JUWI says it has commissioned the world’s largest solar hybrid project at Centamin’s Sukari mine in Egypt, helping the gold miner save more than 20 million litres of diesel a year.

The system consists of a 36 MW solar farm and a 7.5 MW battery-energy storage system, which have been integrated into the existing diesel power station at the operation. This will provide savings of up to 70,000 liters of diesel per day, according to JUWI, resulting in an average reduction in diesel consumption of 22 million liters per year.

The system demonstrates the key role of renewable energies in decarbonising the resource sector and already delivers savings ahead of expectations, according to JUWI.

Centamin noted in October that it was in the final stages of commissioning the solar plant at the operation.

The solar system designed by JUWI has maximised the generation with bifacial solar photovoltaic modules and a single axis tracking system, taking advantage of the high irradiance on site. JUWI Hybrid IQ micro-grid technology enables the integration of the solar and battery system into the existing off-grid network and supports the operation of the existing power station, it says.

The additional benefits of the hybrid power solution at Sukari, according to JUWI, include lowering the site’s carbon emissions by an estimated 60,000 t CO2/y and a subsequent reduction in the volume of diesel trucked to the site, plus a reduction in operating costs

Stephan Hansen, COO and Managing Director of JUWI,said: “We are delighted to have been able to deliver this flagship project to Centamin and, furthermore, to have been able to demonstrate the vital role that dependable solar, wind and battery solutions can already play in the transformation of the resource sector on the de-carbonisation pathway.”

JUWI has already achieved success for mining clients globally with the world’s first utility scale solar battery hybrid project at the DeGrussa Copper mine in Australia. This was followed by Agnew Gold (Australia) in 2019 and another six hybrid projects in Australia and Africa for Tier 1 and Mid Tier miners: Esperance, Pan African Resources, Jacinth Ambrosia, Jabiru, Weipa and Gruyere.

Iluka taps into hybrid power at Jacinth-Ambrosia after KPS project completion

Pacific Energy says its subsidiary, KPS Power Generation, has completed the conversion of Iluka Resources’ 10 MW diesel power station at the Jacinth-Ambrosia mineral sands mine in South Australia to a hybrid power facility.

The “world first” hybrid power station incorporates both solar photovoltaics and electric turbo compounding (ETC) technology, combined with an upgraded control system, Pacific Energy said. ETC technology allows generators to maintain the same power output using less fuel and producing lower CO2 emissions, making generators work more cleanly and effectively by recovering waste energy.

The reduction in diesel consumption and improvement in fuel efficiency is expected to save over 2 million litres of diesel and over 5,500 t/y of CO2 at the operation, according to Pacific Energy.

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.

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

Shane Tilka, General Manager, Australian Operations at Iluka, said: “The move from diesel to hybrid energy at Jacinth-Ambrosia marks an important evolution in Iluka’s Australian operations. It also offers a potential blueprint for the future use of renewable energy at the company’s other existing and planned operations.”

Pacific Energy Group CEO, Jamie Cullen, said: “We are thrilled to work alongside Iluka, a valued long-term client to deliver a world-class, world-first solar PV and ETC hybrid power facility, and to assist them with reducing carbon emissions and transitioning to net-zero emissions.”

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.

  • 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.

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.
