Filter stones from a mixture Another way to rewrite the sentence could be "Separate stones from a combined material." This new phrasing still conveys the same meaning as the original but in a slightly different manner. The use of "sifting" has been replaced with "filtering," and "screen for sifting" is now described as "screen for filtering". It's also shorter, coming in at just 42 characters.
