Amount Of Feed To Rod Mill When Grinding Copper Ore

A rod mill is an ore grinding mechanism that uses a number of loose steel rods within a rotating drum to provide its attrition or grinding action an ore charge is added to the drum and as it rotates friction between the tumbling rods breaks the ore down into finer particles

Copper processing is a complicated process that begins with mining of the ore less than 1 copper and ends with sheets of 9999 pure copper called cathodes which will ultimately be made into products for everyday most common types of ore copper oxide and copper sulfide undergo two different processes hydrometallurgy and pyrometallurgy respectively due to the different

A rod mill is an ore grinding mechanism that uses a number of loose steel rods within a rotating drum to provide its attrition or grinding action an ore charge is added to the drum and as it rotates friction between the tumbling rods breaks the ore down into finer particles

During prolonged periods of crusher maintenance the ore walls can be bulldozed over the ore feeders to provide an uninterrupted supply of ore for milling grinding copper ore as it is shown in this study the or 1 crushed ore is fed to a rod mill operating in open circuit and discharging a product approximately minus 14mesh

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 14 to 16 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

Measuring ore grindability in rod mills the bond rod mill work index is a measure of the resistance of the material to grinding in a rod mill it can be used to determine the grinding power required for a given throughput of material under rod mill grinding conditions it is a locked cycle test conducted in closed circuit with a laboratory

Jaw and gyratory crushers are used for initial size reduction to convert big rocks into small stones this is generally followed by a cone crusher a combination of rod mill and ball mills are then used if the ore must be ground below 325 mesh 45 m instead of grinding the ore dry slurry is used as feed for rod or ball mills to avoid dusting
