​​Rock Kleen Tailings Recovery Process - A revolutionary partnership with Auric Gold & Minerals

Auric is positioned to capitalize on Itronics Zero Waste Energy Saving Technologies (Rock Kleen), which will be instrumental in the design and development of the project at Fulstone (or essentially any mine).  Itronics ‘Green Mining’ philosophy targets 100% beneficial use of a given resource, while at the same time, minimizing energy consumption and improving the environment. Itronics and Auric are positioned to answer the call of environmentally conscious investment funds and individual investors who demand a more thoughtful approach to metal and mineral extraction and recovery. Itronics believes that its approach to green mining will benefit shareholders and stakeholders alike, not only in terms of a clean approach, but also a profitable one.

What is Rock Kleen?

Rock Kleen is a revolutionary, disruptive technology that recovers residual precious metals, base and ferrous metals, nutrient materials, and industrial minerals from ‘sub-ore grade’ mine tailings. Nevada silver/gold tailings are the primary target for Rock Kleen; Copper tailings are a possible secondary recovery target. Rock Kleen breaks down and eliminates residual cyanide,  sulfuric acid, and recovers blasting nitrates used in original mining, thereby rendering tailings clean, just as nature intended.

Rock Kleen is a Deep Eutectic Solvent (D.E.S.)

Rock Kleen Liquid, a Deep Eutectic Solvent developed by Itronics Inc., is a fertilizer prodoct that has been repurposed to process mine tailings. Deep Eutectic Solvents (D.E.S.) are mixtures of two or more components that combine to form a liquid with unique properties.  They are often considered to be "green" solvents because they are typically non-toxic and biodegradable.

Who developed Rock Kleen?

​Rock Kleen is a technology developed by Itronics, Inc., specifically aimed at addressing the environmental issues and resource recovery challenges associated with leftover mine tailings. Here's a breakdown of its key aspects:

  • Rock Kleen is a “green” Deep Eutectic Solvent (D.E.S.)
  • Rock Kleen is a low energy process.
  • Rock Kleen recovers precious metals, base and ferrous metals
  • Rock Kleen recovers industrial minerals including crushed rock, crushed sand, clays, and mineral nutrients 
  • Rock Kleen’s chemistry can be adapted to target specific metals and mineral nutrients
  • The Rock Kleen model targets making 100% of tailings salable products
  • Rock Kleen is energy saving as it uses a waste product, tailings, to produce products that are primarily mined in other locations, saving the energy required to mine and crush this additional rock for the same products. 
  • Rock Kleen eliminates residual cyanide by breaking it down into its components, carbon and nitrogen, then recovers the nitrogen
  • Rock Kleen breaks down residual nitrates left by blasting the rock and recovers the nitrogen
  • Rock Kleen dilutes residual sulfuric acid and recovers the sulfur

​What are Mine Tailings?


Before diving into Rock Kleen, it's important to understand mine tailings. These are essentially the leftover materials after the targeted valuable minerals (like gold, silver, or copper) have been extracted from mined rock. These tailings can be vast and pose environmental challenges due to residual chemicals and potentially useful minerals.​

Why is Cyanide used in Mining Operations?

Cyanide is used in gold mining for its ability to dissolve gold, making the extraction process efficient. It's important to remember that cyanide's toxicity necessitates strict regulations and careful handling during gold mining operations.

Rock Kleen's Disruptive Approach to Mine Tailings and Cyanide Use:

Rock Kleen tackles these tailings piles with a revolutionary approach. It's a liquid solution that utilizes a special chemistry called Deep Eutectic Solvent (DES). This DES solution has the unique ability to dissolve and separate various components from the tailings. and render cyanide inert (chemically inactive).

What Rock Kleen Does:

  • Recovers Residual Metals: The solution can extract any remaining precious metals like gold, silver, and even base metals that might be present in the tailings. This prevents these valuable resources from going to waste.
  • Recovers Residual Nutrients: Rock Kleen also recovers valuable nutrients like nitrogen and potassium from the tailings. These can be used as raw materials for fertilizers, promoting resource recovery and reducing reliance on virgin materials.
  • Recovers Industrial Minerals: The process can also recover usable industrial minerals from the tailings [2]. This expands the potential uses of the leftover materials.
  • Neutralizes Harmful Chemicals: It can neutralize harmful chemicals often present in tailings, such as residual cyanide or sulfuric acid used in the mining process. This significantly improves the environmental impact of these tailings piles.

Benefits of Rock Kleen:

  • Promotes Sustainability: By recovering valuable resources and cleaning up tailings, Rock Kleen promotes a more sustainable approach to mining. It minimizes waste and environmental damage.
  • Maximizes Resource Use: The technology aims to achieve 100% beneficial use of the tailings, eliminating the need for long-term storage facilities and the associated environmental risks [5].
  • Economic Potential: By recovering valuable metals and minerals, Rock Kleen can create new economic opportunities from what were previously considered waste materials.

Overall Significance:

Rock Kleen presents a game-changing technology for the mining industry. It offers a solution to the environmental challenges of tailings piles while simultaneously recovering valuable resources.  This can contribute to a more sustainable and responsible mining future.
