Nickel processing Extraction and refining Britannica

Nickel processing Nickel processing Extraction and refining: The extraction of nickel from ore follows much the same route as copper, and indeed, in a number of cases, similar processes and equipment are used. The major differences in equipment are the use of higher-temperature refractories and the increased cooling required to accommodate the higher operating temperatures in nickel

gas, etc.) as a reductant in a rotary kiln. Nickel and cobalt are firstly reduced because iron has The process is almost same as pig iron production processes. The only difference is that the ore contains more nickel. The blast furnace products contain 2-10% of nickel. A new approach is usage of electric arc furnaces to reduce operational costs [1, 2, 4, 7, 12, 13]. In this study

Production of FeNi from high iron nickel ores

Production of FeNi from high iron nickel ores ERIK SVANA* ROALD YSTEB Abstract The paper deals with the operation of FeNi-Furnaces when smelting high grade FeNi from ores containing more than 20% Iron oxide. Principles of operation have been discussed and compared to the operation of furnaces pro-ducing low grade FeNi in the well known non-selective smelting process. FeNi-SMELTING The

Technical & Cost Comparison of Laterite Treatment

increasing demand especially,in China led to,nickel pig iron smelting operations that now appear to have been adversely affected by the current lower nickel price. Laterite deposits typically contain ore zones with significantly different mineralogy, so any particular process may be applicable to only a portion of a new resource. This paper is the third in a series examining the processing

Difficulties when smelting high iron limonite in an electric furnace are (a) controlled reduction of the iron and (b) in cases where the liquidus temperature of the slag is below that of the alloy, a high slag super heat to melt the alloy. In ESS furnace technology, these problems are solved by performing solid state iron and nickel reduction

Smelting Wikipedia

Smelting is a process of applying heat to ore in order to extract a base metal. It is a form of extractive metallurgy.It is used to extract many metals from their ores, including silver, iron, copper, and other base metals.Smelting uses heat and a chemical reducing agent to decompose the ore, driving off other elements as gases or slag and leaving the metal base behind.

01/05/1987· After the nickel oxide ore (blended with high-iron-content nickel ore) is dried with a rotary dryer and crushed with an impeller breaker, it is mixed with coal as a reductant and fed into the kiln. In the kiln, the ore is calcined and pre-reduced (Ni reduction ratio 80%, Fe reduction ratio 60% ), and then hot- charged at a temperature of about 1,000 into the 60,000 KVA closed electric smelting

An alternative process route mixing Decar concentrates with saprolite ore at a pre-smelting, kiln reduction stage also gave positive results, but these are preliminary in nature. These bench-scale results indicate the potential amenability of Decar’s awaruite concentrate to downstream processing using conventional smelting technologies. This represented an important step towards introduction

Smelting of leaner ores for the production of Fe-Ni is possible technically but the energy consumption should increase considerably. This can be counteracted to some extent by an increase in the iron reduction (up to the limits of the ore iron content), but
