Ore processing. The copper concentrator was rebuilt in 1973, with rod and ball milling and three-stage flotation, to supply the roaster and conventional blister copper smelter on site. In 1981, Mount Isa commenced anode casting as well. In 1988-1989, two 6.4MW AG/SAG grinding mills replaced the rod and ball mills at a cost of A$35m.

In obtaining gold from vein ore, the ore is first crushed in rod or ball mills. This process reduces the ore to a powdery substance from which the gold can be extracted by amalgamation with mercury or by placer procedures. About 70% is recovered at this point. The remainder is dissolved in dilute solutions of sodium cyanide or calcium cyanide.

Mineral Reserves are reported using long-term copper, gold, and silver prices of $2.75/lb, $1,500/oz, and $18.50/oz, respectively. An average CMM copper process recovery at block model domain recovery, gold process recovery of 65%, and silver process recovery of 70% is based on geo-metallurgical domains and actual plant values.
In the second concentrator, material with a copper grade over 0.555% is sent to a three-phase milling circuit, where the ore size is reduced to approximately one-half inch. The ore is then sent to a circuit of six ball mills, which grind it to the consistency of fine powder.
Figure 2. Ball Mill Grinding Circuit The ball mill is in closed circuit with a sump and three cyclone classifiers. The ore and trim water are added to the ball mill and the outflow from the ball mill goes to a sump where additional water is added. The slurry from the ball mill is pumped out of a sump into two cyclone separators. The underflow ...
Ore is treated using a two-stage crushing process, followed by a two-stage grinding circuit that consists of a semi-autogenous grinding mill and a ball mill. Most of the ground ore is fed to a gravity circuit that recovers about two-thirds of the gold, which is then smelted on site to form dor bars.

The ore is crushed in a primary crusher at a nominal 8,000 tonnes per hour and conveyed to a primary ore stockpile. The primary ore is then ground (two trains each comprising a SAG mill and two ball mills) to a final grain size of approximately 180 microns.
(powdered) in a stamp mill shown in Fig. 16.2. The heavy stamp rises and falls on a hard die to powder the ore. The powdered ore is then taken out through a screen by a stream of water. Pulverization can also be carried out in a ball mill. The crushed ore is taken in a steel cylinder containing iron balls. The cylinder is set into revolving motion.
After the ore has been crushed, it is ground to a fine powder in a ball mill which also contains weak sodium cyanide solution. The silver sulfide and also any free silver present reacts with the sodium cyanide to yield sodium argentocyanide, Na[Ag(CN) 2 ], which is soluble in water.
