Solutions for the mining and mineral processing industry

Calix can help simplify and reduce costs associated with sustainability of existing processes, through CO2 reduction, increased use of mineral resources or water management.


Now, as industries and governments around the world look for ways to reduce carbon output and environmental impact, mining and mineral processing is taking a serious look at how it can reduce environmental impact and make its practices more sustainable.

Mining challenges today

Mining industries provide most of the materials we rely on to build infrastructures, to obtain large amounts of energy, or to supply agriculture with fertilisers that help feed a growing population. Yet mining and mineral processing uses significant amounts of resources — water, land, carbon and energy — and often causes severe harm to the environment.

Current mining practices need to change and  protect better natural resources and ecosystems, in order to be environmentally acceptable and compliant with sustainable development objectives.

Our Solutions

A leading-edge sustainable process

At the core of Calix’s diverse and versatile innovations is a pioneering technology that re-imagines the calcination process, enabling new applications and materials that solve global challenges.

Calix technology also allows for the direct separation of CO2, allowing it to be used for carbon dioxide reduction in traditionally carbon dioxide intensive industries, such mineral and chemical processing.

ACTI-Mag, for neutralisation of acidic wastewater and removal of heavy metals

Mines produce a complex wastewater effluent, often difficult to treat due to its high levels of dissolved minerals and heavy loading of contaminants that can make it difficult to discharge or to recycle. Even very small improvements can translate into millions of dollars in savings over the life of a mining operation.

  • pH neutralisation of mine water
  • Reductions in heavy metals before environmental discharge
  • Water recycling without scale
  • Safe and cost-effective alternative to caustic soda or lime
  • Treatment of mine sludge
