The primary mill maintenance goal should be to ensure the milling asset is available for operation 100% of planned operating time (100% reliability). Every piece of equipment is important and can put the mill down or cause inferior product quality, reduced production rate or yield.
SAG Mill Circuit Example — Gold Processing SAG mill circuit example for gold processing [image: (13563)] AG/SAG Mill. AG/SAG mills are normally used to grind runoffmine ore or primary crusher product. Wet grinding in an AG/SAG mill is accomplished in a slurry of 50 to 80 percent solids. 2D and 3D simulations of particles in a SAG Mill
The most well known carboninpulp plant remains the prototype Homestake plant in Lead, South Dakota. Operating since 1973, this facility treats 2130 tonnes of ore per day averaging g gold per tonne. Homestake has also operated small silver carboninpulp plants at Creede and Cripple Creek, Colorado since 1979.

1. Introduction The concept of a generic flow sheet for the processing of gold ores may seem to have been superseded, given the foregoing discussion of many unit operations and process configurations.
Low initial cost for a complete mill which is ready to operate; Mill can be easily transported from one place to another; Small isolated ore deposits can be worked that would not justify a permanent mill installation;
Leaching Gold Circuits. This flowsheet is the lowest in price, and can be used on what are commonly termed as "free milling" gold ores where a high percentage of the values are free and where these values are unlocked at reasonably coarse grinding. This flowsheet is often used for treating high grade pockets.

1. Introduction For the vast majority of ounces of gold produced, comminution costs in the form of power, grinding media, and liners represent the single largest cost category of milling. Heap leach operations, of course, have a substantially lower milling unit cost.
The Mineral Processing Flowsheets shown on the following pages are based on actual data obtained from successful operating plants. Metallurgical data are shown in these flowsheets which incorporate Crushers, Grinding Mills, Flotation Machines, Unit Flotation Cells, and Selective Mineral Jigs as well as other standard milling equipment. The Flotation Machine, the Selective Mineral Jig and ...
This study has found that in general the relative Mining and Milling costs of a given operation do not significantly differ, and generally fall within the range of 43:43:14 to 45:45:10 (Mine:Mill:G A). In addition, G A costs were found to be consistently lower than both Milling and Mining costs.

Energy costs typically comprise one of the largest ongoing costs of mining operations, of which 70% is devoted to the comminution of the ore (Norgate and Jahanshahi, 2010). Furthermore, the most significant energy cost occurs in the grinding circuit of the Milling section, where up to 97% of the energy cost is incurred (Ballantyne et al., 2012).
Operating costs for gold miners are typically broken down into several categories, including but not limited to, purchase of mining equipment, mining license, generator rental, fuel, staff wages, mining inputs, external contractors, transportation costs, insurance, and facility maintenance.
