Overview

Examines isotope variations in brine, suggesting insights into potassium mineral extraction efficiency.

Key Points

  • The goal is to explore the dynamic changes in hydrogen and oxygen isotopes in subsurface brine during the dissolution of potassium minerals.
  • Analyzed brine samples from water-supplement channels and observational wells at different depths.
  • Conducted hydrochemical and hydrogen-oxygen isotope analysis.
  • Studied the hydrological interactions during solid-liquid transitions in the brine.
  • Brine ion concentrations are influenced primarily by the dissolution and precipitation of halite, carnallite, and kieserite.
  • Hydrogen and oxygen isotope enrichment in brine is caused by evaporation and mineral dissolution after lake water supplementation.
  • The combined effects of brine mixing and mineral leaching are key factors affecting isotope changes.
  • Isotope ratio variations can indicate the potassium extraction efficiency during liquid extraction processes.
