Calix’s patented core platform technology uses indirect radiative heating to efficiently process raw minerals into low carbon mineral products. Efficient and precise electric heating, fully compatible with renewable energy sources, replaces inefficient combustion of fossil fuels.
For green iron and steel, electric heating is paired with hydrogen as a reducing agent to replace coal. No blast furnaces. No emissions.
Processing minerals at the mine site can also offer a new paradigm in sustainable mineral production, including enhanced ore recovery, fewer processing steps, zero-waste, rationalised supply chains, and reduced transport costs.
With solutions designed for the world’s most essential and carbon-intensive industries, Calix is pioneering sustainable processing for the electric age.
The iron and steel industry is often regarded as one of the world’s hardest-to-abate. It accounts for around 7% of global carbon dioxide emissions, with over 80% of these emissions being a result of the conversion of iron ore to metal iron.
Similarly, the production of aluminium, an important material for many technologies, is amongst the most energy-intensive of industrial processes, contributing about 2% of global CO2 emissions. Demand for lithium and other critical minerals required to underpin the energy transition is expected to grow dramatically over the next decade.
By combining mineral and renewable energy resources – and utilising innovative enabling technologies – mineral producers have the opportunity to deliver premium low-carbon mineral products critical to global decarbonisation and sustainable development goals.
Calix’s innovative electric calcination technology enables mineral producers to deliver sustainable mineral products to the world.
By enabling the use of renewable energy, delivering clean and precise electric heating, and enabling the most efficient use possible of green hydrogen, Calix’s technology aims to deliver the lowest cost decarbonisation solution for green iron and steel, green alumina, sustainable lithium, and other critical minerals.
Electrification is a key enabling technology for mineral processing to replace fossil fuel combustion with renewable energy use, decoupling inherently energy-intensive processes from carbon-intensive products. Calix’s electric calciner can reduce carbon emissions by up to 90% relative to conventional fossil fuel powered rotary kilns.
The precision enabled by electrification and indirect heating can deliver more efficient and controlled mineral processing, reducing energy consumption and enabling greater utilisation of the mineral resource.
Processing minerals at the mine site replaces the transport of low purity ores for high purity mineral products. Waste can be avoided or returned to its origins, providing significant environmental and economic benefits over current practices. End users can simplify, de-risk and decarbonise the route that minerals take to reach them.
At-mine processing may be particularly beneficial for remote mining operations or for unlocking mineral assets with limited transport infrastructure.
Calix’s innovative mineral processing solutions can eliminate processing steps and requirements, such as the pelletisation of iron ore fines or the use of fluidised beds, to avoid significant capital and energy costs and simplify operations.
Calix’s sustainable processing technology has the potential to provide a versatile grid-load balancing service to the energy grid. It is designed to be compatible with intermittent and renewable sources of electricity, and capable of matching its energy use to the energy grid’s requirements across a wide range.
Demand side load balancing – analogous and complementary to supply side energy storage – could support further renewable energy integration into the grid, lowering grid balancing costs, and potentially enabling more economical industrial energy use.
Calix’s unique indirect heating approach ensures that hydrogen is used only as a reductant in the production of green iron and steel. Hydrogen is not combusted or used as a fuel, and unreacted hydrogen is simply recycled.
Calix’s modular technology can be simply scaled through duplication, de-risking technology scale up and enabling flexible production volumes.
Processing minerals at the mine site with locally produced renewable electricity has the potential to reduce costs and capture more value from the mineral resource.
Additionally, producers can create value through premium, decarbonised mineral products as carbon pricing mechanisms and carbon border taxes become more prevalent.
Commercialisation
To reach the Sustainable Development Goals, industries that traditionally rely on carbon intensive heating sources and feedstocks must become compatible with clean alternatives.
Calix’s electric calcination technology provides a sustainable and economical pathway for industrial processes to transition to renewable energy sources.
Through strong global partnerships and collaboration with industry, academia and governments, Calix is accelerating the development and commercialisation of its core platform technology to urgently solve some of humanity’s greatest challenges. We recognise and thank each of our partners for their vital contributions.
