What is the purpose of metallographic sample preparation treatments? Proper preparation of metallographic specimens is a key step to determine the accurate microstructure of a material and often requires sectioning, mounting, course grinding, fine grinding, polishing, etching and microscopic examination.

The principle purposes of grinding are: i. To obtain the correct degree of liberation in mineral processing. ii. To increase the specific surface area of the valuable minerals for hydrometallurgical treatment; i.e. leaching.

Conical burr grinders, like the ubiquitous Mazzer Robur E and Compak K10, have been the industry standard for years. As the name implies, conical burrs are cone-shaped, with a male and piece. This allows more efficient, faster grinding than with flat burrs. Conical burr grinders produce what is called a bimodal particle size distribution.

The purpose of grinding is to remove the deformation and possible thermal damage introduced during sectioning and to prepare the samples for polishing. Plane grinding, the first step, must produce a uniform finish and get all samples in a sample holder to the same level in a short time.
