Rod Mills - Mineral Processing & Metallurgy
Rod Mills may be considered either fine crushers or coarse grinding equipment. They are capable of taking as large as 2″ feed and making a product as fine as 35-48 mesh. Of particular advantage is their adaptability to handling wet sticky ores, which normally would cause difficulty in crushing operations.

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 by size and density.

Rod mills, how they function - Mine Engineer
Rod mills are very similar to ball mills, except they use long rods for grinding media. The rods grind the ore by tumbling within the the mill, similar to the grinding balls in a ball mill. To prevent the conditions leading to rod charge tangling, the length to diameter ratio is maintained at 1.4 to 1.6. Rod mills accept feed up to about 50 mm ...

Assessing Mining Knowing the energy consumption for mining, at both the extraction stage [22] and the crushing and grinding stage, the impact of energy use in mining can start to be assessed. Figure 7 is an illustration of how this can be done using SLCA.
The use of cyanide in gold mining - The Violence of ...
In recent years the use of cyanide in gold mining has become the dominant means by which gold is extracted from a body of ore. The mercury amalgamation process had previously been used but recovered only about 60 per cent of an ore body's gold. In contrast, leaching finely ground ore with cyanide can recover up to 97 per cent of the ore body ...

Rod Mills - Mineral Processing & Metallurgy
The Rod Mill encourages the use of a thick pulp coating both the liners and the rods, thus minimizing steel consumption. Continuous movement of the pulp through the rod mass eliminates the possibility of short circuiting any material.
Optimization of mill performance by using
Mill power Usually, plant operators use mill power readings as an indicator of ball filling degree and, often, try to keep it at the maximum level. It is well known that the mill absorbed power depends on operating parameters other than ball level, such as pulp density and liner configuration. Figure 2 shows that there is no linear relation between
