Tank leaching is practised for the treatment of refractory gold ores. Bioleaching has also some potential for metal recovery and detoxification of industrial waste products, sewage sludge and soil

Bioleaching of an organic-rich polymetallic

The interest of using stirred tank reactor (STR) for the treatment of other minerals than refractory 51 gold ores, such as the base metal sulfides, has already been demonstrated but some

Reactor models for a series of continuous stirred tank

In this article in particular, model equations are developed for the case of a leaching reactor operating under pure gas-transfer control. That is, the transfer of a gaseous reactant at the g-1 interface is considered to be the controlling step of the process rather than the particle dissolution reaction itself.
