mineral processing - Concentration | Britannica

mineral processing - mineral processing - Concentration: Concentration involves the separation of valuable minerals from the other raw materials received from the grinding mill. In large-scale operations this is accomplished by taking advantage of the different properties of the minerals to be separated. These properties can be colour (optical sorting), density (gravity separation), …

Semiconductor Technologies – Wafer Testing, Dicing and ...

Grinding and Dicing. Equally crucial to further the semiconductor roadmap are grinding and dicing (cutting) technologies. Like wafer testing, grinding and dicing systems are dominated by only 2 players – DISCO Corporation and Tokyo Seimitsu. In the 1960s, semiconductor silicon wafer was only 23mm in diameter, and 275 microns in thickness.

Wet grinding must be used if the particle size is less than 8m. The so-called wet grinding is to mix the nanometer powder with the appropriate solvent to make the appropriate material. In order to avoid the phenomenon of powder agglomeration in the grinding process, appropriate dispersant or additives should be added as grinding AIDS.

Silicon wafer thinning, the singulation process, and die ...

Since this process also uses the brittle mode, micro-cracks called chippings are generated on the front and rear sides of the wafer. As a countermeasure for this problem, dicing before grinding (DBG) process is also applied. In this process, as shown in Fig. 2, grooving (half-cut dicing) is performed from the front side before grinding.

Comminution - an overview | ScienceDirect Topics

Comminution. Comminution till is defined as a 'very dense till that appears to have been formed by abrasion of bedrock and the crushing of detritus dragged along underneath the ice, accompanied by a mixing process that results in the incorporation of rock powder produced by abrasion at the till–rock interface into the overlying glacial load' (Elson, 1988).
