The maintenance cost compared to the equipment value is different depending on industry. For example, a mining operation has a much higher MC/ ERV than a fixed plant operation. A Mining corporation that is considered an industry leader recently surveyed the MC/ERV number in 11 mine locations. The MC/ERV ranged from 18% – 36%.
These costs represent 30% of costs for the 1 Mt/a plant and over 50% of costs for the 20 Mt/a plant. Thus, the "efficiency" of a modest plant is improved by simplifying the comminution circuit and reducing labour requirements. Improving the grinding efficiency of the comminution circuit by 10% will improve plant operating costs by less than 3%.
CAPITAL COST ESTIMATE The overall project capital cost estimate was developed by GR Engineering Services (GRES) for the DFS and is based on an Engineering, Procurement, Construction and Management (EPCM) approach for The estimate pricing was obtained predominantly the process plant and infrastructure. The estimate includes all the necessary costs
10,903 mine blocks was used as the basis of the grinding plant design. GRINDING PLANT DESIGN The plant design was conducted using . the CEET internet-based software developed by SGS Minnovex. This software can simultaneously handle the grindability values for enormous numbers of mine blocks (limited only by computer memory) to produce an ...
Unlike capital cost estimation, which is based primarily on the size and unique nature of the mine and plant site, estimation of operating costs depends on the assessment of the probability of imperfect coordination of human effort in equipment opera tion and consumption of supplies. To standardize calculations, the majority of the equations

The adequate cost estimation of mill plants plays a crucial role in the success of feasibility studies of mining projects. Grinding is one of the most important operations in mineral processing plants and assumes a substantial share of the total milling costs. The objective of this work was to develop a set of cost functions for major grinding ...
An hydrocyclone is to be installed in a closed circuit grinding circuit with a mill discharge containing 30% solids by volume. The solid density is 2800 kg/m 3 and the density of water is 1000 kg/m 3. Given that the maximum pressure deferential between the inlet and overflow was 50 kPa and the throughput from the mill was 800 t/h, estimate:1.

Mining Cost Service continues to be a useful reference on a wide range of topics for early stage mine planning through to 'fill the gaps' on more detailed studies. Mining Cost Service provides an independent source for information on equipment, quantities and cost for a significant number of mining methods and range of production rates.

It allowed its mill operations team to become far more involved with the general mining process than normal. That could become a blueprint for other operations to improve outcomes. Evolution's Mt Rawdon operation, 75km southwest of Bundaberg in Queensland, is a low grade mine – 0.7-1 grams per tonne.
A comminution circuit is an important integral part of a mineral processing plant. Nearly 40% of the capital cost and 30 to 40% of the operating cost are taken up by the crushing and grinding circuit. Therefore, considerable care should be …
Under this approach, you estimate the total output expected from the mine, and then amortize the proportion of the total output actually mined. So, if the capitalized amount of development costs is $1 million, and the mine has just produced 2% of the total amount of expected ore, then you can charge 2% of that $1 million to expense in the ...

» Process plant – costs include labour, power, reagents, maintenance, freight, general expenses and and flights for all personnel, product transport and Perth office costs. COST ESTIMATE SUMMARY Operating costs have been estimated on a monthly basis for the first two years, then quarterly for a further two years and then annually thereafter.
The availability of water is a long-term concern for most mine planners, especially for most low-grade copper mines that usually have a lifespan that exceeds two decades. The water required to operate a flotation plant may outweigh all of the other uses of water at a mine site, and the need to maintain a
