Ferrari-John, R., Batchelor, A., Katrib, J., Dodds, C., & Kingman, S. (in press). Understanding selectivity in radio frequency and microwave sorting of porphyry copper ores. International Journal of Mineral Processing, 155, https://doi.org/10.1016/j.minpro.2016.08.011

Continuous high-throughput microwave treatment followed by infrared thermal imaging (MW-IR) has previously been shown to provide attractive separations for a number of porphyry copper ores, leading to rejection of a large proportion of barren fragmen...

Pilot scale microwave sorting of porphyry copper ores: Part 1 – Laboratory investigations (2016)
Journal Article
Batchelor, A., Ferrari-John, R., Katrib, J., Udoudo, O., Jones, D., Dodds, C., & Kingman, S. (2016). Pilot scale microwave sorting of porphyry copper ores: Part 1 – Laboratory investigations. Minerals Engineering, 98, 303-327. https://doi.org/10.1016/j.mineng.2016.07.007

Microwave treatment followed by infrared thermal imaging (MW–IRT) has been proposed as a potential excitation-discrimination technique to facilitate sorting of porphyry copper ores. A continuous, high throughput (up to 100t/h), belt–based microwave c... Read More about Pilot scale microwave sorting of porphyry copper ores: Part 1 – Laboratory investigations.

A tool for predicting heating uniformity in industrial radio frequency processing (2016)
Journal Article
Ferrari-John, R., Katrib, J., Palade, P., Batchelor, A., Dodds, C., & Kingman, S. (in press). A tool for predicting heating uniformity in industrial radio frequency processing. Food and Bioprocess Technology, https://doi.org/10.1007/s11947-016-1762-6

Radio frequency energy is utilised for heating in a wide range of applications, particularly in the food industry. A major challenge of RF processing is non-uniform heating in loads of variable and angular geometry, leading to reduced quality and pro...

Increasing the grind size for effective liberation and flotation of a porphyry copper ore by microwave treatment (2016)
Journal Article
Batchelor, A., Jones, D., Plint, S., & Kingman, S. (2016). Increasing the grind size for effective liberation and flotation of a porphyry copper ore by microwave treatment. Minerals Engineering, 94, https://doi.org/10.1016/j.mineng.2016.05.011

In this paper, mineralogy, grain size, dissemination, textural consistency and mineral associations were determined for a commercially exploited porphyry copper ore using a Mineral Liberation Analyser (MLA). The ore was subjected to high power densit... Read More about Increasing the grind size for effective liberation and flotation of a porphyry copper ore by microwave treatment.
