Heap leaching is a widely used process in the mining industry for extracting valuable metals from ores, particularly copper and gold. This method involves stacking crushed ore in heaps and ...

Moreover, the use of hydrogen peroxide in the leaching process has emerged as a novel technique to minimize ammonia wastewater production, a common issue in traditional tungsten metallurgy.

Aparicio-Aragón, W.B., Ttito-León, S. and Valencia-Pacho, M.Y. (2025) Determination of Heavy Metal Adsorption Capacity of ...

Bioleaching of Metals. A number of metals are currently recovered by hydrometallurgy (dissolution in aqueous solution, leaching from ore, and reprecipitation), frequently using microorganisms that ...

This feeds into a hydrometallurgical treatment, that includes the dissolution of the base metals oxidised in the thermal process with dilute acid followed by hypochlorite brine gold leaching by ...
