Study on Sumbawa gold ore liberation using rod mill ...
Comminution is one of crucial steps in gold ore processing used to liberate the valuable minerals from gaunge mineral. This research is done to find the particle size distribution of gold ore after it has been treated through the comminution process in a rod mill with various number of rod and rotational speed that will results in one optimum milling condition. For the initial step, Sumbawa ...

Copper in the USA: Copper Producers
In recent years, many producers have installed continuouscast rod mills to directly convert hode copper to wire rod (typically 5/16 inch in diameter), the feed material for the wire and cable mills. Primary producers may also convert the hode to cakes or billets of copper for sale to brass mills. The consumption of refined copper (mostly hodes) in the United States was about ...

Rock Crushers
When a rock has values in it, it's then called ore. In order to liberate the minerals, it needs to be crushed down. In days of yore, a stamp mill was the primary form of crushing rock, but in the modern world, there are jaw crushers, impact mills and gyrator crushers, as well as ball mills. They all have their own pros and cons and price ...

Rock Crushing methods and How to recover gold from Ores
A heavy cylinder of iron is welded to a long rod and placed inside a pipe or tube which is just a bit larger than the diameter of the iron cylinder. This iron cylinder is picked up and dropped onto the ore, much in the manner of the old time stamp mills. This method seems to be popular in Australia. A more expensive but certainly faster and easier method is to use a small jaw crusher, such as ...
Stamp mill
A stamp mill consists of a set of heavy steel (ironshod wood in some cases) stamps, loosely held vertically in a frame, in which the stamps can slide up and down. They are lifted by cams on a horizontal rotating the cam moves from under the stamp, the stamp falls onto the ore below, crushing the rock, and the lifting process is repeated at the next pass of the cam.

· The investigation involved a toll milling contract, which saw a total of 16,931 tonnes of ore processed, producing 1, ounces of gold with an approximate value at the time of million.
Gold Leaching Plant Flowsheets – Gold Metallurgy
· The crushing section reduces runofmine ore to minus 1/2 inch which is further reduced by rod mills and ball mills to approximately 75% minus 200 mesh. Rod mill discharge is pumped over strake tables ahead of the ball mills with the concentrate being amalgamated, retorted and finally smelted. Final ground product goes direct to flotation before gold leaching by cyanide. The pyritic .

The ore cart took the ore rock to the stamp mill to be crushed before it could be chemically processed. This photograph of a small stamp mill in Virginia City shows the weights on rods that were lifted and dropped (stamped) onto rocks at the bottom of the structure. Then the finely ground rock was fed into the mill, generally by a gravity feed directly from the stamp mill. Then the rock was ...

Grinding Circuit
A combination of rod mill and ball mills are then used if the ore must be ground below 325 mesh (45 μm). Instead of grinding the ore dry, slurry is used as feed for rod or ball mills, to avoid dusting. Oversize and undersize materials are separated using a screen; oversize material goes back for further grinding.
