  • New approaches for extracting and recovering metals from

    However in the chemical extraction of the processes tailings more copper was extracted from those tailings bioleached at 30 °C. Therefore it can be assumed that less copper was extracted from the tailings leached at 30 °C than at 45 °C but somehow copper was precipitated in a nonsoluble for that is not susceptible to chemical extraction by the method used.

  • Cobalt and nickel recoveries from laterite tailings by

    Those tailings are residues from the CARON process which is the main technology most laterite processors used to extract nickel and cobalt. In this process after roasting at up to 800 °C an ammonium carbonate solution dissolves the metals and separates them from the ore.

  • NICKEL AND COBALT ORES: FLOTATION

    The usual method of nickel extraction from sulRde ores is through the production of nickel matte after enriching the nickel content of the ore. This is com monly carried out by magnetic separation Sotation or a combinationof both after the ore is comminuted to below 200 m in size.

    During extraction of the oil from oil sand tailings consisting of water silt clays and other solvents are also created. This solid will become mature fine tailings by gravity. Foght et al (1985) estimated that there are 10 3 anaerobic heterotrophs and 10 4 sulfatereducing prokaryotes per milliliter in the tailings pond based on conventional most probable number methods.

  • Recovery of Nickel and Cobalt from Laterite Tailings by

    We show here that the ferric iron reduction mediated by Acidithiobacillus thiooxidans can be applied to an aerobic reductive dissolution (AeRD) of nickel laterite tailings. AeRD using a consortium of Acidithiobacillus thiooxidans and Acidithiobacillus ferrooxidans extracted similar amounts of nickel (53 57%) and cobalt (55 60%) in only 7 days as AnRD using Acidithiobacillus ferrooxidans.

    Mine Tailings. Many tailings are toxic and must be kept perpetualy isolated from the environment. Scale of tailings production is immense since metal extraction is usually only ounces or pounds for every ton of ore. Tailings containment facilities are regarded as the world's largest manmade objects.
