Copper Directly Extracted From Difficult Sources Using Lixivia’s SELEX-CuTM Chemistry and Process

Santa Barbara, CA: Lixivia demonstrates direct copper extraction in water using safe and eco-friendly chemicals. This achievement will help reduce emissions, reduce mining burdens and utilize already large stockpiles of copper tailings. We believe this technology is applicable to a variety of ores types, tailings and other recycled materials.

Copper mining is resource and land intensive. Copper ore quality continues to decline leading to even larger amounts of mining volumes. These activities conspire to produce billions of tons of tailings each year. Lixivia’s SELEX-CuTM enables copper to be safely extracted from tailings, ores and other sources.

  • High quality copper extraction

  • Eco-friendly process and chemicals

  • Water-based

  • Extending and expanding existing resources

About Us: Lixivia is a venture-backed start-up located in Santa Barbara, California. Our mission is to be the leading supplier of breakthrough chemistry and processes to the mineral industry, that enable reduced emissions while increasing revenues and profits.

Selective Cobalt Extraction, From Ore to Batteries

Lixivia uses its SELEX-Co to selectively remove cobalt from a variety of sources

Santa Barbara, CA: Lixivia develops new extractive technology to selectively remove cobalt from a variety of complex sources. Cobalt is a critical element in a large number of high tech industries, everything from smartphones to electric vehicles, to super magnets and special alloys. It is rare and where it is found is often riddled with turmoil, a great article about cobalt can be found here. Furthermore, on a global scale, very little is recycled.

Using our SELEX process, we are able to selectively remove cobalt from old smartphone batteries, using nothing more than a beaker, some water and our extraction agents. Highlights:

  • Selective cobalt extraction from batteries, tungsten alloys and other sources demonstrated

  • Environmentally friendly process and chemicals

  • Simple to implement

  • Expands cobalt supply away from conflict regions

Lixivia Obtains Ultra-Pure Calcium Carbonate from Highly Expansive Steel Slag

Precipitated Calcium Carbonate using the SELEXTM process has less than 1 ppb lead

Working with leading players in the steel industry, Lixivia has used its proprietary chemistries and processes to selectively extract and produce ultra-pure calcium carbonate (PCC) from steel slag. The Company has recently demonstrated that pure, high value minerals can be regenerated from fresh and legacy steel slag.  If one large steel company were to introduce this technology throughout their operations, then 2 million tons of PCC could eventually be brought on to the market. Furthermore, steel companies are uniquely positioned, geographically, to exploit major markets around the world.

Lixivia’s process solves two fundamental problems that inhibit steel slag from being re-purposed; stabilizing the slag to allow use in civil engineering applications and producing the highest purity calcium minerals that are commercially available. This breakthrough will reduce landfilling of steel slag, sequester CO2, reduce mining activities and provide a new supply route to calcium minerals such as precipitated calcium carbonate at an exceptional quality and price.  

Mineral producers will be able to decouple the geology traditionally associated with synthetic calcium minerals from their regional markets they serve best. Traditionally, companies require a high-quality limestone mine that may be distant from their markets, consume huge amounts of energy to dig up and process the mineral, and then even more energy to transport it to the end-user. This process releases millions of tons of CO2.

Lixivia’s SELEX process technology enables mineral and slag processing companies to:

  • Produce ultra-pure calcium minerals from steel slag with less than 1 ppb of lead and market leading cost

  • Engineer properties and performance of the calcium minerals

  • Reduce landfills

  • Sequester millions of tons of CO2 to benefit the environment

  • Minimize energy consuming processing and transportation of minerals

Glencore Predicts Large Need For Cobalt

Lixivia and Harsco, Inc. To Jointly Present At The 13th Global Slag Conference, April 24-25

Presentation Title: ‘Pilot-scale extraction of valuable high-purity calcium salts from steel slag,’ Mark Tilley, Lixivia Inc.; Nick Jones, Harsco

Here is a link to the program:

The presentation will focus on the pilot plant work that generated high quality precipitated calcium carbonate using steel slag supplied by Harsco. Steel slag is a major issue globally. Steel has limited uses, primarily because of its expansive nature. The slag contains large amounts of reactive calcium that upon exposure to air and water carbonate. This carbonation leads to cracking and expansion of slag, thereby limiting its use in a variety of construction and civil applications. Lixivia has shown that we can remove this expansion while generating high quality products from the slag itself. This technology could revolutionize the steel slag and precipitated calcium carbonate markets.

Lixivia presents at the Cobalt Institute Annual Conference in Las Vegas, NV

Presentation Title: Selective Aqueous Extraction of Co from Waste Sources

Our presentation focused on the use of technology on the extraction of cobalt from lithium ion battery waste. The largest challenge in the industry is the concentration of cobalt reserves, most are located in the Congo. This presents large geopolitical risk. The other main risk to cobalt supply is that the vast majority of the cobalt is produced as a secondary product to copper and nickel. We think that recycling technologies offer a way to alleviate these risks and potentially supply large amounts of cobalt to the market. The IEA predicts 11 million tons of battery waste produced by electric vehicles by 2030. It's our goal to be a provider of process and chemistry to ethically and ecologically extract and produce cobalt and other important metals from this waste source.
