LST Heavy Liquid for density separations
Recycling LST Heavy Liquid
LST Heavy Liquid can be recovered from minerals quite easily by firstly washing the separated minerals with deionised water, filtering, and then concentrating the water washings by evaporation through boiling. The LST Heavy Liquid is not volatile so it is concentrated as the water evaporates. In this way, LST Heavy Liquid can be recycled with greater than 99% efficiency. The overall scheme for use in an industrial laboratory is shown below:
The recovery of LST Heavy Liquid is high by this method. Typically, only 1.5 mL per kilogram of mineral sample of LST Heavy Liquid is lost with general usage.
