Mining, mineral processing, and mini-machines

Abstract A mini- or micro-machine is a small electro-mechanical device. There are several existing applications of micro-sensors such as the accelerometers used in automobile airbags or the force sensors and grippers used at the ends of micro-surgery tools. Potential applications of existing mini- and micro-technologies are possible and could be used to improve the control and efficiency of fragmentation, heap leaching and other mining and mineral processing operations. A more radical proposition is to devise mass-produced, possibly disposable, mini-machines that would operate in large groups. These would be the basis of highly selective, efficient, flexible, and clean mining and mineral processing methods. The paper is intended to promote discussion of how innovative applications of mini-technologies can be used to improve and radically change current mining and mineral processing methods.

Summary: The integration of mining and mineral processing technologies into new advanced mining systems is considered to offer several benefits, including selective mining, reduction in waste, increased productivity, flexibility, and improved resource utilization. This paper focuses on underground hardrock mining and the integration of pre-concentration technologies into future mining systems as representing realistic, shorter-term integration options. Control of fragmentation to optimize grinding,...

Summary: The notion of "value" has always been a subjective and contentious issue. Indeed, value is in the eye of the beholder . There are as varied methods and practices for valuing property, as there are industries in which they are applied. For example, there is replacement value, insurance value, salvage value, appraised value, book value, and fair market value, to name a few, although in the mining industry, valuations usually refer to fair market value. In the Canadian mining industry, at...

Summary: As mines utilize more automation in mining operations to improve efficiency and safety, a corresponding increasing demand is placed on the transport of information. Some of the recent technological advances in underground telecommunications are described for various data, voice and video applications. In particular, two new innovative underground communication systems are described, one with highspeed data at 30 Mbps and the other for minewide evacuation and safety applications. The high-spee...
