Rheology Modifiers for Slurry Transportation & Gold Leaching

In modern mining, high-viscosity slurries create significant operational hurdles from astronomical pumping costs and water scarcity to inhibited chemical reactions in leaching circuits. FLOMIN™ RMA is an advanced rheology modifier specifically engineered to reduce yield stress and optimize pulp flow, transforming these challenges into strategic advantages

Product Overview
What is FLOMIN™ RMA designed for?

FLOMIN™ RMA is a rheology‑modifying agent engineered to reduce slurry viscosity and yield stress in demanding mining environments. By altering the internal structure of ore and tailings slurries, it promotes smoother flow, greater transport efficiency, and more stable process conditions—especially in high‑solids operations.

In hydrometallurgical circuits, FLOMIN™ RMA improves the chemical and physical environment inside cyanide leaching tanks by preventing fine‑particle agglomeration and reducing slime coatings. This enhances the contact between cyanide and gold, increases oxygen dispersion, and supports more complete dissolution even in difficult, clay‑rich or viscous ores.
Through its combined effects on flow, mixing, dispersion and particle behavior, FLOMIN™ RMA helps mining operations reduce energy consumption, improve metallurgical reactions and stabilize overall process performance.
Key Benefits
Operational impact
Reduces slurry yield stress to ensure smoother flowability and more consistent pulp movement across long distances.
Enables the transport of higher solids concentrations, significantly reducing fresh water usage and dilution requirements.
Optimizes pumping efficiency to lower energy demand while simultaneously reducing mechanical wear on pipelines.
Improves slurry rheology to facilitate superior mixing and prevents "slime" coatings from hindering cyanide-gold contact.
Enhances oxygen availability through more effective air dispersion throughout the pulp for faster and more complete dissolution.
Mitigates the effects of preg-robbing ores by ensuring dissolved gold remains accessible to activated carbon rather than being lost to gangue minerals.
Application
Where / How FLOMIN™ RMA is typically used

FLOMIN™ RMA is used across mining circuits where slurry rheology affects pumping efficiency, solids handling, or gold extraction performance.

Long‑Distance Slurry & Tailings Transport
By lowering yield stress and improving particle dispersion, RMA enables stable high‑solids transportation over long distances with less friction, lower pumping energy, improved water efficiency and more reliable plant performance.
CIL/CIP Cyanide Leaching Circuits
In leaching tanks, FLOMIN™ RMA enhances cyanide–gold contact and increases oxygen availability by reducing viscosity and preventing slime or clay coatings. This minimizes preg‑robbing effects, improves mixing uniformity, and supports faster and more complete gold dissolution.
Together, these applications allow mining operations to handle denser slurries, reduce operational bottlenecks, and increase metallurgical efficiency across both transport and extraction stages.

Frequently Asked Questions
Everything you need to know about FLOMIN™ RMA

While not a chemical blinding agent, FLOMIN™ RMA optimizes the physical environment of the leach. By reducing slurry viscosity and preventing fine "slimes" from coating the ore, it ensures that dissolved gold and reagents can move freely through the pulp. This improved mobility and superior mixing allow the added activated carbon to compete more effectively for gold adsorption, reducing the window of opportunity for carbonaceous gangue to "rob" the gold from the solution.

Yes, this is one of the primary mechanical advantages of the product. By reducing the yield stress and lowering the internal friction of the pulp, FLOMIN™ RMA allows for the transport of higher solids concentrations while maintaining—or even reducing—the required pumping energy. This enables operators to significantly increase throughput and plant performance without the massive capital expenditure (CAPEX) required for new pumps or pipelines.

No, FLOMIN™ RMA is engineered to be fully compatible with standard mineral processing reagents and existing process conditions. It is designed to work immediately upon contact with the slurry without causing adverse chemical reactions. In many cases, it actually improves reagent utilization by ensuring better cyanide and oxygen distribution, as it eliminates the high-viscosity "dead zones" that typically hinder reagent penetration.

To achieve the best results, FLOMIN™ RMA should be added where the slurry is first conditioned or where rheological constraints begin. Typical dosage points include the mill feed or the leach/leach-conditioning tanks. Because the product modifies rheology instantly, adding it early in the circuit ensures that the benefits—such as improved mixing and reduced agitation load—are realized throughout the entire leaching or transport process.

FLOMIN™ RMA is a strategic tool for water conservation because it enables the transport of "thicker" slurries with significantly less dilution water. By reducing the amount of fresh water needed to move tailings or ore over long distances, mines can decrease their overall environmental footprint. This not only supports environmental compliance but also reduces the energy required for water recovery and tailings management.

No. While they share the FLOMIN™ RMA brand name because both optimize rheology, they are distinctly different chemistries. The RMA formulation for pulp transport is engineered to withstand high shear forces and provide long-term stability across kilometers of pipeline to lower yield stress and pumping costs. In contrast, the RMA for cyanide leaching is a specialized formulation designed to remain chemically stable in high-pH environments and optimize gas-liquid-solid mixing without interfering with gold adsorption kinetics. By using application-specific polymers rather than generic dispersants, we ensure maximum efficiency for each unique circuit.
