the crushed ore is reclaimed from one of three 500t ore silos via three feeders and fed to the rod mill feed conveyor. the grinding circuit consists of a single line consisting of a 3.81m diameter by 4.87m long rod mill (900kw), and two 3.00m diameter by 4.10m long (600kw) primary ball mills and a vertimill (930kw).
the rods grind the ore by tumbling within the the mill, similar to the grinding balls in a ball mill. to prevent the conditions leading to rod charge tangling, the length to diameter ratio is maintained at 1.4 to 1.6. rod mills accept feed up to about 50 mm (2 in.) and produce a product in the size range of 3000 to 270 mm (4 to 35 mesh
a rod mill uses steel rods as the grinding media in tumbling mills is an efficient means to feed ball mills a product finer than could be made in a crusher but coarser than could be made in a ball mill. the principal use for rod mills, which were invented to make ball mill feed in a wet-grinding rod mill-ball mill circuit. rod mills came into use in the united states beginning in 1900s and
apr 20, 2016 the crushed ore after automatic sampling is subjected to two-stage grinding using a rod mill in open circuit and a ball mill in closed circuit with a classifier. the unit flotation cell receives the discharge from the ball mill for recovery of a substantial amount of the granular silver minerals together with galena as soon as freed.
as the ore is ground into smaller particles it is mixed with water to form slurry. this slurry is then placed into a rod mill, which breaks the ore into even smaller pieces. once this process is finished, the slurry is run through a ball mill. the ball mill produces finely ground ore that consists of particles that have a diameter of roughly 0
uranium leaching is the process by which the uranium is extracted from the raw ore by reacting the material with acid or base. fig. 2 shows a general process flow for the uranium extraction process. prior to the leaching process, the ore is often given preliminary treatments that can include roasting and grinding.
