Optima supports Black Mass recycling and battery recovery development

By | Featured

Recycling lithium-ion batteries has several benefits, including reducing the demand for new raw materials, lowering the environmental impact of mining, and reducing the amount of hazardous waste that would otherwise end up in landfills.

Chemical separation, Black Mass recovery, is one of the techniques used in the recycling of batteries to recover valuable metals like lithium, cobalt, nickel, and copper. The process involves the use of chemicals to selectively dissolve and extract metals from the battery materials.

One common chemical separation process used in battery recycling is hydrometallurgy, which involves the use of aqueous solutions to dissolve and extract metals from battery materials. The process typically involves several steps, including:

  1. Leaching: The shredded materials are then treated with an acidic or alkaline solution to dissolve
    the metals.
  2. Purification: The dissolved metals are purified to remove impurities and other metals that are
  3. Recovery: The purified metals are then recovered from the solution by precipitation or electro-

The recovered metals can then be further refined and processed into high-purity materials that can be used in the production of new batteries or other products. The choice of technique depends on the type of battery and the specific metals that need to be recovered.

Optima has assisted several companies in developing specialty cathode materials and battery additive materials and are now working with companies on how to solve the recycling of the metals back into the battery. We have successfully developed the pilot processes and commercial process for these chemistries. Maybe we can assist you in solving problems and developing your commercial process.

Optima invests into improving process safety management

By | News & Info

Belle, WV – Optima Chemical Group LLC is proud to implement a new tool towards improving safety for potentially hazardous processes. An Advanced Reactive System Screen Tool (ARSST) was recently purchased and installed in Belle, WV to aide in the understanding of process safety critical parameters. The information produced from this specialized calorimeter will be used during process planning and development for prevention of related undesirable conditions.

Safety is essential to any process operation and obtaining information is key to that. Compliance requirements and good business practices tend to have a common theme related to the adequate process safety information; It is imperative that companies have the proper level information to ensure processes can be conducted safely under both desired and worst-case scenarios. 

It is critical to understand how robust the desired reaction is to ensure that process changes do not result in catastrophic events. The ARSST is developed by Fauske and associates to serve as a rapid screening adiabatic tool that can simulate upset scenarios and be used to prevent or manage the effects of a chemical related accident. Bench scale simulations yield directly scalable data that can be used to quantitatively highlight the consequences of runaway reactions, non-condensable gas formation, cooling variations, mischarged materials, and other upset conditions. 

From a business perspective an added benefit is that it contributes directly to risk mitigation and disruption prevention. From a risk management and process safety perspective, this new investment is a natural evolutionary next step at Optima Chemicals and we are happy to include it into our future preliminary hazard assessments. We are also re-evaluating existing processes to better understand what potential hazards we have in our existing processes.
