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

Direct Nickel Home The DNI Process™

The unique features of the DNi Process™ The DNi Process™ uses nitric acid to dissolve and recover any saleable metal found in lateritic ores, tailings and waste material from other processes including, potentially, slag produced by ferro-nickel plants.. The unique and patent-protected aspect of the DNi Process™ is that 95% of the nitric acid is recycled (with 5%

Laterite nickel processing smelting methods and processes are as follows: Laterite Nickel Rotary Kiln. The preprocessing step is the raw material of nickel laterite ground with carbon material and flux limestone mixed, and then continuously input laterite nickel ore by rotary kiln. In the rotary kiln, the flow of hot gas from the combustion of the material and the coal is

Nickel Laterites: The World's Largest Source of Nickel

12/06/2014· Nickel is found in two types of deposits; Nickel laterites and magmatic sulfide deposits.Although nickel Laterites make up 70% of the world’s nickel reserves, few of them become producing mines. Over the last 60 years magmatic sulfide nickel deposits produced 60% of the world’s nickel.

Nickel laterite processing technologies where to next

Abstract. A review has been completed of current and proposed processing technologies for nickel laterite ores. Although future supplies of nickel depend on laterite ores, their processing is inherently energy intensive and expensive as, unlike sulphide ores, they cannot be significantly upgraded, meaning the entire ore needs to be treated in the process.
