Extraction of rhodium from rhodium oxide

1. Conversion to rhodium chloride

Usually, rhodium oxide is the starting point (Rh2O3). Rhodium must first be transformed into a more soluble rhodium compound in order to be extracted. Rhodium chloride (RhCl3) is typically produced by reacting it with hydrochloric acid (HCl).

2. Purification

Other metals and other contaminants could be present in the rhodium chloride solution that was prepared in the preceding step. Rhodium must be purified in order to be isolated from these contaminants. There are several chemical and separation methods that can be applied, including solvent extraction and precipitation.

3. Reduction

To produce metallic rhodium, a reduction procedure is applied to the rhodium chloride solution following purification. High temperatures and a reducing agent, like hydrogen gas (H2), are frequently used to accomplish the reduction.

4. Smelting

There's a chance that the reduction step's metallic rhodium has some other metal traces in it. Smelting is the process of removing impurities from metal by heating it to high temperatures. After that, the rhodium is usually melted and cast into the required shape, like bars or pellets.

5. Further refining

To reach a high level of purity, the extracted rhodium may go through additional refining procedures such zone refining or electron beam melting, depending on the requirements for purity. This is especially crucial if rhodium is going to be used in specific applications, such as the jewelry or electronics sectors.

Frequently asked Question

Why is jewelry rhodium plated?

Compared to platinum, white gold, or sterling silver, rhodium plating provides a brighter white and gives an additional layer of protection to jewelry. Realistically, rhodium is brittle and cannot be used to make solid jewelry because of its strength. To prevent cracking, a layer of rhodium plating needs to be precisely the proper thickness—between 0.75 and 1.0 microns is ideal. Any thinner and the metal underneath would show; any thicker and the coating would crack. Your jewelry can look better, last longer, and have a flawless covering of rhodium.

Fact about Rhodium

William Hyde Wollaston, who also discovered palladium, made the discovery of rhodium in 1803 while conducting experiments in South America with platinum ores. The rosy tinge of one of rhodium's chlorine compounds, which resulted from its interaction with aqua regia, inspired him to name the metal.

How is Rhodium recycledfrom a spent electroplating solution

1. Precipitation

The first step in recycling rhodium from used electroplating solutions is to separate it from other metals. This can be accomplished through precipitation using a base such as sodium carbonate.

2. Ion exchange resin

Rhodium can be separated as chloro salts by passing a solution containing both metals through a column of anion-exchange resin.

3. Solvent extraction

Solvent extraction is the process by which a chemical move from one solvent to another due to a difference in solubility or distribution coefficient between two immiscible (or marginally soluble) solvents.

4. Electrochemical Process

Rhodium electrowinning utilizing a modified electrochemical cyclone reactor has the potential to efficiently extract valuable metals from dilute solutions.
