbon in molten pure copper has been found to be about per cent carbon at C and per cent at C.(l) The solubility of carbon in manganese has been es-tablished by various investigators (3),(4),(5),(6)) to be about per cent carbon at C.

Cobalt is a chemical element with the symbol Co and atomic number Like nickel, cobalt is found in the Earth's crust only in chemically combined form, save for small deposits found in alloys of natural meteoric free element, produced by reductive smelting, is a hard, lustrous, silver-gray metal.

Cobalt-based blue pigments (cobalt blue) have been used since ancient times for Group: group 9. The electrical conductivities of the as-prepared copper, nickel, iron, and cobalt nanofibers were shown in Fig.

A along with the known bulk electrical conductivity [25].It can be observed that the second thermal treatment scheme, which generated a nanofiber void of an amorphous regions with isotropic crystals connected to each other, had the highest electrical conductivity of around 10 6.Nickel chloride is most water soluble; g/L at 20 o C, to g/L at o C.

Nickel carbonate has a water solubility of 90 mg/L, whereas other nickel compounds, such as nickel oxide, nickel sulphide and nickel tetra carbonyl are water insoluble.

Why is nickel present in water? Nickel may be found in slate, sandstone, clay minerals and basalt.The cementation of nickel and cobalt has been carried out in acidic sulfate solutions. Highor middle-carbon ferromanganese, or iron powder was added to the solutions containing 2 g/l.
