Comminution Design

Comminution is the most energy intensive and costly component of mineral processing.

Improving how comminution, the crushing and grinding of material to a smaller size, is executed and managed is instrumental to Gekko’s global expertise in energy-efficient flowsheet design.

Gekko’s focus is to process ore that has optimal liberation through pre-concentration or gangue rejection. Therefore, employing the right device, to produce the right size ready for the next process step, is important.

Comminution design innovations dramatically reduce energy costs.


There are many environmentally friendly, energy-saving benefits associated with eco-efficient comminution strategies.

Coarse particle size for mineral liberation improves operations and enhances the whole processing flowsheet.

An energy-efficient comminution design leads to reduced operating expenses and enhanced revenue.

Modular low-footprint components provide speed-to-operation for improved, faster recoveries.

Gekko’s laboratory services offer ongoing technical support and expertise to optimise comminution strategies.

Fine crushing to a small particle size saves on energy that milling would normally require.

How It Works

Comminution, the simple crushing and grinding of ore to reduce its size, can be performed by a series of innovative devices to provide a coarse particle size that exhibits optimal mineral liberation.

There are various types of comminution design. Advanced engineering and research have identified improved designs and devices that can lower operational costs and reduce energy consumption.

To achieve an optimal flowsheet design, each ore deposit needs to be tested, to identify its unique comminution characteristics. Then a comminution strategy can be devised to complement and maximise the overall recovery approach.

The Gekko Difference

Gekko is passionate about finding better ways to perform comminution, so much so that Gekko have established a not-for-profit educational organisation called the Coalition for Eco-Efficient Comminution (CEEC). This organisation is supported by a broad range of mining sector companies with the common goal to accelerate awareness, knowledge transfer and, as a result, improve energy and cost outcomes in the substantive area of comminution.

Historically, traditional crushers and jigs use vast amounts of energy that, over the entire mineral processing operation, are expensive and inefficient to operate.

Gekko’s core technologies, the InLine Pressure Jig and the Python processing plant play a key role in producing energy-efficient comminution flowsheets. Coarse liberation of minerals at the start of the process reduces energy input and this has flow-on effects for energy savings during downstream processing. The type of comminution device employed by a mining operation is extremely important for minimising energy costs and maximising profits.

The modular design and clever construction of the InLine Pressure Jig and Python processing plant components provide exceptional speed-to-operation for fast financial returns, as well as energy-efficient and environmentally friendly processes.

Gekko’s technical services team will perform extensive testwork on an ore body to understand its mineralogy and comminution characteristics. Then Gekko will recommend and design the optimum comminution flowsheet to deliver maximum mineral liberation. For more information, contact Gekko’s technical services team today.
