Environmental Guidelines for Nickel Smelting and Refining

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: smelting, producing-Metalpedia

In hydrometallurgical processes, nickel sulfide ores undergo flotation (differential flotation if Ni/Fe ratio is too low) and then smelted. After producing the nickel matte, further processing is done via the Sherritt-Gordon process. First, copper is removed by adding hydrogen sulfide, leaving a concentrate of only cobalt and nickel.

What Is Nickel Smelting? (with picture)

Feb 13, 2021 The next process in nickel smelting is refining the liquid matte, which is typically done with one of two processes. With fluid bed roasting, sulfides are added to the liquid matte and the two are roasted together, eventually leaving just the nickel metal.

Nickel element extraction, mining technique flash

The concentrate of nickel obtained is then leached with either sulphuric acid or ammonia, dried and smelted similarly like copper. Higher smelting temperatures are required in the case of nickel to produce an artificial nickel-iron sulfide known as matte, composed of 25 to 45 percent nickel.

How clean can the nickel industry become? McKinsey

Sep 11, 2020 The unavoidable impacts of mining, smelting, and refining Class 1 nickel Leaving aside the impending shortage of Class 1 nickel, mining inevitably has an impact on an asset’s surroundings. The International Council on Mining and Metals (ICMM) has defined a set of Mining Principles aimed at maximizing the benefits to local communities, while

Proposed regulation for the nickel smelting and refining

Jan 20, 2021 Two nickel smelting and refining companies located in Sudbury, Glencore and Vale, have made significant investments in technology to reduce sulphur dioxide emissions at their facilities in order to meet requirements set out in ministry approved site-specific standards. These investments have resulted in: reduced sulphur dioxide emissions, and

Nickel: smelting, producing-Metalpedia

Nickel: smelting; Extraction and purification; Nickel is recovered through extractive metallurgy: it is extracted from its ores by conventional roasting and reduction processes that yield a metal of greater than 75% purity. In many stainless steel applications, 75% pure nickel can be used without further purification, depending on the composition of the impurities.

Nickel Glencore

It produces two concentrate streams: nickel-copper concentrate for smelting, and copper concentrate for smelting and refining. The Sudbury Smelter currently smelts nickel-copper concentrate and processes custom-feed materials in the form of concentrates and secondary products.

Hydromet Technology Vale

The nickel industry worldwide has traditionally smelted concentrates produced from nickel, copper and cobalt sulphide ores to make an intermediate sulphide product called matte. Hydrometallurgy has been used for refining the matte to produce high purity nickel, copper and cobalt for the market.

Cobalt extraction Wikipedia

Nickel-cobalt lateritic ores can be treated by either hydrometallurgical processes or pyrometallurgical processes, such as matte or ferronickel smelting, which require the entire ore to be melted and the metal values to be separated from the residual components of the ore. The hydrometallurgical process for laterite ore can use sulfuric acid or

Environmental Impacts of Nickel Mining and Processing

Nickel deposits are typically found in low-grade ores (~1-2% nickel) thus making it highly energy intensive to extract and refine the metal. This leads to high emissions of greenhouse gases into the atmosphere and the use of large amounts of energy derived predominantly from fossil fuels ( 2 ).

Lead processing Refining Britannica

The Parkes zinc-desilvering process is the most widely used pyrometallurgical method of refining lead bullion. As in smelting, the lead is first melted and again allowed to cool below the freezing point of copper, which crystallizes and, along with any remaining nickel, cobalt, and zinc, is removed by skimming. The lead mix then passes to a

Nickel smelting and refining: A long road ahead for Indonesia

May 13, 2015 When Indonesia placed export restrictions on nickel ore early last year, the plan was to encourage the country’s mining firms to develop their own smelting and processing facilities so that Indonesia could export refined ores and concentrates, which are worth more in the market than raw ones. More than a year later, Indonesia’s ban on ore exports is stimulating investment in processing
