Abstract: The present invention embodies a process for extraction of nickel, cobalt, and other metals from laterite ores by heap leaching, and of the product obtained as well, characterized by the fact that it is comprised of crushing (I), agglomeration (II), stacking (III), and heap leaching (IV) stages, with this last stage being a continuous, counter-current, heap leaching system with two or more stages, comprised of two phases, one of which is composed of the ore (solute), and the other is composed of the leaching solution, or solvent, which are supplied at opposite ends of a series of stages and flow in opposite directions. Upon cessation of leaching in the last stage, its solute is removed and a new stage is introduced at the first position, formed by new ore (solute) to be leached by the solvent solution, which is introduced from the last stage, percolating or flowing though all the previous stages until it reaches the first stage, being separated if loaded with target metals (PLS).

Abstract: A method for recovering base metal values from oxide ore is provided, where the ore includes a first group metal selected from iron, magnesium and aluminum and a second group metal selected from nickel, cobalt and copper. The method includes reducing ore particle size to suit the latter unit operations, favoring contact of the metal elements, contacting the ore with ferric or ferrous chloride, hydrated or anhydrous, to produce a mix of ore and iron(II or III) chloride, subjecting the mixture of the ore and ferric or ferrous chloride to enough energy to decompose the chlorides into hydrochloric acid and a iron oxide, contacting the readily-formed hydrochloric acid with the base metal oxides from the second group, forming their respective chlorides, selectively dissolve the produced base metal chlorides, leaving the metals as oxides and in the solid state, and recovering the dissolved base metal values from aqueous solution.

Abstract: The present invention resides in a process of recovering nickel and cobalt, regenerating the main raw materials, said process including the steps of: granulometric separation; leaching; neutralization; MHP production in only one stage and the pressure crystallization of magnesium sulphite. The process proposes a way to recovery nickel and cobalt from laterite ores through the atmospheric and heap leaching with staged addition of ore—by size separation—and H2SO4, decreasing the nickel losses and simplifying the neutralization circuit and producing a more purified MHP. The present process route is employed for nickel extraction, including the one from high magnesium containing lateritic ores.

Abstract: A hydrometallurgical resin-in-leach (RIL) process for directly recovering nickel and/or cobalt. Simultaneous pulp leaching by adding an acid or base, dissolves the metals of interest with adsorption of the metals rendered soluble in on ionic exchange resin. Following elution of the changed resin, purification of nickel and cobalt present in the eluate can be recovered by conventional methods, such as precipitation, extraction by solvents and membranes. The regenerated resin is recirculated for further use.

Abstract: A method and system of removing or decreasing waste liquor manganese concentration to less than about 1 mg/L total manganese without the precipitation of significant amounts of magnesium. The method and system include steps for treating the waste liquor using three separate circuits in which in the first circuit, manganese is reduced, for example, from about 2 g/L to <500 mg/L using pH adjustment with a suitable neutralizing agent; and in the second circuit, the final target manganese level is achieved by oxidative precipitation using a suitable oxidizing agent. Part of the precipitated manganese product, e.g., MnO2, is recycled to the oxidative precipitation circuit as seed and the balance proceeds to a third circuit wherein the precipitated manganese product is re-dissolved, and then recycled to the first neutralization circuit. In the first neutralization circuit and the second oxidative precipitation circuit, the process conditions are selected to minimize the precipitation of magnesium, e.g., Mg(OH)2.

Abstract: A method for improving the environmental stability of cathode materials used in lithium-based batteries. Most currently used cathode active materials are acutely sensitive to environmental conditions, e.g. leading to moisture and CO2 pickup, that cause problems for material handling especially during electrode preparation and to gassing during charge and discharge cycles. Binder materials used for making cathodes, such as PVDF and PTFE, are mixed with and/or coated on the cathode materials to improve the environmental sensitivity of the cathode materials.
