Ultra fine grinding of the plant tailings of a refractory silver ore was studied using a laboratory type vertical stirred media mill. Preliminary tests confirmed that ultra fine grinding substantially improves the extraction of silver from the tailings in cyanide leaching ( 36% Ag extraction rate from the asreceived tailings with d 80 of 100 μm, 84% extraction rate after ultra fine ...

This study investigated ultrafine coal grinding performance of four low to moderatecost grinding media in a laboratory stirred mill. Kinetic grinding tests showed that silica beads generated the finest product size with a P 80 of μm from a feed size of μm while having a specific energy (SE) input of 309 kWh/ton. Nonetheless, the least energy consumption of 109 kWh/ton was ...

If economical, subsequent fine and ultrafine grinding takes place, using either ball mills or stirred media mills. The definition of fine and ultrafine grinding varies, but fine grinding is often considered to take place below P 80 values (the size that 80 wt% of particles pass below) of 100 μm [7] and ultrafine grinding below P 80 values of ...

Scaleup to 100 t/hr is expected to be feasible. Abd ElRahman (CMRDI) studied ultrafine grinding of a variety of minerals in a planetary mill as a function of the rotation speed of the canisters and the presence and size of grinding media in the canister. The advantage of higher rotation speed levelled off at higher speeds, possibly due ...

1. Fine grinding in the mining industry. It has been estimated that approximately 2% of the world's energy usage is applied to mineral comminution, and around a quarter of this is used specifically in metalliferous ore grinding [1] where it is typically the most energy intensive set of operations [2].The purpose of comminution in ore processing is to reduce particle size in ...
