The DYNOBULK Electric MPU’ s battery provides a range of 300 km on a single charge
series provides millisecond timing accuracy and precision, allowing for improved control over air blast, vibration and uniform fragmentation in muckpiles, the company says. DigiShot Plus XR and DigiShot Plus XRS also provide a 30 % increase in programmable time delay for enhanced design flexibility.
The company concluded:“ Since 1865, Dyno Nobel has been dedicated to unmatched explosives excellence. With the DYNOBULK Electric MPU and the DigiShot XR series, Dyno Nobel is proud to lead the mining industry into a safer, more sustainable and more productive future.”
500 and counting
Froth flotation stands as one of the greatest innovations in mining – and at the forefront of its modern evolution is the Jameson Cell: one of the most efficient, flexible and high-performing flotation technologies in the world.
The Jameson Cell was developed in 1985 when Mount Isa Mines asked Professor Graeme Jameson to improve flotation performance in its zinc circuit. His breakthrough – the downcomer – showed that effective particle recovery occurred in an intense mixing zone, leading to the creation of a compact, high-efficiency flotation cell.
In 2007, Glencore Technology, in conjunction with Professor Jameson, conducted a series of internal tradeoffs between the Jameson Cell and the Concorde Cell, with the hope of further improving fine bubble recovery. The evaluation revealed that the Concorde Cell delivered lower performance and, when coupled with operational complexity, had higher capital and operating costs.
As the capacity of Jameson Cells has increased to around 4,000 t / h, a recent lower-profile configuration was adopted, which does not compromise performance or functionality, but significantly reduces installation costs.
Now with over 500 installations across 30 countries, the Jameson Cell continues to deliver unmatched performance and reliability, Glencore Technology says.
Unlike conventional cells, the Jameson Cell generates fine bubbles consistently without the need for external equipment blowers or spargers. This ensures optimal particle-bubble contact and recovery with a lower capital cost, the company claims. Its intense mixing and rapid flotation occur without mechanical agitation, delivering superior energy efficiency and significantly lower operating costs.
Adam Price, Glencore Technology’ s Manager of Jameson Cell Technology, said there were a number of key advantages driving the cell’ s global success.
“ The Jameson Cell consistently delivers improved performance whilst providing huge savings on both OPEX and CAPEX,” he said.
The Jameson Cell achieves high throughput in a remarkably small footprint, while froth washing maximises concentrate grade in a single flotation stage, he added.
A recent independent study by Ausenco confirmed that the Jameson Concentrator – a complete flotation circuit built entirely with Jameson Cells – was a more cost-effective and sustainable flowsheet compared with tank cell flotation circuits. The Jameson Concentrator achieved a 24 % lower installed capital cost compared with tank cells, driven by its compact footprint and significantly reduced structural requirements. Costs were nearly half, with power consumption and consumables reduced due to the Jameson Cell’ s simplified, no-moving-parts design.
The study also found that the Jameson Concentrator produces 40 % fewer operational carbon emissions and uses half the concrete and one-third the steel during construction.
Rare earth wins
A homegrown project in the rare earths space has been getting a lot of attention lately, with JordProxa now firmly tied to its ongoing development.
The Eneabba rare earths refinery, in Western Australia, owned by Iluka Resources, is one of the first refineries of its kind in Australia and among only a handful outside China.
Iluka has entrusted JordProxa to deliver 10 custom designed modular evaporation plants for the refinery, plus supply a customengineered CO₂ capture plant.
The Eneabba refinery will produce separated rare earth oxides.
JordProxa’ s evaporation plants will play a vital role in the refinery’ s solvent extraction process. Each of the evaporation plants operates independently, ensuring no cross-contamination within the refinery. By using energy-efficient falling film evaporators powered by mechanical vapour recompression technology, the plants
The JordProxa CO₂ capture plant to be built at Eneabba is designed to recover carbon dioxide from boiler off-gas using an aqua ammonia solution, producing a controlled ammonium carbonate / bicarbonate mixture at the desired pH
