  A Fuzzy Control Method Based on Rule Extraction for …

  2023810 · Abstract In the neutral leaching process of zinc hydrometallurgy, the pH value directly afects the leaching rate of zinc calcine. How-ever, due to the complex mechanism of the leaching process and the frequent fluctuation of working conditions, it is dificult to control the pH value by manual control. Therefore, this paper proposes a fuzzy …
