improvement in mill throughputs and better mine to mill reconciliation indicating lower dilution levels (Gaunt et al. 2015, Kanchibotla 2013, Rogers and Kanchibotla 2013, Engmann et al. 2012). A general perception of mill optimization is simply increasing blasting energy to produce finer fragmentation. However, this may not be applicable in all ...

• By process (short range to long range model, mill to mine production) A combination of the above methods may provide the best fit for an operation. Any reconciliation program is recommended to be based upon clear concise goals. Reconciliation methods should be specifically adapted to handle the unique problems that occur at each operation.

Reconciliation involves the collection of tonnage, grade (quality) and contained metal (product) data from disparate and hopefully independent sources. Examples are exploration data, production sampling data from blastholes or drawpoints, and process plant data. These data may be compared by means of ratios (factors). The F1 factor usually relates shortterm (ore control) model tonnages ...

At Boddington the process residence time is about two days, so in a month two days of mill reporting is based on material from the previous month and two days of crusher feed at the end isn't reported fully in the mill figures. This means that for a 30 day month 13% of the material is unmatched in the reconciliation.

Optimization. Only once all of the above is in place, and the system is stable and under control, can true mineral resource throughput optimization opportunities be realized. Base metal mining operations in particular usually exhibit opportunities for minetomill optimization, whereby stable and consistent plant performance can be achieved.

Like many catchy mining phrases, "Drill to Mill," "Pit to Plant," "Mine to Mill" and "Mine to Market" are deceptively simple descriptions for complex, multilayered processes. In the mining cycle, drill and blast (DB) is arguably the first and most important step to get right. DB operations impact the entire mining process, from mining equipmentRead More

Frequently MinetoMill optimization demands technology transfer to the industry. The four steps of MinetoMill optimization are shown in FIGURE 3. An example of this kind of optimization is the optimal blasting design in order to achieve lower costs as possible. This can be done by two ways: decreasing the energy consumption in crushing and ...

The operating cost of any mining operation relates to the amount of materials mined and handled. Profit is directly proportional to ore grade and its quality. Economic and technical considerations establish the optimum grade to optimize this profit. There are several studies that discuss the benefits for the integration of mine and mill operations.

They increased the sag mill throughput using fragment optimization. Jansen et al. (2009) tracked the ore fragment due to mine blasting to estimate the plant performance. They structured an MTC optimization for monitoring the concentrator and stockpile. They used radiofrequency identification (RFID) tracer technology to track coarser ores.
