Proverbs 25:4 New English Translation

⁴Remove the dross from the silver,
and material^[a] for the silversmith will emerge;

Proverbs 25:4 tn The Hebrew כֶּלִי (keli) means “vessel; utensil” (cf. KJV, ASV, NASB). But purging dross from silver does not produce a “vessel” for the silversmith. Some versions therefore render it “material” (e.g., NIV, NRSV). The LXX says “that it will be entirely pure.” So D. W. Thomas reads כָּלִיל (kalil) and translates it “purified completely” (“Notes on Some Passages in the Book of Proverbs,” VT 15 [1965]: 271-79; cf. NAB). W. McKane simply rearranges the line to say that the smith can produce a work of art (Proverbs [OTL], 580; cf. TEV “a thing of beauty”). The easiest explanation is that “vessel” is a metonymy of effect, “vessel” put for the material that goes into making it (such metonymies occur fairly often in Psalms and Proverbs).
