The Victorian gold rush from 1851 to 1896 produced over 61 million ounces of gold. In those days, head grades were high and recoveries were low by today's standards. The principal method of comminuting the hard rock ore was by stamp mill batteries which pulverised rock (rather than grinding it) within a wet mortar box.

- Endomines announced Friday that ore mining at its Pampalo gold mine in Finland has started ahead of schedule and that the mill is about to start operations, too. The company said that the deepening of the mine reached the targeted 815-mining level in November.

At current gold prices this is worth about US$600. Both smelter treatment charges and oxidation or bio-leach costs are at least $200/t of concentrate and payables/recovery in the 90% range, so a minimum GSR for effective downstream processing is around 0.5. Clearly this is a function of gold price, but in the current gold price and cost ...

Free-milling gold ores are defined as an ore from which standard cyanidation (which takes about 20-30 hours) can extract more than 90 % of the gold, under the condition that the ore size is 80 % < 75 µm (Joe Zhou, 2004). Complex ores, meanwhile, require significantly higher cyanide or oxygen levels to attain an economic recovery (Brooy, 1994).

The Granites processing plant comprises a three-stage crushing circuit followed by two stage series ball milling to grind the ore to a cyclone overflow P80 of typically 60 to 100 µm ahead of gravity concentration, cyanide leaching, and gold recovery. All gold recovered is processed on site to produce gold doré bars.

Gold mineral type, referring to the most general description of the ore, such as "Free milling" or "Silver rich", and gold concentration, or Gold ore grade, were relatively straightforward to model into attributes. Other valuable minerals, such as silver, were not seen being as characterising as gold with regards to process design and ...

The processing plant has a nominal capacity to process approximately 40 million tonnes of ore per year with optimization projects underway to further increase this capacity. The cyclone overflow from the mill circuit is treated in a flotation circuit that produces a copper–gold concentrate for export.

shown in Figure 2, is designed to reduce 41.5 tons/hr of gold ore from a feed range of 2-5" to 160 microns. The mined ore is fed using a Grizzly Feeder, F-101, into a Jaw Crusher, J-101, where 80% of the ore is crushed to 1.75" or smaller. The remaining 20% are recycled back into F-101 (not shown on PFD) .
