How is platinum disposed?
Platinum, along with the rest of the platinum metals, is obtained commercially as a by-product from nickel and copper mining and processing. During electrorefining of copper, noble metals such as silver, gold and the platinum group metals as well as selenium and tellurium settle to the bottom of the cell as "anode mud", which forms the starting point for the extraction of the platinum group metals.[42]If pure platinum is found in placer deposits or other ores, it is isolated from them by various methods of subtracting impurities. Because platinum is significantly denser than many of its impurities, the lighter impurities can be removed by simply floating them away in a liquid. Platinum is also nonmagnetic, while nickel and iron are both magnetic. These two impurities are thus removed by running an electromagnet over the mixture. Because platinum has a higher melting point than most other substances, many impurities can be burned or melted away without melting the platinum. Finally, platinum is resistant to hydrochloric and sulfuric acids, while other substances are readily attacked by them. Metal impurities can be removed by stirring the mixture in either of the two acids and recovering the remaining platinum.[43]One suitable method for purification for the raw platinum, which contains platinum, gold, and the other platinum group metals, is to process it with aqua regia, in which palladium, gold and platinum are dissolved, while osmium, iridium, ruthenium and rhodium stay unreacted. The gold is precipitated by the addition of iron(III) chloride and after filtering off the gold, the platinum is precipitated as ammonium chloroplatinate by the addition of ammonium chloride. Ammonium chloroplatinate can be converted to the metal by heating.[44] Unprecipitated hexachloroplatinate(IV) may be reduced with elemental zinc, and a similar method is suitable for small scale recovery of platinum from laboratory residues.[45]
Is acetate can be recycled?
Yes, acetate can be recycled. Acetate products, such as clothing and packaging materials, can be recycled through specific recycling facilities that are equipped to handle this type of material. Recycling acetate helps reduce waste and lessen the environmental impact of its production.
What is the 3 most commonly recycled metal?
The three most commonly recycled metals are aluminum, steel, and copper. Aluminum is the most recycled metal because it does not degrade during the recycling process and can be recycled indefinitely. Steel and copper are also commonly recycled due to their high demand and the cost savings associated with recycling them.
What happens to glass bottles?
Glass bottles can be recycled by melting them down and forming them into new bottles or other glass products. If not recycled, they can take thousands of years to decompose in a landfill, contributing to environmental problems. Glass bottles that are not recycled can be repurposed for various DIY projects or used for decoration.
What is the Latin name for pLatinum?
The Latin name for platinum is "Platinum." Its chemical symbol is Pt, and it has an atomic number of 78.
