Elixsys Inc. has developed an innovative modular chemical process to extract valuable minerals, metals, and rare earth elements from coal combustion waste with practically zero waste. The company plans to bring these materials to a variety of industrial supply chains and has already developed marketing agreements.
This process, known as Elixsys Module 2, leaches coal combustion products (CCPs) such as fly ash and is able to separate insoluble silica and solubilize most of the remaining elements. After solid/liquid separation, the liquor is sequentially precipitated to separate all the metals of interest. In addition, the final stream is also a product so Elixsys achieves a near-zero waste process. The metals can be separated as hydroxides, oxides and carbonates. The flowsheet selects the products to achieve the highest value products and the most economical reagents so that the overall process is highly profitable. These products include ferric oxide pigment, aluminum hydroxide, magnesium hydroxide, calcium carbonate, and a misch metal of rare earth elements and transition metals. The process was demonstrated repeatedly at the kg level in batch runs. Elixsys has partnered with Anactisis to take the misch concentrate, further concentrate that stream, and separate individual rare earth elements of high value to the US.
