First, place the sulfur, sand and iron filings in a plastic container. Next, use a magnet to remove the iron filings from the sulfur-sand mixture and surely,the iron filings will connect to the magnet, leaving the sulfur and sand behind.

What is the process of swirling a mixture containing a valuable mineral to separate the mineral from the rest of the rocks?
It is known as panning, usually for gold nuggets, using a shallow metal pan.
Is gold chemically bonded or a mixture?
Gold is an element with the symbol Au, and therefore it is not a mixture. However, commercial gold is often mixed with other metals to help it maintain its shape while still looking like pure gold, because gold is very soft compared to other metals. So gold jewelry, unless it is made of 24 carat gold, is a mixture, not a compound, but pure, unaltered gold is not a mixture, but an element.
Is gold an heter or homo?
Gold is a chemical element not a mixture.
Is a gold nugget a homogenous mixture?
Gold is a pure substance
What is a mix of gold and silver called?
It is simply a mixture of gold and silver.
How would you separate gold dust from a mixture of iron filings and salt?
Mix with water, the pass through a filter paper. The salt will be dissolved in the water so it will be removed with the water, leaving the iron filings and gold dust on the filter paper. Leave this to dry then separate off the iron filings using a magnet, leaving behind the gold.
How would you separate gold from a mixture of gold and copper filings?
Add concentrated sulphuric acid to the mixture
How separate lead gold mixture to gold?

How could you separate gold from a mixture of zinc and gold?
We could add HCl to the mixture of Zinc and Gold and see which one appear to separate first.
What mixtures did prospectors have to separate during the gold rush?

How do separate gold from sodium gold chloride?
You can separate gold from sodium gold chloride by adding zinc powder to the sodium gold chloride and heating the mixture. Then you will be left with just gold.
What is a way to separate Salt White Sand Iron filings and Gold filings into four separate piles?
Use a magent to pick out the iron particles. Soak the remainder in water until the salt is dissolved - dry the water, leaving behind a pile of salt. Mix the rest with mercury - the gold clings to the mercury, leaving behind a pile of sand. Use cyanide to separate the gold out of the mercury and remove the mercury.
Is gold homogeneous or heterogeneous mixture?
Gold is a pure element, not a mixture of any kind.White gold (alloy with nickel, manganese, or palladium) is a homogeneous mixture because you can't see the separate substances that are in it. Therefore it is a homogeneous mixture.
How do you separate gold from a mixture of gold and zinc?
Since gold binds with zinc, you would have to chemically extract the gold out with aqua regis.
How do you separate a mixture of gold nuggets from iron filings and sodium?
The separation of gold from iron filings and sodium metal (a dangerous substance which will react with water in the air) could be done in two steps. Take a magnet and put it inside a plastic bag. Carefully and fully move the bagged magnet over the mixture, gently stirring it to insure the magnet can "reach" all the iron filings. When you are done, lift the magnet clear of the mixture, and you should have all the iron filings stuck to the magnet, which is inside the bag. If you carefully "invert" the bag, you'll then have the bag around the filings, which will still be stuck to the magnet with a layer of plastic bag between the two. Then just close the bag and remove the magnet. Your iron filings have been separated and bagged up. Now turn your attention to the gold and sodium mixture. Put them in a big heavy plastic container. If you *carefully* add water, you will get a chemical reaction. It is *critical* to put water in a drop at a time. (Yes, a drop at a time.) The sodium will react with the water and create sodium hydroxide, which is powerful base. It will also create a lot of heat, so you have to take all day to drop in the water so it won't melt your bucket. There will be some strong fumes, too, so take precautions. The bucket, because it is plastic, won't react with the sodium hydroxide. After you spend all day dripping the water into the mixture to react with all the sodium, you'll have a solution of sodium hydroxide with the gold in it. Strain this mixture and the gold will remain in the sieve. You'll need to wear a ton of protection to perform this evolution. Rinse your gold well to remove the traces of the sodium hydroxide and you're in business.
How do you separate the gold from a mixture of gold and iron powder and salt?
First add water to the mixture to dissolve the salt, then filter with filter paper to obtain the mixture of gold and iron. Proceed by using a strong enough magnet to extract the iron powder and you should be left with the Gold.....
How do you separate gold from a zinc-gold mixture?
Gold when put in aqua regia dissolves. Aqua regia is obtained by mixing concentrated nitric acid and concentrated hydrochloric acid.Once the gold is dissolved the metals are participated out by adding salts ( not table salt) to the mixture.
