Heap leaching is an industrial mining process used to extract precious metals, copper, uranium, and other compounds from ore via a series of chemical reactions that absorb specific minerals and then re-separate them after their division from other earth materials. Oxygen plays a critical role in enabling these reactions; however, efficiently delivering oxygen into the leaching process is challenging. Moleaer's proprietary gas-injection technology overcomes this challenge by plugging directly into the leaching irrigation system. In many cases, the generators can be added without the need for an additional pump. This simple plug-and-play solution combined with the ability of Moleaer's nanobubbles to significantly increase and maintain elevated dissolved oxygen (DO) levels in leaching solutions provides miners with the opportunity to increase metal recovery or lower their leaching costs.
