摘要： ABSTRACT A process is described for leaching a value metal from an ore containing said value metal, the process including the steps of leaching the ore in the presence of hydrochloric acid so as to form a soluble metal-chloride salt in a leach solution; adding sulphuric acid and/or sulphur dioxide to the leach solution; recovering a solid metal-sulphate or metal-sulphite salt from the leach solution; regenerating hydrochloric acid; and continuously transferring at least a portion of the regenerated hydrochloric acid in solution to the vapour phase. The vapourised hydrochloric acid is then captured and returned to the leaching step. The sulphuric acid and/or sulphur dioxide may be added to the leach solution during or after the leaching step. The value metal is typically selected from the group consisting of Zn, Cu, Ti, Al, Cr, Ni, Co, Mn, Fe, Pb, Na, K, Ca, platinum group metals and gold. The metal in the metal-sulphate or sulphite salt may be the value metal, or may be a metal of less value than the value metal, such as magnesium.

摘要： A process is described for leaching a value metal from an ore containing said value metal, the process including the steps of leaching the ore in the presence of hydrochloric acid so as to form a soluble metal-chloride salt in a leach solution; adding sulphur dioxide to the leach solution; recovering a metal-sulphate or metal-sulphite salt from the leach solution; and regenerating hydrochloric acid. The ore may be an oxidic base metal ore, such as a zinc oxide ore; a lateritic nickel ore, such as a saprolitic or limonitic ore; a sulphide ore or a titanium ore. The value metal is typically selected from the group consisting of Zn, Cu, Ti, Al, Cr, Ni, Co, Mn, Fe, Pb, Na, K, Ca, platinum group metals and gold. The metal in the metal-sulphate or sulphite salt may be the value metal, or may be a metal of less value than the value metal, such as magnesium. The regenerated hydrochloric acid is recycled within the leach process.

摘要： A process is described for leaching a value metal from an iron-containing ore, the process including the steps of leaching the ore in an acidic sulfate solution so as to form an iron-sulfate salt in a leach solution; adding sulfur dioxide to the leach solution during and/or after the leaching to regenerate acid; and recovering the iron-sulfate salt from the leach solution. The value metal is typically Zn, Cu, Ti, Al, Cr, Ni, Co, Mn, Fe, Pb, Na, K, Ca, Ag, Au or a platinum group metal. The leaching solution can also include chlorides. One or more value metals, such as nickel and/or cobalt, may be recovered with the iron sulfate salts and can subsequently be separated from the iron sulfate salts. The recovered iron sulfate salts can be decomposed to iron oxides without decomposing the sulfate salts of the other metals or whilst also decomposing the sulfate salts of the other metals, those other metals being recovered by posttreatment of the iron oxide calcine. The regenerated acid is typically recycled within the leach process.

摘要： A method for producing a metal from a metal sulphide ore or mineral is claimed. The metal sulphide ore is leached by non-oxidative dissolution in a chloride solution to produce a metal chloride solution and hydrogen sulphide; the metal chloride solution is subjected to one or more electrolytic processes to produce chlorine gas; and the chlorine gas is then converted into hydrochloric acid. The chlorine may be produced in an electrolytic cell, such as a zinc metal electrowinning cell, a chlor-alkali cell, an iron metal electrowinning cell, a manganese metal electrowinning cell, an iron- manganese alloy electrowinning cell or any combination of these cells or any other electrolytic cell that can selectively remove a metal from solution while producing chlorine at the anode. The metal may be Zn, Cu, Mo, Ti, Al, Cr, Ni, Co, Mn, Fe, Pb, Na, K, Ca, Ag, Au or any platinum group metal.
