Abstract

Language:

Precipitation of gypsum and the formation of scale pose significant challenges in the leaching of various minerals, particularly impacting maintenance needs and recovery rates for precious elements like gold. This study investigates the effects of different biopolymers on the rheological properties of gypsum across varying pH levels and temperatures. Key findings indicate that the dispersal of gypsum is influenced by pH, temperature, and the specific biopolymer employed, with an inverse relationship observed between dispersibility and scaling potential. Additionally, zeta potential measurements show that increasing biopolymer concentration alters both the magnitude of the zeta potential and the dispersion quality of gypsum suspensions. The implications of these results extend to the selection of additives in mineral processing applications where scaling issues arise, offering valuable insights for mitigating scale-related challenges.
