99.99% Dysprosium (" Dy ") has been produced from pregnant leach solution ("PLS") derived from the Company's Bokan -Dotson Ridge project in Alaska by the SuperLig ®-One Molecular Recognition Technology ("MRT") Pilot Plant at the IBC Advanced Technologies, Inc.

The PEA will examine surface mining in conjunction with tank leaching for the deposit, with on-site production of a lithium product from the leach solution.

Ucore has successfully utilized MRT to produce a near quantitative separation of a heavy rare earth concentrate ("HREE Concentrate") consisting of 99+% of rare earth elements from a pregnant leach solution ("PLS").

The preliminary leach results indicate relatively high grade pregnant leach solution (PLS) can be produced containing Li, K, Na and limited deleterious elements and a conventional downstream lithium recovery circuit should be applicable to produce saleable lithium carbonate or lithium hydroxide.

The current operation at Mineral Ridge is a heap-leach operation, which uses reactivated carbon to adsorb gold from the pregnant leach solution.

SuperLig ® Molecular Recognition Technology (" SuperLig ®") to bench scale separations of a number of valuable metals from a Pregnant Leach Solution ("PLS") derived from the tailings of the MOSP's process flow.

This effort resulted in the successful separation of REE based from Pregnant Leach Solution (PLS) from derived from Ucore's Bokan -Dotson Ridge project (see Ucore Press Releases dated June 7, July 5, Aug. 15 and Sept. 26 2016).

Pregnant leach solution ("PLS") is stored in a PLS pond then pumped to the ADR plant.

After saprolite neutralization, the nickel and cobalt will be recovered from the leach solution by conventional counter-current decantation (CCD), followed by limestone neutralization of excess acid and precipitation of iron, aluminium and other metals.

The leach pulp would be filtered in automatic pressure filters to separate pregnant leach solution from the leach residue.

Subsequently, the selective separation of precious materials contained in the leaching solutions was examined.

The treatment delaminates the EVA-layer which can then be skimmed from the leaching treatment solution.

The process works under pressure, and the degree of extraction rises as the pH value of the leaching solution falls.

A phase volumetric ratio of gallium-containing leaching solution to w/o emulsion of 20:1 was set.

Moreover the known procedure requires adding 1 g of lignine sulfate per liter of leaching solution.

It is known to use hydrogen peroxide when recovering precious metals by means of cyanide-containing leaching solutions.

The ore is roasted, leached with a solution of ammonia and carbon dioxide and then filtered.

We are familiar with state-of-the-art techniques for metal separation from leaching solutions through down-stream-processing towards the commercial end product.

The tighter structure results in a lower release of alkali metal on leaching by aqueous solutions.

For heap leaching facilities, where metals are extracted from ore heaps by percolating leach solutions, Member States shall undertake a screening for dangerous substances at closure based on an inventory of used leach chemicals and the residual concentrations of these leach chemicals in the drainage after washing has been finalised.

In all of the Examples the leaching solutions used contained 160 ppm of gallium (Ga) and 6 mol/l of HCl unless stated otherwise.

The leaching solutions of the Bayer process are ideal solutions for hydrometallurgical recovery of gallium in accordance witht he present invention.

After the removal of the leach residue from the solution obtained in the first hot leaching step, said solution is neutralized with lime to a pH value of about 4.5.

In accordance with a further preferred feature, the leach residue fed to step (a) is obtained by a hot acid leaching of the residue left after the neutral leaching of the roasted zinc concentrate, which hot acid leaching is effected at a temperature from 70° C. and the boiling point of the solution, a separation of the undissolved matter consisting of a lead-silver residue preferably with an addition of gelatin or polyalcohol, a reducing leaching of the solution with an addition of sphalerite, a separation of the undissolved matter, a recycling of said undissolved matter to the roasting step, a preneutralization of the solution by an addition of calcine or leached residue, a neutralization by an addition of calcine, a separation of the leached residue, a precipitation of the iron contained in the solution and a recycling of the solution to the neutral leaching step.

The ore-free leaching solution issuing from the bottom of the heap is circulated, part of the leaching solution being continuously removed from the circuit for the separation of noble metal and replaced by fresh leaching solution.

Recycling of the leaching solution is not possible in practice because disruption of the leaching process through accumulations of other metals could no longer be ruled out.

The O2 concentration should be from 2 to 20 mg O2 and preferably from 7 to 13 mg O2 per liter leaching solution.

Clearly, it is important that the H2 O2 concentration in the leaching solution is also kept low temporarily and locally.

A serious disadvantage of heap leaching is that the atmospheric oxygen required to oxidize the noble metal in the ore heap has to be introduced into the ore heap by the leaching solution.

Since the concentration of dissolved oxygen in the leaching solution decreases to a considerable extent from the top to the bottom of the ore heap, leaching is never complete, above all in the lower regions.

The phosphate-enriched biomass thus produced is removed from the leaching solution, for example by centrifuging or filtering.

In addition, the method of the invention may concurrently be used for efficient mobilization and recovery of heavy metals from the treated solid materials, for instance by concentrating heavy metals contained in the resulting leaching solution by membrane assemblies.
