You could sift the mixture through a wire screen sieve which has a mesh small enough to let the sand pass through, leaving the copper on top of the screen.

One common method to separate copper from sand dust is to use a technique called "gravity separation." This involves pouring the mixture into a container of water and allowing the copper, being denser than the sand, to sink to the bottom. The sand dust can then be poured off, leaving the copper behind. Another method is to use a magnet to attract and separate any magnetic particles of copper from the sand dust.
To separate a mixture of copper sulfate and sand, you can use the method of filtration. First, dissolve the copper sulfate in water to form a solution. Then, pour the solution through a filter paper to separate the sand from the copper sulfate solution. The sand will be left behind on the filter paper while the copper sulfate solution passes through.
You can separate sand and copper carbonate by using a process called filtration. First, mix the sand and copper carbonate in water to form a mixture. Then, pour the mixture through a filter paper in a funnel. The sand will be trapped on the filter paper while the copper carbonate will pass through as a liquid.
To obtain copper sulfate crystals from a mixture with sand, you can dissolve the mixture in water. The copper sulfate will dissolve, while the sand will not. You can then filter the solution to separate the sand from the copper sulfate solution. By evaporating the water from the copper sulfate solution, you can obtain copper sulfate crystals.
Add water to the mixture to dissolve the copper sulfate. Filter the mixture to separate the sand from the copper sulfate solution. Evaporate the water from the solution to recover the copper sulfate.
To separate sand and copper sulfate, you can add water to the mixture to dissolve the copper sulfate. Then, filter the solution to separate the sand. Finally, evaporate the water from the filtered solution to obtain the copper sulfate crystals in a dry state.
