KPS to leverage ETC tech in hybrid power conversion at Iluka’s Jacinth Ambrosia mine

Pacific Energy Ltd’s wholly owned KPS subsidiary has signed a contract to convert its 10 MW diesel power station at Iluka Resources’ Jacinth Ambrosia mineral sands mine in South Australia to a hybrid facility.

The facility will incorporate electric turbo compounding (ETC) technology, which, the company says, allows generators to maintain the same power output using less fuel and producing lower CO2 emissions.

The conversion and upgrade will have a meaningful impact on lowering emissions and fuel costs for Iluka, Pacific Energy claims.

KPS has operated the 10 MW diesel power station at the Jacinth Ambrosia site since 2009. Under the new contract, which runs for an initial term of seven years, KPS will:

  • Install 3.5 MW of solar power generation;
  • Integrate the solar array with the diesel power station; and
  • Introduce ETC technology to each of the 10 1 MW generators.

ETC technology makes generators work more cleanly and effectively by recovering waste energy from the exhaust to improve power density and fuel efficiency, the company explained.

Juwi Renewable Energy Pty Ltd, the Brisbane-based subsidiary of juwi AG, is to construct the medium penetration solar/diesel hybrid power solution for Jacinth Ambrosia, with KPS owning and operating the hybrid project. After completion, it is expected to deliver almost 21% of the mine site’s annual electricity needs.

Pacific Energy Chief Executive, Jamie Cullen, said: “This is an exciting development for both Pacific Energy and Iluka Resources in what we believe is a world first – integrating solar and ETC technology with an existing fossil fuel facility. The reduction in diesel consumption and improvement in fuel efficiency is expected to save over 2 million litres of diesel and over 5,500 tonnes of CO2 per year, every year, for at least the next seven years.”

SciDev and Iluka Resources take chemistry to the Max at Jacinth-Ambrosia

ASX-listed SciDev Ltd says it has been awarded a three-year contract with Iluka Resources for delivery of MaxiFlox® chemistry to the Jacinth–Ambrosia zircon mine, in South Australia.

The contract, expected to be worth some A$8-12 million ($5-8 million) over the three-year term, follows the delivery of a chemical products trial for the miner in the December quarter of 2018. This itself occurred following the announcement of a commercial OptiFlox® System test SciDev carried out.

MaxiFlox is specifically designed for use in solid liquid separation processes, SciDev says. Products in the MaxiFlox range are supplied in both liquid and powder form across an extensive range of molecular weights and charge densities to solve industrial challenges. Products include:

  • MaxiFlox organic liquid coagulants (based on synthetic organic monomers and naturally occurring polysaccharides);
  • MaxiFlox inorganic liquid coagulant blends;
  • MaxiFlox cationic and anionic flocculant emulsions;
  • MaxiFlox cationic and anionic flocculant powders;
  • MaxiFlox mud solidification polymers, and;
  • MaxiFlox antifoam products.

The technology can be used across a range of industries including mining and minerals processing, water and wastewater, oil and gas, food and beverage and paper manufacturing.

Iluka’s Jacinth-Ambrosia operation is the world’s largest zircon mine, according to the miner. Comprising two contiguous deposits, Jacinth and Ambrosia, the mine is around 800 km from Adelaide and 270 km from the Port of Thevenard.

The operation encompasses mining and wet concentration activities with heavy mineral concentrate transported to Iluka’s Narngulu mineral separation plant in Western Australia for final processing. Jacinth-Ambrosia can produce up to some 1,000 t/h of heavy mineral concentrate, which can produce up to ~300,000 t/y of zircon.
