The anthropogenic activities in agriculture, industrialization, mining, and metallurgy
combined with the natural weathering of rocks, have led to severe contamination of soils by …

There has been a strong interest in technologies suited for mining and processing of low-
grade ores because of the rapid depletion of mineral resources in the world. In most cases …

Although jarosite and visible light are important factors for the formation of acid mine
drainage (AMD), the effects of combined jarosite and visible light on chalcopyrite …

The study investigated the leaching efficiency and microbial flora of an electro-assisted
biochemical cycle reactor were investigated for gold ore bio-oxidation. The results showed …

Redox potential (ORP) was proved to be a key factor in promoting chalcopyrite (CuFeS 2)
bioleaching. Though there are some methods for maintaining ORP reported previously, little …

Pyrite-mediated arsenopyrite oxidation is an important process affecting arsenic (As)
mobility. The iron sulfides-induced reactive oxidation species (ROS) can exert significant …

The oxidative dissolution of As from arsenopyrite, one important arsenic mineral in reducing
conditions, poses an environmental hazard to natural aquatic systems. The dissolution of …

The bioleaching process is widely used in the treatment of ores or solid wastes, but little is
known about its application in the treatment of vanadium-bearing smelting ash. This study …

The huge amount of pyrite wastes not only occupy a lot of lands, but its oxidation also
releases considerable amounts of ferric iron and acid into the environment to form acid mine …

This study investigated the effect of designed microbial consortia on biomining of low grade
base-metal sulfide tailings. The results show the amount of recycled metals were equal if the …
