Mineral processing system performs product movement and processing within a secured room using robotics and computerized automation. A heated chemical processing well provides a hot bath wherein raw mineral is submersed into a separating agent. Used separating agent and residual mineral waste can be automatically disposed of at a chemical dumping station. New separating agent can be automatically loaded into hot baths. Crucibles contain separating agent during mineral processing, and can be used to transport waste from the processing station to the dumping station. A mineral basket can transport and contain mineral during processing. Crucibles and baskets can be made of Inconel, stainless steel, or other material suitable for high temperature processing. A lid/cover includes transducers (e.g., thermal, liquid level) for monitoring processing operations within the well. A separating material delivery port and a vent integrated with the lid/cover that can be used to collect and contain harmful vapors.
