The Laws of Simplicity (Simplicity: Design, Technology, Business, Life)

Eventually, we're studying that simplicity equals sanity. We're rebelling opposed to know-how that's too complex, DVD gamers with too many menus, and software program followed through 75-megabyte "read me" manuals. The iPod's fresh gadgetry has made simplicity hip. yet occasionally we discover ourselves stuck up within the simplicity paradox: we'd like anything that's easy and simple to exploit, but in addition does all of the complicated issues we would ever wish it to do.

Magnetite is also a key source of iron in many countries where haematite resources are not present, and regions such as Northern Africa, Central Europe, China, and North America have operations mining and treating magnetite. In these operations, traditional comminution technology such as ball mills and tower mills are common practice, and the large tonnages treated in these plants results in large amounts of power being used for grinding the ore. However, with the development of IsaMill™ technology for coarse grinding applications in base metals, there is also significant potential for the IsaMill™ to be used in magnetite operations.

Smelters). The updated capital, processing and realisation cost estimates would be included in the project financial model. The project metallurgist should be proactive in reviewing the total model to ensure its completeness and accuracy from a processing perspective and to reduce the risk of items being omitted or double counted, particularly at the process plant-mine and process plant-infrastructure interfaces. The feasibility study would normally include a project risk analysis to AS/NZS 4360:1999 and the project metallurgist would be required to provide input, attend any workshops and review results.

A range of corresponding preliminary processing cost estimates would be produced from either current cost data from similar operations or from first principles. Unless sufficient and current processing cost data are readily available, the setting up of a processing cost model that reflects fixed and variable cost components is recommended. Once established, the model can then be used over a range of processing rates and refined as the project develops. Table 2 shows typical sources of scoping level processing cost estimates and Table 3 shows results that may typically apply to a simple large-scale base metals plant.
