Web1 jul. 1997 · Bioleaching is a simple and effective technology for metal extraction from low-grade ores and mineral concentrates. Metal recovery from sulfide minerals is based on the activity of chemolithotrophic bacteria, mainly Thiobacillus ferrooxidans and T. thiooxidans, which convert insoluble metal sulfides into soluble metal sulfates. Non-sulfide ores ... Web6 apr. 2024 · Applications of machine learning techniques applied to mineral leaching modeling can be found in Golmohammadi et al. (2013), where a quantitative study based on partial least squares (PLS) and artificial neural network (ANN) is developed for the prediction of ferric iron precipitation in the bioleaching process, and in Xie et al. (2016), an ...
