Due to the low rotation speed of the sizer, the teeth sizing elements and drive train are protected against excessive damage from any unexpected tramp metal within the feed entering the crushing chamber. Slow sizer speeds maximise tooth wear life due to a more effective bite on the incoming feed. Rolling with the punches

Such a circuit can counteract the effects of harder ore. coarser ore. decrease the size of SAG mill required, or rectify poor throughput due to an undersized SAG circuit. Notably, harder ore often presents itself to the SAG circuit as coarser than softer ore—less comminution is produced in blasting and primary crushing, and therefore the ...
The hydraulic system allows one roll to react to overload incidents by retracting and letting tramp metal or overloading material pass through the gap. Unlike with Roll Sizers, DRS therefore have less need for personnel entering the crushing chamber. This way the Double Roll Crusher ensures the safety of service personnel.

How HPGR improves gold recovery. There are two main ways mines recover gold ore from the gangue, and HPGRs can assist with each process. One of them is heap leaching and for mines using this process, we've found that the most efficient setup is to have a HPGR perform tertiary grinding immediately prior to recovery, completely avoiding the …
A gold oxide ore from a Ghanaian mining operation was used in this investigation. The ore was milled and prepared into feed sizes ranging from 50–90% passing 106 µm and leached over 24 hours using conventional bottle roll test. The differing ore size fractions were leached individually in a well-mixed pulp (55 wt.%) at pH 10.5–11.
The finely ground undersized ore, which bypasses the gravity circuit, is treated by a flotation circuit to recover the gold which is entrained in the finer size fractions. The ore is mixed with amyl xanthate flotation reagents in a conditioning tank prior to entering the rougher flotation cells. These are two lines of OK cells each with ten tanks.
