At present the main aggregates for fine grinding of gold ores are ball and similar mills, in which in addition to mass ore grinding, deformation and free gold destruction occurs. The article aims to study the process of deformation of free gold extracted during grinding and to develop a ball mill design to preserve the commercial component.

The earliest, and simplest method of crushing ore was the use of arrastras. When enough capital was available, stamp mills replaced arrastras at most mines. The following sections take a look at various types of stamp …

Location. Texas. Mar 8, 2010. #2. dalmatiangirl61: In the order you have listed; a ball mill can fine grind down to <400 mesh if needed, a rod mill will efficiently grind to 150/200 mesh range, and a roll mill can do a +/- 100 mesh.

Hard ore Work Index 16 = 100,000/65,000 = 1.54 kwh/t. For the purposes of this example, we will hypothesize that the the crushing index of the hard ore with the increased energy input of 1.54 kw/t reduces the ball mill feed size to 6,500 micrometers. As a result, the mill output will increase with this reduced size to approximately 77,000 tons ...

Fault 1: The mining ball mill makes loud noise. Reason: One of the reasons for loud operating noise may be unbalanced load distribution in the mill. Uneven distribution of material may cause uneven grinding media wear or excessive vibration, resulting in additional noise. Another possible cause could be worn or damaged bearings, which …

Crushed ore is fed to the ball mill through the inlet; a scoop (small screw conveyor) ensures the feed is constant. For both wet and dry ball mills, the ball mill is charged to approximately 33% with balls (range 30-45%). Pulp (crushed ore and water) fills another 15% of the drum's volume so that the total volume of the drum is 50% charged.

Some other key drivers in flowsheet selection at the hashing stage are: Supergene weathering. This is common in tropical environments (e.g. West Africa) and typically oxidises gold-bearing sulphides down to 50-100m, transforming commonly refractory gold in sulphides to 'free-milling' gold, behaving in a similar fashion to gold …

The size analysis of a gold bearing ore crushed in a jaw crusher indicated that 80% passed through a 3000 micron sieve. Further size reduction was completed in a 1.0 xx1.5m wet ball mill rotating at 78 % of the critical speed to liberate the gold. Determine the maximum size of the balls at the ommencement of grinding. Data: S.G. of the ore =3.86.
