摘要： A method for extracting secondary metal values from a sulfuric acid leachate is provided. The method includes providing a leachate which contains a primary metal and a plurality of secondary metals, wherein the primary metal is selected from the group consisting of Cu, Li and Ni and is derived from sulfuric acid leaching of an ore; passing the leachate through a first ion exchange resin which is selective to, and releasably binds, the plurality of secondary metals; stripping the plurality of secondary metals from the second or third ion exchange resins, thereby obtaining a first extract; and recovering the secondary metals from the first extract.

摘要： Calcium (Ca), manganese (Mn) and magnesium (Mg) carbonate plus lead (Pb) and zinc (Zn) sulphide minerals in a permeable host, crushed ore, concentrates or as mine discharge tailing are selectively solution mined (in-situ or ex-situ) with a selected acid e.g. acetic acid to extract Ca, Mn, and Mg followed by multivalent oxidizing salts e.g. ferric salts to extract Pb and Zn sequentially. For in-situ leaching, an inter relationship has been identified between pressure, temperature, target depth and leachate concentration such that carbonate leaching is performed in a manner to prevent carbon dioxide gas (CO2) discharge thereby plugging host rock permeability avenues to preclude further leaching. This requires controlling the rate of acetic acid leaching to be in step with availability of solution to dissolve the resulting discharged CO2. Sulphide leaching is subsequently conducted on the carbonate-depleted host. The two resulting leachates are chemically treated to selectively recover extracted minerals as value added industrially ready products. The in situ method is particularly advantageous in preparing the high purity manganese products necessary for lithium ion batteries because it prevents occurrence of very fine metallic particles in the products that may happen during conventional mining. Alternatively, the in situ carbonate recovery steps can be independently employed; all in an environmentally friendly manner.

摘要： The selective leaching of metal ions from various iron oxide and manganese oxide containing ores employs intermediary solutions. The leaching processes are based upon a redox acid leach step employing stabilized cuprous ions and, in one instance, a combination thereof with ferrous ions. Leaching is conducted at low temperatures, up to about 90.degree. C. and low pressures, up to about 1.5 MPa and at a pH of about 1.5 to 2.5. Nickel and cobalt recoveries from the ores, employing these processes, will usually equal or exceed 90 percent. The intermediary solutions comprise stabilized acidic cuprous ions Cu.sup.+ L wherein L is a stabilizing ligand selected from the group consisting of CO, XRCN and Cl.sup.-, X being --H or --OH and R being aliphatic having from one to about four carbon atoms. In at least one process, ferrous ions are introduced for a separate leaching step. Additional steps include regeneration of the lixiviant cuprous ion solutions and removing a portion of the copper ions from the copper ion solution before or after the step of regenerating. Several processes for the regeneration are possible employing quinolic compounds, H.sub.2, CO or syngas as reductants.

摘要： Metal values are extracted from manganiferous ocean floor nodule ore by treating the ore with hydrochloric acid, thereby producing chlorine and a starting pulp containing a solution of the metal chlorides and a solid residue. The starting pulp is subjected to at least two subsequent acidifications with HCl, each acidification being followed by addition of fresh ore, thereby producing chlorine and a final pulp containing a concentrated solution of metal chlorides and a solid residue. The solid residue is separated from the concentrated solution and substantially all the metal values, except manganese and alkali and alkaline earth metals, are separated from the solution. The manganese is separated from the solution by treatment with chlorine, at least the major portion of which was produced in the preceding leaching steps, while maintaining the solution at a pH of between about 3 and 7 by addition of a neutralizing agent such as MgO or Mg(OH).sub.2 whereby the manganese is precipitated in the form of MnO.sub.(1.sub.+x) in which x is between 0.5 and 0.7. The manganiferous precipitate is separated from the resulting solution of magnesium chloride and the latter is pyrohydrolysed in the atomized state to regenerate the neutralizing agent and HCl, which can be recycled.
