This study examines the potential for use of biogenic sulphuric acid for leaching of a low-grade Brazilian ore containing 0.64% copper occurring as brochantite, Cu 4 SO 4 (OH) 6 , and as malachite, Cu 2 CO 3 (OH) 2 . Ore was agglomerated with element

Detrimental effects of corrosion in conjunction with bacterial activity in water pipeline systems have led to an increase in research in how to prevent such occurrences. In particular, sulphate-reducing bacteria (SRB), found in anaerobic conditions u

Solvent Extraction–Electrowinning (SX–EW) is a hydrometallurgical process involving the dissolution and reprecipitation of copper from solution. The organic phases which are widely used in the SX process are very important economically. On the ot

Molybdenum was bioleached from molybdenite-containing mine waste samples and from high purity molybdenite in solutions amended with ferrous sulfate. Bioleaching of Mo occurred when solution Eh exceeded 750 mV to 800 mV (s.h.e.). The rate of bioleachi

Source control of acid rock drainage (ARD) requires consideration of both biological and abiotic mechanisms of metal sulfide oxidation. A promising approach is to couple a biocide with phosphate for application to sulfidic waste materials. This appro

Refractory, sulfidic tailings from gold mining operations may be biooxidized to increase the amount of gold recoverable by cyanide extraction. Tailings containing thiocyanate must be pretreated to remove thiocyanate prior to biooxidation due to its t

The accumulation and possible metabolic transformation of tri-n-butyltin cation by tin-resistant estuarine bacteria was studied. The bacterial isolates accumulated tributyltin to 3.7–7.7 mg tin per g dry weight of cells by a nonenergy requiring pro

One hundred six strains of aerobic bacteria were isolated from the Fiora River which drains an area of cinnabar deposits in southern Tuscany, Italy. Thirty-seven of the strains grew on an agar medium containing 10μg/ml Hg (as HgCl2) with all of thes
