A ball mill, a type of grinder, is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium. Different materials are used as media, including ceramic balls, flint pebbles, and stainless steel balls.

The ore is first reduced in size (typically 80% passing 75µm) to ensure that all nonrefractory gold is readily accessible for cyanide leaching. There are several variations of comminution circuits used in the gold industry, such as: Multistage crushing and pebble and/or ball milling .
Ball mill A steel cylinder filled with steel balls into which crushed ore is fed. The ball mill is rotated, causing the balls to cascade and grind the ore. Banded iron formation A bedded deposit of iron minerals. Basalt An extrusive volcanic rock composed primarily of .
further reduced in size. Water is added to the ball mill, in which a slurry that usually contains from about 20 to 55 percent solids is produced (Singh, 2010; International Mining, 2011) (see fig. 2). The mill operates in a closed circuit with screens that size the ore and cyclones that sort the ore .
· Gold/silver base metal concentrate deportment. Smelters typically pay >95% (Au) and 90% (Ag) in copper and lead concentrates, but will only pay 6070% (maximum, depending on degree of Pb/Zn smelter integration) for gold and silver in zinc concentrates. Cost drivers are also important in flowsheet selection, and are summarised in Table 3.

· Hummingbird Resources' plan to install a second ball mill and increase production capacity at its Yanfolila gold mine, in Mali, is tracking ahead of expectations, the company says. The second ball mill will increase throughput capacity from 1 Mt/y to Mt/y when operating at fresh ore and from Mt/y to Mt/y when processing a blend of ore types, according to Hummingbird.
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.
Recognize important considerations in ball mill selection. Reading Lecture. In ball mills, steel balls or hard pebbles to break particle based on impact and attrition. A rotating mill charged with media and ore is lifted against the inside perimeter. Some of the media falls and impacts the ore particles at the bottom of the mill.

· SAG mill make use of steel balls included with some large and hard rocks for grinding. These mills utilize the balls in making the large fragments of materials broken into pieces. The ball charge of a SAG mill is about 9% to 20%.This process takes place inside the large rotating drum of SAG mill which is filled with balls partially.
