Grinding In Mineral Processing

basics of mineral processing,the two main purposes for a grinding process are: • to liberate individual minerals trapped in rock crystals (ores) and thereby open up for a subsequent enrichment in the form of separation. 11. 11 • to produce fines (or filler) from mineral fractions by increasing the specific surface. use of fine grinding in mineral processing,as polishing the mineral surface, which can enhance recovery. doi: 10.1007/s40553-013-0001-6 the minerals, metals & materials society and asm international 2013 i. introduction fine grinding is becoming an increasingly common unit operation in mineral processing. while fine grinding can liberate ores that would otherwise be considered.
