Mining

Water is critical for all types of mining.
Calix can help simplify and reduce costs associated with acid water management.

Whether it’s the final process water, contaminated storm water or groundwater that is collected in an old mine pit; management of water quality for environmental discharge or recycling in the mineral extraction process is crucial for compliance with environmental regulations and continued operations of the mine site.

Industry challenges

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.

Mines around the world are facing increasingly stressed water supplies, but also increasingly stringent environmental regulations, encouraging them to turn to innovative wastewater treatment solutions that produce water suitable for reuse and limit environmental contamination.

Treating wastewater from mines has a dual potential benefit. Treated water can be recycled to help cut down freshwater use, while providing significant operational and cost benefits.

Neutralise acidic wastewater and remove heavy metals

ACTI-Mag is a highly active neutralising agent that can be used to treat acidic water for recycling or environmental discharge. The high surface area alkali also allows for the precipitation and removal of heavy metals without adding hardness to the water to reduce pipe scale.

Consequently, even very small improvements can translate into millions of dollars in savings over the life of a mining operation.

AWARD-WINNING SOLUTIONS FOR ACIDIC WASTEWATER RECYCLING AND ENVIRONMENTAL DISCHARGE

Our solutions are simple, cost-effective and can help existing wastewater treatment systems improve efficiency while significantly improve the quality of the wastewater discharge.

The process solution developed for each site is developed on a case by case basis as each site has different characteristics. Some of the areas where ACTI-Mag can provide significant benefits:

pH neutralisation of mine water

Safe and cost-effective alternative to caustic soda or lime

Reductions in heavy metals before environmental discharge

Treatment of mine sludge

Water recycling without scale

We work together in ways others don’t, considering the long-term effect of our actions, never satisfied with the status quo.

Calix has its own direct delivery, service and support capabilities and also has an established a network of local distributors and partners that can provide the best solution for your specific needs and ensure you receive excellent customer service and support, wherever you are located.

THE CALIX DIFFERENCE

Calix core technology makes high surface area materials (with a honeycomb-like structure), giving you a price and a reactivity advantage.

Our materials are proving to have similar properties to highly active nano-materials, without the health/safety concerns and high cost, but with all the benefits.

Faster reactivity = less costs

MANUFACTURED IN AUSTRALIA

Fully integrated supply chain – from mine to customer

Calix is able to offer better service, reliability and performance to its
customers because it controls the entire production process from mining
of raw materials, processing and production.
