The Sinoz Group
Reliability, Resiliance, and Relationships in Mineral Processing

For over a quarter of a century, The Sinoz Group has steadily built a reputation as one of the mineral processing industry’s most dependable partners.

Founded in 1997 and headquartered in Port Melbourne, Victoria, Australia, the company has grown into a leading specialist in flotation reagents, supplying over 100 mine sites globally. From base metals to precious and critical minerals, its clients include major global mining houses, mid-tier producers, and ambitious junior mining companies.

What unites them is a shared trust in The Sinoz Group’s unwavering commitment to performance, reliability, and value.

At the core of that trust is focus. Unlike many chemical distributors that operate as broad-spectrum vendors, The Sinoz Group has maintained a deep specialization in mineral flotation reagents. This singular focus allows the company to offer an unmatched level of technical expertise, logistical agility, and supply consistency. Its three operating entities—Sinoz Chemicals and Commodities Pty Ltd, Kanins International Pty Ltd, and Kemtec Mineral Processing Pty Ltd—form a vertically integrated ecosystem built to deliver tailored reagent solutions with precision.

Sinoz Chemicals and Commodities anchors this ecosystem with its manufacturing capabilities, producing a full range of high-quality flotation collectors at its state-of-the-art facilities in Shandong Province, China. This direct control over production gives the company the flexibility to respond swiftly to client needs while maintaining rigorous quality standards.

Kanins International complements this by sourcing auxiliary reagents such as mineral salts, activated carbon, and processing aids under long-term supply agreements. These supply chains are not only robust but also certified for safety and sustainability. Kanins International has successfully broadened many of its reagents and systems for demanding new markets such as animal feed. To this end, it maintains FAMI-QS certification.

While Sinoz Chemicals and Commodities and Kanins International secure the materials, Kemtec Mineral Processing brings application expertise to the forefront. Kemtec is the company’s technical arm, working closely with clients to design, trial, and optimize reagent formulations tailored to specific mineralogies and plant conditions.

“We view flotation as one of the most critical industrial nanotechnologies—an elegant and powerful process that enables the selective recovery of valuable minerals,” says Simone Watt, CEO and Managing Director of The Sinoz Group.

This perspective shapes the company’s philosophy: flotation reagents are not commodities, but finely tuned tools that require deep application insight and in-field support.

Each reagent—whether a collector, activator, depressant, or pH modifier—plays a distinct role in the flotation process. Collectors such as thionocarbamates and xanthogen formates enhance the hydrophobicity of target minerals. Activators modify mineral surfaces to improve collector performance, while depressants selectively suppress unwanted gangue minerals to improve concentrate grades. pH modifiers help control pulp chemistry, enabling the optimal environment for reagent interaction. But the magic lies in their interplay. These reagents exhibit non-linear behaviour, and their effectiveness depends on how well they are matched to the hydrodynamic conditions of a specific circuit.

The Sinoz Group’s approach begins with thorough site consultation, involving metallurgists and plant operators from the outset. Hydrodynamic modelling, laboratory test work, and on-site trials form the foundation of each solution. This isn’t theoretical tinkering—it’s hands-on science, executed with the kind of pragmatism that only comes with real-world experience. Many of the company’s technical experts have worked in processing plants themselves, and that operational insight informs every engagement. The result is a tailored formulation, backed by structured implementation and ongoing performance tracking.

What further sets The Sinoz Group apart is its operational discipline. In more than 25 years of business, the company has never allowed a customer to run out of stock. This remarkable record is the result of a deeply embedded culture of planning, responsiveness, and resilience. Weekly and monthly reviews with client sites ensure that supply plans are continuously adjusted. Inventory is managed through min/max systems and reinforced with multi-tiered contingency strategies. The company’s robust logistics network allows for rapid redirection of materials when conditions change unexpectedly.

Innovation is central to The Sinoz Group’s story. The company’s research and development efforts are grounded in real-world application. Rather than developing chemistry in a vacuum, The Sinoz Group invests in trials that consider variables such as seasonal water chemistry changes and evolving ore bodies. One recent success involved helping a client adapt their reagent program to shifts in water composition using a combination of laboratory and plant test work to fine-tune frother dosing. The result was a tangible improvement in flotation efficiency, concentrate quality, and operational predictability.

Sustainability is more than an aspiration at The Sinoz Group—it is embedded in its operations. The company actively supports clients involved in tailings reprocessing, a growing trend aimed at extracting additional value from legacy waste. Environmentally responsible packaging, concentrated product formulations, and adherence to international safety standards further underscore its commitment to responsible practices. The Sinoz Group is continually exploring ways to reduce its carbon footprint by committing to clean energy, selecting partners who optimize supply chains, and adopting new technologies.

With a majority-female workforce and a female CEO at the helm, The Sinoz Group also champions workplace diversity as a driver of resilience and innovation. The company supports local social initiatives such as Indigenous mental health and women’s empowerment programs in Papua New Guinea, including upskilling women for value-added fishing activities.

Quality is non-negotiable. The company employs a risk-based approach to quality management, conducting regular production and packaging audits. Reagents that don’t meet specifications are rejected or reworked. Brand integrity is paramount, and products are never manufactured to meet a price point at the expense of performance. Instead, The Sinoz Group positions its reagents as value creators—enabling efficient mineral recovery and improved plant outcomes.
