What is the refinement of precious metals?

The refinement of precious metals is a technique used to clean precious metals. There are several different methods for refining precious metals, but two main methods are pyrometallurgy, which includes heating and hydrometallurgia, which includes the dissolution of metals into a solvent. After cleaning, the metals are cleaned to complete the refining process. During the sampling, the metal is considered, measured and melted into the liquid and then samples are collected. The founding company usually maintains one sample and the customer is given the other. After sampling, a test is carried out to determine the exact amount and concentration of precious metals and dirt to be removed. During pyrometallurgy, it is metal and molten to separate different impurities. With some metal processing, the form of gas to the bubble will be used for the molten metal and oxids targeted precious metals or dirt, which changes consistency to allow removal. In some cases, dirt and expensive metals will melt at significantly different temperatures, allowing witha multiple separation by physical means.

A special type of pyrometallurgy, known as the refine of the zone, is an expensive but highly effective cleaning process. This technique of precious metal refining involves stretching metal to be cleaned into a long bar. The rod then heats them up, starting at one end and the dirt remains in liquid form and migrate on the lane when the next part warms them. At the end of the bar, the dirt is collected in the last segment, allowing easy removal. Process repeat it several times and create a loss of a significant part of the metal, but the rest of the metal leaves cleaning.

Hydrometallurgy is another main type of precious metal refining and includes the use of a solvent to dissolve the metal to remove dirt. The first step of this process is known as leaching, during which the metal is dissolved using a solvent known as Lixiviant, which is either acidic or basic. Furthermore is the PU solutionRicked processes of precipitation, extraction or ion. The last step is to restore precious metals from cleaned solution and technology for this step include precipitation, electrorefine and gas reduction. Hydrometallurgia is a much more variable process and a wide range of different methods allows it to be adapted for an individual sample to be refined.
