The ball milling process is carried out for approximately 100–150 h to obtain uniform-sized fine powder. In high-energy ball milling, vacuum or a specific gaseous atmosphere is maintained inside the chamber. High-energy mills are classified into attrition ball mills, planetary ball mills, vibrating ball mills, and low-energy tumbling mills.

At current gold prices this is worth about US$600. Both smelter treatment charges and oxidation or bio-leach costs are at least $200/t of concentrate and payables/recovery in the 90% range, so a minimum GSR for effective downstream processing is around 0.5. Clearly this is a function of gold price, but in the current gold price and cost

The smallest ball size typically charged into ball mills and tower mills is ½ inch (12.5 mm), although media diameters as small as 6 mm have been used industrially in Vertimills. In a laboratory study by Nesset et al .,[ 7 ] a GIS mill charged with 5-mm steel shot, and with other operating conditions similarly optimized, achieved high energy efficiencies when grinding to less than 20 μ m.

The ball mill rolls grinding media together with the ore, as the ore grinds, these balls initially 5-10 cm in diameter but gradually wear out. Grinding is always carried out under wet conditions, with about 70% solid mixture in water. This procedure maximizes ore production and minimizes power consumption.

The comminution product must be 80-90% passing 75 µm. Normally, the processes is employed when the gold content is ranging from 5 to 15 g/t. The grinding circuit is the first cyanidation circuit and the ball mill works as leaching drums. Once liberation is complete, the next step is to agitate the slurry to perform a complete dissolution of gold.

Ball Mills can be supplied with either ceramic or rubber linings for wet or dry grinding, for continuous or batch type operation, in sizes from 15″ x 21″ to 8′ x 12′. High density ceramic linings of uniform hardness male possible thinner linings and greater and more effective grinding volume.

From the ball mill, the gold ore powder is subjected to the process known as beneficiation for further crushing before classification and floatation processes. Most commonly, professional mining operations will use a shaker table at this point.

The ball mill is very similar to the SAG mill, except it has a larger proportion of steel balls to assist in the grinding process. Following grinding in the ball mill, the material is returned via the sump (8) to the secondary hydrocyclone (9) for resizing.

A ball mill also known as pebble mill or tumbling mill is a milling machine that consists of a hallow cylinder containing balls; mounted on a metallic frame such that it can be rotated along its longitudinal axis. The balls which could be of different diameter occupy 30 – 50 % of the mill volume and its size depends on the feed and mill size.

Forged Steel Balls are used for gold mining, cement factories, oil processing and large scale industrial applications. They are made by machine (standard) sizes 20mm–75mm. They are manually made (hit by air hammer) sizes 75mm–125mm. They have hardness 55–63 HRC. All forged balls are through-hardened, and shipped in 55-gallon steel drums.

Ball mills are a special instrument used to break up hard solids into a fine powder. They are similar to rock tumblers in that the instrument is a rotating container filled with heavy balls to grind the substance into powder. Ceramic material, crystalline compounds, and even some metals can be ground up using a ball mill.
