Breakthroughs in mining have been recognised at two different science and innovation awards, with an ore sorting sensor and minerals processing technology among the winners.

The CSIRO’s David Miljak won the minerals and energy category at The Australian Innovation Challenge for his ore sorting sensor.

Judges said Miljak’s technology could boost copper production efficiency by more than 20 per cent.

“The sensor can distinguish high grade from low grade ore quickly as tonnes of rock containing the copper mineral chalcopyrite pass along a conveyor belt from the mine,” they said in a statement.

“It promises to cut processing costs greatly by enabling the rejection of batches of ore low in the mineral.”

In a separate competition University of Newcastle professor Kevin Galvin won the Ian Wark Medal for contributions to Australian science.

Galvin invented the Reflux Classifier, a technology used in minerals processing to clean ore.
