Main Products

• Aachen High Shear Reactors For Increased Gold And Silver Recovery

The Aachen Reactor is a high-efficiency mass transfer device developed from Maelgwyn’s experience in Imhoflot flotation technology. The unit can be used in any application requiring thorough gas–liquid mixing but is particularly suitable for gold and silver leach applications where increased dissolved oxygen levels before or during leaching are needed. Historically, many operations have worked to increase dissolved oxygen in leach tanks using various methods of air and/or oxygen injection, but large oxygen bubbles quickly rise and exit the tank, making the process inefficient and oxygen-intensive. The second drawback of such systems is their failure to address surface passivation caused by oxidized species that can slow the leaching reaction. In contrast, the Aachen High Shear Reactor can generate significantly higher dissolved oxygen levels while using high shear forces to scrub mineral surfaces. The net benefits include:
- Higher gold recovery/lower tail grades
- Accelerated leach kinetics
- Reduced cyanide consumption
- Improved oxygen utilization
- Increased throughput without compromising recovery

• Maelgwyn Imhoflot Advanced Reactor Flotation

Imhoflot pneumatic flotation technology has evolved through 25 years of industrial application, leading to the patented Imhoflot G-Cell. The cell uses centrifugal forces generated as the mineral slurry enters to rapidly recover minerals and allows for much smaller cell volumes and flotation plant footprints.
Features of Imhoflot:
- High selectivity in grade-recovery relationship due to very small bubble sizes and high energy in the reactor
- Effective recovery of fine (<20 µm) and coarse (>350 µm) particles when tank flotation is inefficient
- Small cell volumes and compact flotation plant footprint
- No moving internal parts
- Lower energy requirements since no rotor/stator is needed to suspend slurry
Operational Design Features & Benefits:
- The Imhoflot pneumatic flotation process concept yields higher recoveries with extremely low residence time.
- Imhoflot is characterized by high unit throughput and tolerance to wide variations in feed rate and grade.
- It can handle widely fluctuating feed conditions and recover slow-floating minerals, reducing both capital and operating costs.
- Slurry is aerated via a centrifugal pump that provides energy for thorough air–slurry mixing, yet specific power consumption is typically less than 60% of conventional rotor-stator cells.
- Required footprint is much smaller compared to other flotation systems.
- High selectivity between ore and gangue simplifies process flowsheets.
- Modular process design.
- Distribution unit, aeration unit, and separation cell design enable easy assembly and replacement of parts.

• Leachox™ Process For Flotation Concentrates

Aachen Reactors form an integral part of the Leachox process for treating gold-bearing sulfide flotation concentrates. These concentrates are often refractory to cyanide or have gold locked in pyrite or arsenopyrite, requiring very high reagent additions for adequate recovery.
The Leachox™ process comprises several interlinked Maelgwyn proprietary processes, including:
- Imhoflot G-Cell flotation
- Ultra-fine grinding using the Ro-Star mill
- Aachen Reactors
- Reactor-assisted cyanide destruction
- Ultra-fine grinding to liberate sulfide minerals as a unit operation in the Leachox process

Diemme Filtration

Diemme® was born in the early 1970s when the filter press moved beyond its traditional applications in the food industry and established itself as a process technology for solid–liquid separation in other industrial sectors. At that time, the filter press became the machine of choice for treating industrial and municipal sewage sludge, and today it continues to serve in all applications such as mining and chemical industries, power plants, oil and gas. It serves industries where high dewatering performance, low operating costs, and reliability are key factors in technology selection. Diemme® Filtration has the widest range of filters available globally in terms of size, design, and technical features. Equipment is custom designed and manufactured to suit application needs. Diemme® Filtration has also begun designing and supplying its own range of high-rate thickeners, expanding its supply scope and offering greater support to customers.

Products:

• Filter Presses

Diemme Filtration has captured a large market share in the solid–liquid filtration segment due to its ability to customize systems entirely to customer requirements. Diemme® Filtration filter presses vary in plate transport design (top or side transport), plate size, and automation level. Plate size depends on the dimensions and number of plates fitted. Diemme® Filtration plates are available in different nominal sizes (from 500 × 500 mm to 5 000 × 5 000 mm), various materials (polypropylene, carbon, PVDF, etc.), and process configurations (membrane and recessed plates).
Automation levels:
- Semi-automatic, where the operator intervenes in various stages of the filtration cycle,
- Automatic, operating with the operator in a supervisory role,
- Fully automatic, running continuous filtration cycles without any personnel intervention.
Models:
- GHT-F
- GHT5000F DOMINO
- GHT-P
- GHS
- ME
- AUTOMAT
- KE

• Thickeners / Clarifiers

Slurry Thickeners: Diemme® Filtration high-rate thickeners are the result of decades of experience in solid–liquid separation across mining, chemical, metallurgy, water treatment, and many other industries. Our commitment to R&D enables us to propose innovative solutions to optimize performance and reduce plant costs.

Strengths of Diemme® Filtration:
- Comprehensive laboratory testing on customer samples (selection and dosing of flocculants and coagulants, static and dynamic tests, rheology, mineralogy, etc.);
- Mechanical parts designed for the most demanding conditions to ensure long-term performance and reliability;
- Optimization of tank structural design (static and dynamic analysis, seismic, FEM modeling, weight optimization, etc.);
- Integration of instrumentation and control tools to optimize processes and reduce operating costs;
- IIoT connectivity;
- Comprehensive and customizable premium components;
- Global service support.
Diemme® Filtration high-rate thickeners deliver very high efficiency and are designed to complement Diemme® Filtration filter presses. Thickeners can be manufactured in diameters of 40 m and above, available in “Bridge” or “Column” versions. Depending on project specifications, they can be built entirely from carbon steel, stainless steel (with or without rubber lining), or as concrete tanks. From a process perspective, clarifier performance depends on the system’s ability to bind solids to flocculant. This occurs in the feed well at the heart of the clarifier. The incoming stream in the feed well provides mixing energy for floc formation and subsequent settling to the tank bottom. The complex design, requiring CFD modeling by Diemme® Filtration’s technical staff, results in optimized flocculant consumption, high supernatant clarity, and consistent thickened slurry density.

Gekko

At Gekko we believe in collaboration. We work “Smarter Together” with our mission to “transform mining and the environment”. As a company we have invested the time of over sixty of our outstanding people to better understand what makes us tick. …what we believe in and what drives us to be world’s best. What we discovered is that our team is passionate about transforming mining and the environment for the better and that working collaboratively is necessary to achieve our goals and those of our partners. This is how our full Gekko Systems corporate manifesto or belief was born
Gekko Manifesto: Belief.
“Only by embracing smart ideas together can we transform our world.”
We have summarised this belief in our tag line “smarter together”. It seems obvious to us that to achieve meaningful change, we have to work together.
Gekko was founded in 1996 in Victoria, Australia. Gekko began producing In-Line Pressure Jigs for continuous gravity separation. However, growing demand for energy-efficient devices prompted Gekko to rethink and develop traditional processing flowsheets. Innovative modular designs, elegant systems, and smart manufacturing have made Gekko the world technical leader in gold processing and low-energy mining solutions.
