Abstract: THIS invention relates to a method and heap for recovering metal values from ore in a heap leach process. The method includes the steps of depositing and stacking crushed ore 16 on an impermeable pad 12 to form a heap, and enclosing the heap with a substantially impermeable coating 18 to both gas and liquid; to form a sealed heap. The sealed heap is irrigated with a leachant added inside the top of the heap, allowing the leachant to percolate through the heap and removing leachant at the base of the heap, either for recirculation or subsequent processing. Oxygen containing gas is added to the base of the sealed heap.

Abstract: A process is disclosed for the recovery of valuable metals from oxidic ores, in particular from polymetallic nodules. The process is suitable for the recovery of Cu, Co, Ni, Fe, and Mn, which are the main metals of interest in such polymetallic nodules. The present process is, among others, characterized by the handling of Fe, which is dissolved and kept in solution until the step of crystallization rather than removed at an earlier stage. A mixed Mn—Fe residue is obtained, which, after thermal treatment, provides a Mn—Fe oxide that is suitable for the steel or for the manganese industry. Excellent Cu, Co and Ni yields are obtained, while Fe is leached and valorized together with Mn.

Abstract: A method for producing briquettes made of a waste material includes provisioning of at least one metal and at least one organic material. The waste material is mechanically prepared in a single or multiple stages and at least one first fraction of the waste material is separated. A briquette mixture containing the at least one first fraction is produced, wherein the at least one first fraction has a calorific value of 0 MJ/kg to 30 MJ/kg. A calorific value of the briquette mixture is adjusted by varying at least the first fraction. The briquette mixture is introduced into a briquetting device and pressed into briquettes. Briquettes with a calorific value of 5 MJ/kg to 30 MJ/kg and with a maximum copper content of 0.1 wt % to 20 wt % are produced.

Abstract: Disclosed is a method for recovering a waste lithium cobalt oxide battery, the method comprising: feeding a lithium cobalt oxide battery black powder in a column-shaped container, adding a first acid to the column-shaped container for heat leaching until solids in the column-shaped container are not reduced any more so as to obtain a first leachate and leaching residues, wherein the first acid is a weak acid, and a filtering structure is arranged at the bottom of the column-shaped container; and adding a second acid to the column-shaped container containing the leaching residues for heat leaching until solids in the column-shaped container are not reduced any more so as to obtain a second leachate and graphite, wherein the second acid is a strong acid.

Abstract: A method can prepare an aqueous mineral suspension from an aqueous metal ore residue into which there is introduced a polymer (P) having a molecular weight Mw measured by GPC of from 100,000 to 3.106 g/mol and prepared by free radical polymerization of at least one anionic monomer (m). The suspension produced may have a Brookfield viscosity greater than 2,000 mPa·s and/or a flow threshold of greater than 40 Pa.

Abstract: An oxidation step for sulfide and transition ores prior to CN leaching to recover 60 to 90 percent of metals from those ores. Use of tona, soda ash or carbonate source in treating sulfide and transition ores for CN leaching recovery of metals, including gold and silver. The oxidation of sulfide and transition ores in the presence of carbonate. Low moisture content in the heap, to enhance available oxygen, during the oxidation of sulfide and transition ores in the presence of carbonate.

Abstract: The present disclosure concerns a process for the recovery of valuable metals from polymetallic nodules. A two-stage process using SO2 in an acidic aqueous media is disclosed. In a first step, performed in mildly acidic conditions, Mn, Ni, and Co are dissolved; in a second, more acidic step, Cu is dissolved. Under these conditions, the leachate of the first step contains most of the Mn, Ni, and Co, while being nearly Cu-free. The Ni and Co are precipitated as sulfides; the Mn can be recovered as sulfate by crystallization. Cu, which is leached in the second step, is selectively precipitated, also as sulfide.

Abstract: The system may include a secondary irrigation feature that determines a percent of overlap of each of a plurality of submodules in a first lift over each of a plurality of submodules in a second lift and adjusts at least one of leaching operations or a leaching model based on the total tonnage weighted average of metal in the second lift. The method may further comprise determining an acid gap based on a difference between total acid given and total acid consumption; and further adjusting at least one of the leaching operations or the leaching model based on the acid gap. The method may further comprise determining a percentage of compacted material based on the material that is compacted and irrigated divided by the material that is irrigated; and further adjusting at least one of the leaching operations or the leaching model based on the percentage of compacted material.
