Mineral processing Wikipedia

OverviewHistoryUnit operationsOther processesConferencesSee alsoNotesSources

Before the advent of heavy machinery the raw ore was broken up using hammers wielded by hand, a process called "spalling". Before long, mechanical means were found to achieve this. For instance, stamp mills were used in Samarkand as early as 973. They were also in use in medieval Persia. By the 11th century, stamp mills were in widespread use throughout the medieval Islamic world, from Islamic Spain and North Africa in the west to Central Asia in the east. A later example was the Cornish stamps, consisting oget price

Gravity Seperation Method Concentration Of Ore

Physical separation processes, including blasting techniques, ore sorting, screening, magnetic separation, gravity separation, jigs, may be employed as pre-concentration techniques.
