design of primary samplers for slurries in concentratorsat a typical concentrator plant, runofmine ore is fed through a crushing plant and mills or to autogenous mills to produce an ore feed slurry. it is generally accepted that the best sample of the head grade is the sample of the ore feed slurry because the ore is well mixed and the particle size is reduced. sampling of the runofmine ore or of a crushedus0907324a1 robot system and method for maxibagsat present, the molybdenum sampling process in maxibags is carried out manually and it has the disadvantage of being carried out manually which causes the system efficiency to decrease due to the less representativeness of the samples obtained. due to the above, a robot system and method have been developed for the sample taking of molybdenum in an automatic way so as to ensure thekennedy kereke process plant superintendent democratic©evaluate current and potential processing methods.
