Venue: Parq Grand Ballroom
Time: 1:30 p.m.

Despite the recognized significance of ground product fineness on both line capacity and downstream process performance (typically flotation), less than 10% of mineral ore concentrators today use particle size measurements in automatic control applications for the final product particle size.

Although “near-line” particle size measurement instrumentation has been in place for several decades and is commonly installed in most modern concentrators, its availability and low measurement frequency have typically been inadequate for reliable use in automatic control. Their low availability is often due to problems with slurry sampling and transport systems required to deliver samples to the measurement instrument. Recently an innovative technology for real-time particle size measurement has been developed by CiDRA Minerals Processing, under its commercial name CYCLONEtrac™ PST, already proven in several commercial installations, demonstrating near 100% availability with minimal maintenance, thus overcoming the limitations of previous technologies.

Investment decision makers require convincing, reliable estimates of the expected economic value that automatic grind control projects would deliver. This paper presents a methodology for estimating such value from the installation of the new PST particle size measurement technology, capable of tracking particle size on each individual hydrocyclone overflow stream, adding significant new options for improved process stability and performance. Based on actual plant operating records, accumulated over long periods of time, the evaluation approach here described assess and highlights the significant potential contribution to be expected from this unique PST technology.

This is an extension of previous work, adding the following: statistical uncertainty to the predicted value of PST; examples from existing commercial installations of how PST enabled improvement in the basic throughput vs size, and recovery vs size relationships of the plant; and provides examples of analysis of data sets from other plants.

CiDRA will also be exhibiting at the event, so please stop by the booth to discuss the advantages and benefits this solution will bring to your process.
