The improvements in SAG milling efficiency with a pebble crusher for some ores are now well established. In Australia, these were pioneered at Argyle on diamond ores and proved problematic.
The application of DMS preconcentration, and its success, is very site- and ore-specific. DMS can be implemented on greenfield projects or be considered for brownfield expansions. On brownfield projects, a DMS and crushing circuit is typically installed between the primary crusher and primary mill.
The first step in turning ore into useful minerals starts with making the ore smaller by crushing and grinding it under high pressure. Machines called jaw crushers and gyratory crushers are super important …
When buildup of these materials does occur, pebble crushing can improve mill throughput even more dramatically than when the critically sized fraction results purely from a breakage rate deficit alone. For these ore types, a pebble-crushing circuit is an imperative for efficient circuit operation.

The ball mill is a rotating cylindrical vessel with grinding media inside, which is responsible for breaking the ore particles. Grinding media play an important role in the comminution of mineral ores in these mills. This work reviews the application of balls in mineral processing as a function of the materials used to manufacture them and the …
Results from test work from platinum ore on HPGR Test work has been conducted on two South African platinum ores. One being a Platreef ore, a sample of which consisted of pebbles from an AG circuit. The second one consisted of a UG2 ore obtained from a crushing plant feeding a rod and a ball mill. Both samples were treated on

Relation of Bond rod mill work index and crushing work index. Similar to the ball mill work index, the rod mill work index is a tumbling test that includes both attrition and abrasion breakage mechanisms. Unlike the ball mill work index, the size of the feed to a rod mill test (10 mm–12 mm) is closer to the size of the crushing test.
Copper processing is a complicated process that begins with mining of the ore (less than 1% copper) and ends with sheets of 99.99% pure copper called cathodes, which will ultimately be made into products for everyday use.The most common types of ore, copper oxide and copper sulfide, undergo two different processes, hydrometallurgy and …
