1. JV is a method for separating a mixture of CARBONYLS of Nickel and iron, including rectification by evaporation of the mixture at a temperature above 42-43°C with the introduction of carbon dioxide, wherein the carbon dioxide is injected in an amount of 5 to 40% by volume vapor partial CARBONYLS.

Distillation is the process of separating the components or substances from a liquid mixture by selective boiling and condensation. This method is best for separating a liquid from a solution. In a way, the concept is similar to evaporation, but in this case, the vapor is collected by condensation.

2016-11-17 Here's a phase diagram for a copper-nickel alloy, which I think is a system where both components are completely soluble in one another in all ratios. This composition cannot be separated by cooling it down, as I understand it (even though, as mentioned here, the composition would not be uniform if the molten alloy is not cooled down slowly enough

2006-10-1 From Table 1, it can be seen that our developed method offers some advantages in separation of Cu radioisotopes from a nickel target.In the anion-exchange method, which has been used in practice, 61 Cu is gradually stripped out whenever the eluent (9 M HCl) is added into the column. The separation was inefficient, particularly when the initial radioactivity is at a high level.

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.

2016-11-17 $\begingroup$ Essentially, the phases formed from molten metals and molten salts (given that they mix at all, which is not always so) may be either "metal-like" or "salt-like". In the first case it would conduct electric current using electrons, much like electric wires in your house, and would be able to do so for years without any change.
