Axis House Group, a leading reagent manufacturer and supplier to the mineral processing sector, has made a significant commitment to sustainability by dedicating research and development efforts to the development of environmentally friendly reagents. Concrete initiatives, including gold leaching without cyanide and a range of non-hazardous frothers, allow the Axis House Research and Development team to reduce the environmental impact of its products, plus showcase and drive positive change within the industry.
Mining has long been a critical industry for global development, providing essential resources for various sectors. The escalating demand for battery metals, driven primarily by the rise of EVs and renewable energy technologies, has positioned countries with significant reserves of these metals at the forefront of economic opportunities. The surge in demand presents challenges and opportunities, emphasising the importance of holistic solutions that balance economic benefits with environmental and social responsibility.
This urgent need for developing sustainable and responsible supply chains for mining and processing these metals underscores the urgency of investing in research and development (R&D) for alternative technologies. This involves reducing reliance on hazardous chemicals, finding greener solutions, and exploring innovative approaches to mineral processing. Axis House, with its dedicated R&D team, is at the forefront of these efforts, actively working to reduce the environmental footprint of its products and contribute to the industry’s sustainable future.
One major initiative by Axis House involves the development of non-hazardous alternatives for cyanide salts, specifically in polymetallic flotation. Revadep 150 and Revadep 226 are both cyanide-free and non-hazardous depressants. The elimination of cyanide from the process promises a substantial impact on logistics, storage, and the environment. It also ensures improved health and safety, and a significant reduction in operating costs.
Another groundbreaking initiative by Axis House is the introduction of D20-M3, a non/low-hazardous alternative to cyanide in gold leaching applications. This innovative leaching agent boasts similar leach kinetics as cyanide while producing effluent that requires minimal to no treatment.
Also on the green agenda for responsible mineral process is Axis House’s focus on promoting safety in sulphide collectors, advocating for the use of liquid sulphide collectors with lower hazards when compared to traditional options such as xanthates. In addition, sustainable initiatives also encompass organic polymer depressants widely used for talc, carbon, pyrite, and other floatable gangue. These depressants are safe to use and environmentally friendly and sustainably produced.
The company’s commitment to sustainability extends to its innovative frothers range. The high flash point Hydrofroth frother range ensures operational safety while aligning with responsible mineral processing practices. On-site customisation of frothers further reduces hazards and improves process efficiency.
Finally, Axis House recognises the critical role of water treatment in enhancing the overall sustainability of mineral processing operations. Implementing advanced water treatment processes not only minimises the environmental impact but also contributes to improved water conservation and reduced demand on local water sources. Treating water with the Bronte flocculants and dewatering range facilitates efficient recycling within processing plants.
With a focus on the entire mining value chain, Axis House’s specialist teams offer tailored solutions, modifying reagent suites and dosages to optimise specific plants or situations. Beyond chemical solutions, the company provides a full supply chain service, including off-balance sheet stock holding, new routes to market, and innovative storage solutions.
As pressure on metal prices intensifies, Axis House recognises the importance of improving processes to save money for clients. Its strategy to reduce the quantity of chemicals in mineral processing aligns with a holistic view of the entire value chain. By emphasising the importance of optimised dosages, the company aims to lower its carbon footprint and that of its clients. With an increasing number of clients seeking ways to improve processes and save money, Axis House is experiencing growth in demand for technical support, both locally and in the territories in which it operates.
Customisation is a key aspect of Axis House’s approach when working with clients. The company obtains ore samples, and the metallurgical processing team creates tailor-made solutions in its Cape Town laboratory. Recognising the ever-changing nature of ore bodies, Axis House adapts its reagent suite for each unique situation, ensuring maximum economic efficiency for clients.
Looking ahead; the years leading up to 2030 represent a critical period in which the demand for battery metals will reach unprecedented levels. The industry must navigate this surge with a holistic approach, addressing not only the economic opportunities but also the environmental and social responsibilities associated with increased mining activities.
The surge in demand for battery metals highlights the urgency of investing in research and development for alternative technologies, and Axis House showcases a commitment to green solutions that improves operational efficiencies and contributes to a safer, healthier, and more environmentally friendly future for mineral processing paving the way for a sustainable tomorrow.
