Grinding (abrasive cutting) - Wikipedia

Grinding is a subset of cutting, as grinding is a true metal-cutting process. Each grain of abrasive functions as a microscopic single-point cutting edge (although of high negative rake angle), and shears a tiny chip that is analogous to what would conventionally be called a "cut" chip (turning, milling, drilling, tapping, etc.) [citation needed].

approach to take for fine grinding in metallurgy

Fine Grinding Before Leaching. Unlike flotation, leaching appliions do not suffer as much from the same surface chemistry impacts from steel media. The use of steel media, however, can still be detrimental to a leaching process. When fine grinding pyritic concentrates of precious metals, it is common to follow the fine
