A New Process for Co-Ni Separation – ALTA 2010 2 ABSTRACT A new process has been developed jointly by CSIRO and CESL, for separating cobalt from nickel in an impure leach solution. The process uses synergistic solvent extraction (SSX) with commercially available reagents, but in a novel and efficient manner using kinetic factors.
process. This addition of sulphur will favor the transformation of nickel, copper and cobalt oxides into sulphides and at the same time will lower the melting temperature of the matte to less than 1300 ºC from the 1400 ºC of the nickel iron alloys [8-9, 16 ]. 2. experimental Converter slag .
Outotec Slag Cleaning Slag cleaning at copper and nickel smelters is typically done using an electric furnace process. The design of Outotec slag cleaning furnaces is based on our extensive experience with different slag compositions and under-standing of how to optimize the process for maximum recovery.
A hydrometallurgical process for the recovery of nickel and cobalt values from a sulfidic flotation concentrate. The process involves forming a slurry of the sulfidic flotation concentrate in an acid solution, and subjecting the slurried flotation concentrate to a chlorine leach at atmospheric pressure followed by an oxidative pressure leach.
With the increased requests for more sustainable extraction processes feedstocks with low metal content are becoming more attractive. In this research, an additional refining step is investigated in order to recover valuable metals from slag generated during nickel extraction process, particularly copper, nickel, and cobalt.
Abstract. Nickel slag can be recycled as one of the excellent secondary sources due to valuable iron resource. Slag viscosity during iron recovery from nickel slag by aluminum dross was studied from 1773 to 1873 K, and the viscosity evolution in different periods was systemically discussed.
OUTOTEC SMELTING SOLUTIONS FOR THE PGM INDUSTRY L. Aspola Outotec R. Matusewicz Outotec K. Haavanlammi Outotec ... As in any extraction process, recovery of the metals is crucial. Fortunately there is little tendency for the ... Figure 4-Nickel smelting slag target chemistry
Nov 14, 2012· During the recovery of base metals from the Bushveld Igneous Complex ores, South Africa, a two-stage process is used to ensure complete recovery of nickel from the ore. A nickel flash smelting furnace is initially used to obtain the valuable metal but the loss of nickel in the slag amounts to about 4 % and thus an electric slag-cleaning furnace has to be subsequently used to reduce the loss .
Described here is a process for recovering chromium and other metals from superalloy scrap. Laboratory-scale experiments were conducted to test a complex flowsheet utilizing a wide range of extractive metallurgical operations.
attention in the utilization of nickel slag. This study involves the selective recovery of non-ferrous metals (nickel and copper) versus iron, from nickel slag by selective reduction−magnetic separation process, with an aim to make high-grade nickel and copper concentrate for producing special steel, i.e.
The method of removal of chromium and/or Nickel from a liquid slag or mixtures thereof, including the supply of liquid slag containing chromium and/or Nickel, in a liquid metal bath, in particular iron-containing bath, and recovering the liquid slag in two stages, with the first stage of recovery is carried out by introducing carbon or media ...
Meanwhile, an economically viable extraction process was proposed to preliminarily utilize the nickel slag based on textural and mineralogical characteristics of the slag, and the magnetic concentrate, assaying about 62% iron grade at over 75% recovery rate, was obtained through the recommended method.

streams of some process effluents to prevent a build-up of various impurities. Solid wastes from nickel sulfide ores often contain other metals such as copper, and precious metals, and consideration should be given to further processing for their recovery. Slag can be used as construction material after nickel recovery .
During the pyrometallurgical treatment of the nickel-bearing laterite in the plant of G.M.M. S.A. LARCO, slag is produced after treatment in electric-arc furnace (EAF) that contains 0.10 to 0.20 % Ni. Taking into account the great quantity of slag produced per year, the recovery of nickel from the EAF slag will add benefits to the entire process.
Slag/dross and leaching residue are produced from the process of metal extraction. The commonly-seen slag/dross/residue includes copper dross, lead dross, tin slag, zinc leaching residue, antimony/arsenic dross, cadmium residue/cake, sulfur residue/cake, vanadium slag, nickel slag, iron tailing and iron bearing red-mud waste.
Slag/dross and leaching residue are produced from the process of metal extraction. The commonly-seen slag/dross/residue includes copper dross, lead dross, tin slag, zinc leaching residue, antimony/arsenic dross, cadmium residue/cake, sulfur residue/cake, vanadium slag, nickel slag, iron tailing and iron bearing red-mud waste.
Sep 29, 2017· A generalized flow sheet of the recovery of copper, cobalt, and nickel can be found below, Figure 1. Fig. 1: Generalized Flow Sheet of Copper/Cobalt/Nickel Recovery (Fisher, 2011) When designing processes for cobalt recovery, it is important to analyze and overcome some of the technical challenges that lie ahead.
In order to utilize slag discarded by nickel plants, the selective recovery of nickel and copper versus iron was investigated by selective reduction, which was achieved by controlling the reduction parameters and magnetic separation process on bench scale.
During the pyrometallurgical treatment of the nickel-bearing laterite in the plant of G.M.M. S.A. LARCO, slag is produced after treatment in electric-arc furnace (EAF) that contains 0.10 to 0.20 % Ni.
For those working in the nickel waste recovery industry, there is an understanding of just how difficult and costly the process can be. The treatment process that allows nickel to be recovered from waste materials includes filtration and then a drying process, before anything can be done with it at all.
The ability to fire assay a substance relies on a number of facts. First of all, the samples that contain gold and silver should be solubility in molten metallic lead and that gold and silver are insolubility in slag. Fire assay also relies on the difference in specific gravity between the two liquids, the molten lead and the slag.
method. In addition to the recovery of valuable metals, the slag product of the process, known as Plasmarok®, can be sold for use as an aggregate, owing to its inertness, low leachability and engineering properties. The exhaust gases pass into a secondary combustion chamber to .
