An increasing number of mining operators are recognising the worth of early-stage geometallurgical research for good mine planning – and on the similar time, superior applied sciences like machine studying (ML) are enabling extra subtle insights than ever.
Current advances in underground mining know-how
Sustain-to-date with the newest developments in mining know-how
Australian underground mines are at the vanguard of efficiency. But it surely’s a fast-moving business, and important modifications have taken place lately.
The business has invested closely within the growth and implementation of recent mining applied sciences, with a give attention to digitization and automation. This has led to important enhancements to mechanized underground mining productiveness.
This whitepaper focuses on the 4 key mechanised mining actions: jumbo growth, long-hole drilling, LHDs, and decline trucking. It accommodates an in depth productiveness and price evaluation plus descriptions of current variations to mining methods and practices.

Specialists James McFarlane, Restricted Technical & Operations Director from Tungsten West, and AMC’s Principal Geologist Ian Lipton and Principal Geometallurgy Michelle Helm talk about how geometallurgy helps operators get essentially the most out of their mines.
The advantages of early-stage information assortment in good mining
One of many first rules of metallurgical research is to start out early, explains Lipton: “As quickly as you’ve found one thing that appears prefer it has the qualities that may make it a viable ore physique, it’s best to begin orienting your information assortment,” he says. “It’s necessary that you just take the utmost worth for each meter that you just drill.”
Early detection avoids mining operation challenges down the monitor
Early-stage information assortment permits the perfect planning choices to be made. It avoids challenges later down the road, since loads of the dear information that may be collected at this stage may be far harder to entry later. Whereas operators have historically been reluctant to spend cash early on, an increasing number of operators are recognising simply how a lot information is produced by their mines and the way invaluable it may be – and it’s by no means been extra necessary to be told.
Metallurgical research determine a mine’s strengths and weaknesses
“There’s a development whereby we’re having to course of extra advanced deposits,” provides McFarlane. “Because of this individuals want to start out eager about it early. Looking back, it’s all the time harder.”
The info collected in metallurgical research permits operators to determine each strengths and weaknesses of the mine, enabling them to perceive the very important realities of their operation.
“We’ve performed an enormous quantity of metallurgy and gathered important quantities of knowledge,” says McFarlane. “That has instantly influenced the redesign of the entrance finish of the processing circuit to make sure that we’re catering for our deposit in a ‘warts and all’ state of affairs.”
This sort of metallurgical research permits mine operators to transcend conventional predictive and geological modellings.
Mining geometallurgy facilitates a broader understanding of the challenge
“In my expertise, mining geometallurgy has been very a lot part of value-based planning as a result of it’s extra than simply making use of a predictive mannequin,” explains Helm. “With worth, you may perceive throughput, you may perceive recoveries, you may perceive focus grade. There’s a complete lot of knowledge that may be fed in to find out the place that parcel of ore ought to go.”
Whereas value-based planning has been round for a very long time, geometallurgy is taking it to a complete new stage. Instruments like ML present new ranges of granularity and the power to deal with a number of variants, reworking how we analyse information. It supplies new insights to permit miners to make the perfect planning choices.
Because the mining business continues to evolve, with rising developments just like the rise of electrical autos introducing brand-new demand for battery minerals, the function of geometallurgy guarantees to stay pivotal.
