##### Fine grinding in a horizontal ball mill ScienceDirect

From Bonds ball sizing formula, the recommended top ball size for this feed was 10 mm. This is the top ball size of Charge 2 (C2), the curve ( ) in Fig. 1, which should have produced the best grind. However, a finer grind was achieved using Charge 1 (C1), indicating that Bonds equation may not be entirely accurate for small mills and fine

##### Gold College of Natural Resources, UC Berkeley

One third of all gold is obtained from such by products. Silver and platinum are also recovered from the copper anode sludge in quantities large enough to more than pay for the total refining process. In obtaining gold from vein ore, the ore is first crushed in rod or ball mills.

##### The Mercury Problem in Artisanal and SmallScale Gold

Mercurydependent artisanal and smallscale gold mining (ASGM) is the largest source of mercury pollution on Earth. In this practice, elemental mercury is used to extract gold from ore as an amalgam. with little success. 3c, 36, but these techniques typically require relatively large gold grain size.

##### Stirred Mills Ultrafine Grinding ScienceDirect

Figure 10.1 shows the difference in energy efficiency between a laboratory ball mill and a stirred mill grinding a gold ore using 6 mm diameter alumina balls as media. At a fine grind size there is a clear advantage in energy consumption for a stirred mill over the tumbling mill. However, as the grind size coarsens, the difference in specific energy required to achieve the grind lessens.

##### Accurate Scale Up IsaMill Advantages Isamill

This accurate scale up is different than scale up for ball mills or other stirred milling technologies. In ball mill laboratory tests 25mm balls in a small laboratory ball mill have different trajectories and interact differently with the shell lifters and ore particles than in a large production ball mill.

##### Ball Mills Metallurgist amp; Mineral Processing Engineer

Working Principle amp; Operation. The apparent difference in capacities between grinding mills (listed as being the same size) is due to the fact that there is no uniform method of designating the size of a mill, for example a 5 x 5 Ball Mill has a working diameter of 5 inside the liners and has 20 per cent more capacity than all other ball mills designated as 5 x 5 where the

##### The effect of ball size on mill performance ScienceDirect

The specific rates of breakage of particles in a tumbling ball mill are described by the equation S i = ax i (Q(z), where Q(z) is the probability function which ranges from 1 to 0 as particle size increases.This equation produces a maximum in S, and the particle size of the maximum is related to ball diameter by x m = k 1 d 2.The variation of a with ball diameter was found to be of the form
