Guide to Modern Smelting Processes

• Metal Extraction: Smelting is the primary method for extracting metals from their ores. It allows for the separation of valuable metals from the host rock or mineral matrix in which they are naturally found. Commonly extracted metals include iron, copper, aluminum, lead, zinc, nickel, and precious metals like gold and silver.

Teck's CESL Nickel Process: Advancing Towards a …

Smelting and refining of massive sulphides begins with the flotation of ore, typically in the range of 0.2-2% nickel, to an acceptable concentrate grade of 10 to 20% nickel. Concentrate smelting produces a high grade nickel matte which is then refined hydrometallurgically. With the majority of the world's nickel supply coming via ...

One-Step Extraction of Nickel from Nickel Sulfide

The conventional nickel smelting and refining is the dominant strategy for nickel production from the sulfide nickel ores. The main disadvantages are the significant amount of SO 2 emissions during smelting and complex refining processes. In this paper, the authors investigated a solid-state nickel extraction method that recovered nickel …

CRI Indonesia Report: Nickel Unearthed

While there are multiple ways to refine nickel ore, conventional refining involves the grinding of ore into small particles, heating the materials in a rotary kiln, and extracting the metallic minerals through smelting. 39 E Keskinkilic, "Nickel Laterite Smelting Processes and Some Examples of Recent Possible Modifications to the …

Nickel

16,000 tons of nickel in concentrate, which was exported to smelters in Canada and overseas. A company in Missouri recovered metals, including nickel, from mine tailings as part of the Superfund Redevelopment Initiative. Nickel in crystalline sulfate was produced as a byproduct of smelting and refining platinum-group-metal ores mined in Montana.

12.11 Secondary Lead Processing

Refining and alloying operating temperatures range from 320 to 700°C (600 to 1300°F). Alloying furnaces simply melt and mix ingots of lead and alloy materials. Antimony, tin, arsenic, copper, and nickel are the most common alloying materials. Refining furnaces are used to either remove copper and antimony for soft lead production, or

Sudbury: Nickel Smelting and Refining
