Pyrometallurgical processing of nickel sulfide ores is very close to the other base metals and includes roasting, smelting and converting [10]. Depending on the grade of ores, copper is obtained as an important byproduct or coproduct. Sulfide ores are mined by either opencut or underground mining.
Dec 01, 2017· Nickel Smelting This guide will cover the process of obtaining Nickel Ingots from Nickel Ore. There are three tiers of smelting for nickel. The first tier has a 1:1 input to output ratio, so it will not be covered by this guide. The second tier multiplies input by, and the third tier multiplies input by 2.
Nickel requires higher smelting temperatures (in the range of 1,350 °C [2,460 °F]) in order to produce an artificial nickeliron sulfide known as matte, which contains 25 to 45 percent nickel. In the next step, iron in the matte is converted to an oxide, which combines with a silica flux to form a slag.

Nickel is primarily sold for first use as refined metal (cathode, powder, briquet, etc.) or ferronickel. About 65% of the nickel consumed in the Western World is used to make austenitic stainless steel.
Nickel pig iron (NPI) production has been experiencing robust development recently in China. For NPI production by smelting technology in either a blast furnace or an electric arc furnace, sintering is imperative to supply a qualified feedstock.
lateritic nickel ore BF smelting process has the following technical characteristics different from that of conventional iron ore BF smelting process. Sintering process of lateritic nickel ore Water in the surface of lateritic nickel ore is as high as 20%, and crystal water content is usually about 15%.
Outotec® Direct Nickel Process Get continuous production of highgrade nickel matte with low iron content with the Direct Outotec Nickel Flash Smelting Process. When coupled with our slag cleaning process, nickel smelting is straightforward, cost effective, and .
• Nickel and Cobalt. • Carbon and Graphite. Carbon and graphite production was also included as a separate group as many such processes are associated with primary aluminium smelters. Processes for roasting and sintering of ores and concentrates and for the production of alumina were also included within these groups where applicable.
436 Nickel Smelting and Refining cathodes is the most common technology used for nickel refining. Electrowinning, where nickel is removed form solution in cells equipped with inert anodes is the more common refining process used for nickel. Chloride electrolytes are used although sulfuric acid solutions are used more often. Waste Characteristics
Nickel increases the density of sintered compacts made with elemental nickel powders. Carbon content dictates the maximum strength attainable in P/M steels, either assintered, or when heat treated after sintering. Alloy additions enhance the ability to achieve high strength with useful ductility and fracture resistance. Nickel contributes most
Nickel Smelting, Nickel Smelting Suppliers and . The smelting of nickel pig iron mainly use submerged arc furnace and blast furnace, usually the arc furnace produces high grade nickel, and blast furnace produces medium and low grade nickel iron. Otherwise, the cooling water for blast furnace can be recycled by building a closed cooling water pool.
The invention relates to a bessemer matte production method using nickel sulfide materials which comprises, oxidizing and sintering nickel sulfide as main raw material, mixing with fusing agent, fluxing agent and reducing agent, smelting at deg C, holding the temperature for reacting 3060min, thus obtaining Bessemer matte product.

Sintering process of lateritic nickel ore Water in the surface of lateritic nickel ore is as high as 20%, and crystal water content is usually about 15%.
FURNACE OPERATION. The carbonaceous reducing agent is added in such quantities that the oxygen in the offgases is substantially in the form of carbon monoxide, and the nickel content of the slag is below %. The temperature of the furnace is controlled to between 1500 .
Zinc: smelting; Zinc Mining; 80% of zinc mines are underground, 8% are of the open pit type and the remainder is a combination of both. However, in terms of production volume, open pit mines account for as much as 15%, underground mines produce 64% and 21% of mine production comes from the combined underground and open pit mining.
The production of powder metal components can be summarized in three steps: powder preparation, compaction and sintering. Metal powder is first formed and blended to a desired chemical composition. During this step, a lubricant, such as wax, is added to help .
