The present invention relates generally to a process for removing dissolved or colloidal silica from a pregnant leach solution (“PLS”) More particularly, an exemplary embodiment of the present invention relates to a process which mixes PLS with an acid source, preferably lean electrolyte, to induce formation of colloidal silica that can then be collected and removed
usually consisting of silicates, and the pregnant leach solution (PLS) The solid-liquid separation of the post-leached slurry occurs in a series of counter current decantation thickeners (CCDs) After the acid insoluble residue has been separated from the leach solution it is washed and filtered prior to disposal in a residue storage facility

Heap leaching is an industrial mining process used to extract precious metals, copper, uranium, and other compounds from ore using a series of chemical reactions that absorb specific minerals and re-separate them after their division from other earth materials Similar to in situ mining, heap leach mining differs in that it places ore on a liner, then adds the chemicals via drip systems to the .
Aug 10, 2019· Pregnant laterite leaching liquors are always multicomponent mixtures of metal ions, usually with high contents of iron and aluminium and, besides nickel and cobalt, smaller amount of manganese, zinc and others (Mishra et al, 2016)Recovery of nickel and cobalt from these solutions usually involves solvent extraction to separate these two elements from the others present in the leaching solution
separation The concept of co-extraction (selective stripping) was used for many metal coupl It was also adopted in ammonia systems for Cu-Ni separation The paper presents the results of extraction of copper(II) from ammonia pregnant leach solutions (PLS), coming from leaching of copper sulfide concentrat Some
Oct 02, 2012· It beats my mind I would considered that the ore has no gold but we did fire assey test before starting the leaching process, we also took samples of the pregnant solution for test and it also came out very positive (mentioned the the values earlier) so am really worried but like u saying probably I missed something during the stripping the .
The bauxite residue sinks to the bottom of the settling tanks, then is transferred to the washing tanks, where it undergoes a series of washing stages to recover the caustic soda (which is reused in the digestion process) Further separation of the pregnant liquor from the bauxite residue is performed utilising a series of security filters
