As the refining process progresses, the servo system moves the nickel rod downward at a speed of 0.6 mm/min until the refining length reaches 75 mm, ensuring a consistent and stable molten zone. After four repetitions of the above refining process, the final high-purity nickel sample can then be analyzed for impurity content to assess the ...

Nickel Refining Processes. The most common method of refining nickel is electrolysis. In this process, nickel ore is dissolved in a compound called an electrolyte, which conducts electricity through a solution. An electric current is then passed through the solution, and the nickel ions are attracted to a cathode (positive electrode) and ...
