In 1933 my dad got permission from one of the owners of a gold mine in the Mojave desert to go out there and see if he could get any gold out of it. This mine had been closed down for many years, but all the equipment was still there.
The extraordinary success of the Snip gold mine is in direct contrast to numerous gold mines developed during the heady years of flow-through financing which all too often failed to live up to expectations.

- mills gold to very thin flakes, - stains the gold with iron - not good for batch processing - in non-mining countries, balls difficult to find - high investment costs compared to capacity Ball mill Advantages - product size can be very fine e.g. for flotation, 150 m - works with very hard material - can be built locally in experienced ...
It replaces a conventional ball mill, impact mill, hammer mill, tower mill, etc. Ultra fine Raptor milling has created the potential to revolutionize the mineral processing industry due to the benefits attained through being able to economically mill finer and enhance particle
The fine ore passes through an open circuit 2.7 x 3.8-metre rod mill and a 3.8 x 4.7-m ball mill in closed circuit with cyclones to produce a grind of 85 passing 200 mesh. Grinding circuit underflow is pumped to two Knelson concentrators then passed over a shaking table to recover the free gold.
Aug 06, 2019 The massive 621m Gruyere gold project in Western Australia poured first gold in late June. Once ramp up is complete, Gruyere a 50-50 JV between Gold Road Resources ASXGOR and Gold Fields will produce about 300,000oz a year over its initial 12year life. Its a remarkable accomplishment, because not too long ago the 1.2bn Gold Road was just another struggling
May 12, 2016 We started drilling and found two deposits and switched it to a heap-leach mine. Even though gold was US275 per oz. at the time, we were able to produce gold for US125 per oz., so we were pretty profitable. McDonald adds that we mined the whole thing out at sub-US300 per oz. gold, so it was only a five-year mine life.
