First of all, in order to get the best out of how this particular equipment is used it is important to get acquainted with knowledge on what it is, and is made of. Hence, a mill is a piece of equipment used to grind ores. Its major purpose is to perform the grinding and blending of rocks and ores to release any free gold that is contained within them. At major mines, the mill was the critical equipment that was required to process the ores that were extracted from deep underground. Many early mines used stamp mills, but many operations today find that ball mills are more functional for smaller operations and perform well with the modern equipment we have available now such as combustion engines.

To perform its functions, the ball mill operates on the principle of impact and attrition. This principle entails that the balls are dropped from near the top of the shell in order to bring about size reduction impact. The major components of the ball mill include a shell that is hollow and is suspended on its axis to bring about rotation. The axis of the shell can be suspended horizontally or at an angle to the horizontal. The shell is filled with quite few, but reasonable amount of balls which do the grinding process, and can be made of steel such as chrome steel and stainless steel. They can also be made of ceramic or rubber depending on their targeted material to be ground. Meanwhile, the surface of the inner part of the shell is in most instances coated with an abrasion resistant material which may include manganese steel. Its major operations are categorized into two, namely the dry and wet processes. Through those processes the machine is able to perform its functions of grin...
Now here is what one must know with regard to how the ball mill operates. The drum of the mill is suspended on two self aligned rollers. Then the material to be worked on is loaded through the hopper. From there, the mill is driven using a motor with a clutch, gearbox and the flexible coupling. The mill is then lifted to a certain level of height as it rotates. It is from that height that the balls begin to freely fall or roll down in order to grind the material that has been loaded. After the material is ground, it is then removed from the mill depending on the discharge method used on the machine. For example, there are center unloading mills as well as unloading through the grille mills. For the center unloading mills, the ground material is discharged through a hollow unloading trunnion using a free sink. To make it more efficient the pulp level in the drum should at least be above the level of the lower generating trunnion for unloading. On the other hand, mills whose u...
The ore is sent into a single cylinder hydraulic cone crusher for the secondary crushing. Thereafter, the gold ore is transferred to a multi cylinder hydraulic cone crusher, where the ore is crushed further into finer material. From there, the crushed gold ore is sent to a ball mill, evenly as it passes through a vibrating screen for grinding. 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 tableat this point. These are extremely effective at capturing tiny particles of free gold that has been released from the ores.

Gold Ore an overview ScienceDirect Topics. The above pre treatment stages can be changed based on ore mineralogy. For a complex AuAg ore, direct cyanide leaching resulted in only about 47% and 19% extraction of gold and silver even after very fine grinding at . 38 µm.Diagnostic leaching was carried out to assess the nature of refractoriness 29.Depending on the results of the diagnostic test ...
Ultrafine grinding is used to liberate gold finely disseminated in metallic sulfides. KCGM is the first gold mine using ultrafine grinding followed by cyanidation . The gold sulfide concentrate is grind with an IsaMill to a P 80 of 1012 μm.
