Abstract
Mining and metals processing are not invisible activities
and are heavy industries, which require energy, water,
chemicals, and land area. Recently more emphasis is given
to environmental and societal aspects in mining and
processing. Development of good practices with improved
resource efficiency, new recovery methods and
sustainability thinking are increasingly required. This
work shows pH titration method for acid mine drainage
(AMD) water incorporated with aqueous thermodynamic model
for selective metals precipitation from complex solution.
Also two examples on gold recovery methods from aqueous
streams are shown: biosorption using fungal matter and
solvent extraction using a task-specific ionic liquid. By
understanding chemical thermodynamics and natural
phenomena, there is a better chance of developing
solutions for environmental problems and new industrial
processes.
