Is it possible to refine 100 pure metal?

Hello! At present, from a certain point of view, it can only be said that a certain substance can be detected by instruments, not pure or impure. There is no absolute purity, as long as it cannot be detected by sophisticated instruments, or its impurity content does not affect the use or interfere with it, we consider it pure.

Mine, are you still satisfied?

Puremetal

Metals that have undergone conventional or special refining to remove impurities are also called fine metals. Theoretically, pure metals should be pure and free of impurities, with a constant melting point and crystal structure. However, no metal can achieve absolute purity free of impurities, so pure metal only has a relative meaning, it only indicates the standard that has been technically achieved.

The classification can be divided into industrial pure metals and ultra-pure metals according to the impurity content. In production practice, the percentage purity of some industrially pure commonly used non-ferrous metals is: zinc, lead, tin, nickel, aluminum, etc.

Ultrapure metals contain impurities in the order of a few parts per million or more than the main metal, while ultrapure semiconductor materials have impurities in the order of a few parts per billion.

That is to say, there is no 100% pure metal, but the purity is relatively high, and it can be considered as a pure metal, such as 24k gold, which is called pure gold.

Hope it helps, satisfied, dear! If you have any questions, feel free to ask!

Summary. Hello, that scrap metal can't be refined into rhodium metal. Rhodium is extracted from primary ore, and the traditional method is preliminary enrichment by flotation, which is generally enriched to hundreds of grams to kilograms and thousands of grams.

After that, the matte is melted by the method of fire method, and then the acid is broken and dissolved to dissolve impurities, so that the rhodium is further enriched to tens of thousands of grams and even up to 20% of the content, and then melted with sodium bisulfate, and the water dissolves after the frit is cooled, and the rhodium enters the solution in the form of rhodium sulfate salt, and then transforms into rhodium hydroxide precipitation. The acid is filtered out to dissolve and discharge impurities, the nitrous acid is combined with the precipitation method to separate the rhodium salt, and the hydrogen is reduced to obtain rhodium powder. This method is still being applied by the domestic Jinchuan platinum industry.

Can that scrap metal be refined into rhodium metal?

Hello Mu staring at that kind of scrap metal can't be refined into rhodium metal. Rhodium is extracted from primary ore, and the traditional method is preliminary enrichment by flotation, which is generally enriched to hundreds of grams to kilograms and thousands of grams. After the first Qing Nai, the matte was melted by the method of fire method, and then the acid was broken and dissolved to dissolve the impurities, so that the rhodium was further enriched to tens of thousands of grams and even up to 20% of the content, and then melted with sodium bisulfate, and the water dissolved after the frit cooled, and the rhodium entered the solution in the form of rhodium sulfate salt, and then converted into rhodium hydroxide precipitation.

Abstract This paper uses a method of separating and purifying rhodium, especially separating and purifying rhodium from the heaching solution of rhodium-containing secondary resource waste. The technical characteristics of this method are that by adding a specially formulated triethylenetetraamine solution to the rhodium-containing solution, the rhodium in the solution generates a precipitate, and other precious and base metals will not react with the prepared triethylenetetraamine solution, so as to achieve the purpose of separating rhodium from other metals. The specific technical scheme is:

1) Adjust the concentration: adjust the concentration of rhodium ions in the rhodium-containing solution to g l; (2) Adjust pH: adjust the pH of the rhodium solution with the adjusted concentration to; 3) Heating rhodium:

The prepared triethylenetetramine solution was added to the rhodium solution with adjusted pH, and the rhodium precipitate was generated; (4) Filtration washing; (5) calcination; (6) Hydrogen reduction: put the calcined solid into the hydrogen reduction furnace, and the rhodium powder obtained by hydrogen reduction is 98%. The present invention is suitable for a wide range of materials, the process flow is short, the operation is simple, the production cost is low, and it is easy to realize industrialization.

How to refine rhodium metal.

Hello, I have seen your question and am sorting out the answer, please wait a while Have you refined it?

Rhodium was developed by the British chemist Wilam. Discovered by William Hyde Wollaston in 1803. He discovered rhodium soon after the discovery of palladium.

Walras first dissolved crude platinum in aqua regia, then neutralized the excess acid with caustic nanooh, and deposited platinum containing ammonium chloride and palladium containing mercury cyanide from the neutralization solution, and then treated the filter residue with hydrochloric acid to dry it thoroughly to avoid excess mercury cyanide. The alcohol-treated residue is a dark red powder of rhodium and sodium salts, which is produced without heating in a stream of hydrogen gas. Rhodium is obtained from a by-product of nickel production.

It can also be found in platinum ore and used as a catalyst in some platinum alloys.

I haven't refined it.

I've seen it all.

How to dispense triethylenetetramine?

Have you tried it the way he did.

Like what? I've tried it many times, but I don't remember specifically.

Rhodium is not sold, why do you have to refine it yourself.

There are lithium, rubidium, cesium, beryllium, titanium, zirconium, hafnium, vanadium, niobium, tantalum, molybdenum, tungsten, gallium, indium, thallium, germanium, rhenium, selenium, tellurium, scandium, yttrium, lanthanides, francium, radium, polonium, actinides, thorium, prometicum, actinides in actinides and 104 radioactive metals to element 107.

Rare metals are mainly used in the manufacture of special steel, cemented carbide and high-temperature alloys, in the electrical industry, chemical industry, ceramic industry, atomic energy industry and rocket technology. With the extensive study of rare metals, the discovery of new sources and new refining methods and the expansion of their application range, the boundaries between rare metals and other metals will gradually disappear, such as rare metals in the earth's crust more than copper, mercury, cadmium and other metals.

Some rare metals are similar in physico-chemical properties and are not easily separated into a single metal. In the past, it was made and used very little, hence the name rare metal. In the 19th century, the term "rare elements" existed, and in the 20s of the 20th century, it was named rare metals.

Rare metals were developed relatively late, so they are sometimes referred to as new metals. Since the Second World War, due to the development of new technologies, the increase in demand, the rapid development of rare metal research and application, the emergence of new metallurgical processes, the production of these metals has gradually increased. Rare metals are no longer rare.

The metals included in rare metals are also changing, such as titanium, which is increasingly widely used in modern technology and is produced in more abundant quantities, so it is sometimes included as a light metal. 

Existing metal here. No extraction, easy. Because the rare metals themselves are present in small quantities.

It's not the same thing.

Purification refers to the use of chemical or physical methods to purify a compound or mixture, or to extract what is desired from it. Smelting is a refining technology used for roasting, smelting, electrolysis and the use of chemicals to extract metals from ores. Reduce the impurities contained in the metal or increase a certain component in the metal to make the desired metal.

Smelting: yěliàn Meaning: to extract metals from ores by roasting, smelting, electrolysis and the use of chemicals; Reduce the impurities contained in the metal or increase a certain component in the metal to make the desired metal.

The people who wrote these answers seem to be half-understood.

Purification is the separation of impurities from a mixture to improve its purity; Smelting is a refining technology, which refers to the extraction of metals from ores by roasting, smelting, electrolysis and the use of chemical agents; Reduce the impurities contained in the metal or increase a certain component in the metal to make the desired metal. So it's not the same thing.
