Polishing A process using very fine abrasive minerals for little or no material removal where visual appearance is the primary purpose.
Traditionally, grinding to 80% passing 75um is regarded as "conventional" since many operations grind to that size. Regrinding is considered to produce the particles finer than 75um down to 30 lm. Fine grinding is a relatively new area and considers grinding below 30um down to around 10um. Below 10um, the term "very fine grinding" can be used.
