transfer oxygen into the ILS , PLS & Raffinate Solution.

ARS Nanobubble generators play a crucial role in heap leaching, an industrial mining process used to extract valuable metals and compounds from ores. These generators produce a high density of tiny bubbles, known as nanobubbles, which are injected into the leaching solution.

Nanobubble Generator is the most efficient aeration technology to transfer virtually any gas into any solution liquid. The Nanobubble generator produces trillions of Nanobubbles, ~100nm in size.

The ARS Nanobubbles significantly increase the surface area available for chemical reactions, accelerating the leaching process and improving the extraction efficiency.

By optimizing oxygen levels and enhancing mass transfer, ARS Nanobubble technology offers numerous advantages in heap leaching operations.

How? Fe2+ changes to Fe3+ and its effects, The conversion of Fe2+ to Fe3+ is a fundamental concept in redox reactions and plays a crucial role in numerous chemical and biological processes.

When the Zeta potential of Nano bubbles and ore particles are opposite in charge, electrostatic attraction occurs. This interaction increases the likelihood of Nano bubbles attaching to the surface of the ore. As a result, the contact time between the leaching solution and the ore is extended, improving the efficiency of metal dissolution.

Enhanced Oxidation: Fe²⁺ to Fe³⁺ ,Accelerating redox reactions, particularly Fe²⁺ to Fe³⁺ regeneration.

During the leaching process, Fe³⁺ ions act as strong oxidizing agents, especially for refractory ores like chalcopyrite. As Fe³⁺ oxidizes the metal, it is reduced to Fe²⁺, which needs to be reoxidized back to Fe³⁺ to sustain the leaching cycle.

Nano bubbles play a key role in this redox regeneration by:

•Providing a high surface area for oxygen transfer.

•Enhancing oxygen dissolution in the leach solution

Accelerating redox reactions, particularly Fe²⁺ to Fe³⁺ regeneration

•Possibly generating reactive oxygen species (ROS) that accelerate Fe²⁺ oxidation.

The presence of nano bubbles therefore promotes faster and more efficient oxidation of Fe²⁺ to Fe³⁺, maintaining high oxidizing potential in the system.

The ARS Nanobubble generator transfers Oxygen with greater than 90% efficiency, providing maximum utilization potential, improving the functionality of heap leaching solution , and enhancing the recovery processes. ARS nanobubbles remain in suspension after saturation, creating a reserve of available oxygen/gas in the irrigation system-solution for heap leaching method.

Installing the right irrigation system is one of the most important elements in the process which affects the permeability and the uniformity percolation all over the pad.

With ARS technology system we ensure to control the flow rate m2 and the amount of dissolved oxygen . The ratio of oxygen during the leaching is the most important and critical aspect for the ore by controlling the percolation and the oxygen in to the leaching ore .

With ARS Nanobubble Generator we control and inject the right amount of oxygen during the leaching process.
