Mercury Amalgamation
At the Gold Hill mine, northeast of Boise, Idaho, the ore assays $6 to $8 per ton, and 92 per cent is saved by amalgamation. The gold is free in quartz but closely associated with a lead- bismuth mineral. The ore is crushed through 35 mesh in a ball- mill, and the first gold is caught in hydraulic traps in this grinding circuit.Web

SAG vs. AG Mills: Understanding the Key Differences
SAG mills use a combination of steel balls and rock particles as grinding media, while AG mills use only the ore itself. Both types of mills are used for grinding ore in mineral processing operations, but SAG mills are larger in size and can grind larger quantities of ore. AG mills, on the other hand, are smaller and are typically used for ...Web

Basic Ball Mill Grinding Circuit
The correct operation of a mill with proper load of balls and pulp or ore feed is determined by sound or by power meter. Normally, the sound is a rumble, whereas from a more or less empty mill there is a rattle. The speed of mills depends upon their diameter; a ball-mill of 3 feet revolves 35 times a minute, and one of 5 or 6 feet, 29 or 27 times.Web
