Tin in the slag as oxide was recovered by reduction using carbon or hydrogen gas at 650-700 degrees C. Different valuable chloride salts were also obtained in good quality. Further research is recommended on the thermodynamics of nickel-copper recovery, yttrium and europium recovery, and process economics.

used as feed for the converting process. The slag, varying in nickel content from 0.1 to 0.5 per cent, is tapped continuously and granulated in water. The slag granules are collected in rake classifiers, and later milled and floated in the slag plant to recover entrained matte, and hence reduce PGE (and base metal) losses. Sampling methodology During the initial campaign

The target of the current work is to investigate the possibility of nickel recovery from EAF slag by magnetic separation. To meet the target, the effect of the following parameters was studied: grain size, magnetic field intensity, thickness of slag layer, moisture

Reductive Smelting for the Recovery of Nickel in a DC Arc

slag, where the nickel is present either as entrained metallic particles or as dissolved oxides. If oxides are present, reductive smelting is used to get the nickel into the metallic form. One useful way of recovering the nickel is to collect it in an iron alloy. A DC arc furnace can be used very effectively for this purpose. Mintek has demonstrated this process on a number of furnaces,

Compositions of the modified slags (mixture of nickel slag and CaO) with different slag basicities (mass ratio of CaO/SiO 2 in slag system) were plotted in Fig. 3. 40) As shown in Figs. 3(a) and 3(b), CaO–FeO–SiO 2 –MgO and CaO–Al 2 O 3 –SiO 2 –MgO were the corresponding slag systems before and after the reduction process, respectively. Point A represented the composition of nickel

The reduction roasting ammonia leaching process (RRAL) originally defined by Caron (1950) has been extensively applied to treat low grade nickel laterite and a large amount of slag-containing some valuable metals, has been generated and accumulated over the years since then. However, there are no reports on how to utilize it based on its essential properties.

nickel, copper and cobalt. The process is based on well-known metallurgical unit operations like drying, selective reduction, smelting, oxidizing, sulfiding and converting. Valuable metals like nickel, copper and cobalt are concentrated in an early stage of the process by reduction into a metallic phase and manganese is mainly discarded in the manganese-silicate slag. Excess iron and
