Benefits of the in-stream analysis system
In-stream analysis (ISA) systems provide continuous on-line analysis of metals and density in slurry streams around the flotation process. This information allows plant operators or a process control system to fine-tune and optimize the process much quicker after normal disturbances caused by variations in feed-rates, pulp density, grinding, head-grade, and mineralogy. Adjustments to pulp levels, aeration rates, reagent flow-rates, etc. can then be made to continuously maximize the recovery while maintaining the concentrate grades within the required specification.
Further benefit is derived from continuous, dedicated on-line elemental analysis by providing real-time indication of unplanned process upsets. Operators can react to such upsets immediately minimizing metal loses due to failure of reagent feeders or flotation cell level control valves or excessive recovery of gangue leading to high circulating loads in the cleaner circuit. The net result is a reduction in duration and magnitude of loss producing events in the minerals beneficiation operation leading to significant economic gains in terms of additional concentrate produced.
ISA systems are rugged, reliable, and requires minimal maintenance. Economic benefits include:
- Increases in recovery.
- Decreases in reagent consumption.
- Improved and/or more consistent concentrate grades.
- Reductions in man-power requirements.
- Greater efficiency of experimentation and innovation.
PGNAA provides iron ore beneficiation plant control
Prompt gamma neutron activation analysis (PGNAA) technology provides elemental analysis in the iron ore industry on both bulk materials and slurries. Used for process control in the coal and cement industries for decades, PGNAA technology has proven to be a successful measurement technique within iron ore beneficiation plants to help treat challenging ore types, improve efficiency and product quality, and control and stabilize the process.
The GS-Omni, a multi-stream PGNAA analyzer, provides real-time slurry elemental analysis of feed, concentrate, and tails streams within the processing plant. The analytical data from the analyzer can be exploited with a control strategy to correct and stabilize the plant on a much shorter time scale compared to lab analysis of control or composite samples, delivering significant economic benefits and greater operational flexibility. The economic benefits include more stable product quality, a reduction in reagent consumption, composite sampling and laboratory costs.
A critical requirement of any PGNAA analyzer design is to ensure uniformity of measurement across the volume of material passing through the analyzer. This ensures that every portion of the sample passing through the analyzer has an equal probability of being measured, which is consistent with sampling theory. A well-designed PGNAA slurry analyzer can essentially eliminate sampling and sample preparation errors associated with the material being analyzed, which are a limiting factor of the total error associated with laboratory assays or other online measurement techniques.
