In a method for recovering a copper sulfide concentrate by froth flotation from an ore containing an iron sulfide, wet grinding of the ore with grinding media made of high chromium cast iron alloy having a chromium content of from 10 to 35% by weight is combined with an addition of hydrogen peroxide to the conditioned mineral pulp before or during flotation in order to improve concentrate grade and recovery of copper sulfides.

A method for recovering one or more of copper, uranium and a precious metal from an ore material, including: (a) forming a heap of the ore material; (b) during active heap irrigation, contacting the heap of the ore material with an iron containing acidic leach liquor having a high chloride content in the presence of an oxygen containing gas, and producing a pregnant leach solution; and (c) recovering one or more of copper, uranium and a precious metal from the pregnant leach solution.

The method may comprise receiving historical data (e.g., mineralogy data, irrigation data, raffinate data, heat data, lift height data, geographic data on ore placement and/or blower data); training a predictive model using the historical data to create a trained predictive model; adding future assumption data to the trained predictive model; running the forecast engine for a plurality of parameters to obtain forecast data for a mining production target; comparing the forecast data for the mining production target to the actual data for the mining production target; determining deviations between the forecast data and the actual data, based on the comparing; and changing each of the plurality of parameters from the forecast data to the actual data to determine a contribution to the deviations for each of the plurality of parameters.

An operation method of a copper-smelting furnace is characterized by including supplying an Fe metal source into a copper-smelting furnace together with a feeding material including copper concentrate and a flux, the copper concentrate including Al, the Fe metal source including an Fe metal of 40 mass % to 100 mass %.

A method for extracting copper values from a low grade copper ore feedstock is provided. The method includes (a) providing an ore feedstock of a copper oxide ore; (b) subjecting the ore to at least one process selected from the group consisting of primary crushing processes and secondary crushing processes; (c) subjecting the ore feedstock to high pressure grinding roll crushing, thereby obtaining a crushed ore; (d) subjecting the crushed ore to acid curing, thereby obtaining a cured ore; (e) subjecting the cured ore to vat or heap leaching, thus yielding a leachate; (f) passing the leachate through a first ion exchange resin which is selective to base metals plus copper, thereby removing a portion of the copper values from the leachate and yielding a first loaded resin and a first treated leachate; (g) stripping base metals plus copper values from the first loaded resin with a first stripping solution, thereby yielding a base metals plus copper-loaded stripping solution; (h) selectively extracting copper values from the copper-loaded stripping solution via solvent extraction, thereby obtaining an extract and a raffinate; and (i) crystallizing a copper salt from the extract, thereby obtaining a crystallized copper salt.

Apparatus for use in, or forming part of, a separation process to be implemented in separation processor technology, the apparatus comprising synthetic bubbles or beads configured with a polymer or polymer-based material functionalized to attach to a valuable material in a mixture so as to form an enriched synthetic bubbles or beads having the valuable material attached thereto, and also configured to be separated from the mixture based at least partly on a difference in a physical property between the enriched synthetic bubbles or beads having the valuable material attached thereto and the mixture.

A TSL lance has an outer shell of three substantially concentric lance pipes, at least one further lance pipe concentrically within the shell, and an annular end wall at an outlet end of the lance which joins ends of outermost and innermost lance pipes of the shell at an outlet end of the lance and is spaced from an outlet end of the intermediate lance pipe of the shell. Coolant fluid is able to be circulated through the shell, by flow to and away from the outlet end. The spacing between the end wall and the outlet end of the intermediate pipe provides a constriction to the flow of coolant fluid to increase coolant fluid flow velocity therebetween. The further lance pipe defines a central bore and is spaced from the innermost lance pipe of the shell to define an annular passage, whereby materials passing along the bore and the passage mix adjacent to the outlet end of the lance. The end wall and an adjacent minor part of the length of the shell comprise a replaceable lance tip assembly.

A process for removal of aluminium and iron in the recycling of rechargeable batteries comprising providing a leachate from black mass, adding phosphoric acid (H.sub.3PO.sub.4) to said leachate and adjusting the pH to form iron phosphate (FePO.sub.4) and aluminium phosphate (AlPO.sub.4), precipitating and removing the formed FePO.sub.4 and AlPO.sub.4, and forming a filtrate for further recovery of cathode metals, mainly NMC-metals and lithium.

Provided is a method for producing metal microparticles in which the ratio of crystallite diameter to the particle diameter of the metal microparticles is controlled. At least two types of fluid to be processed are used, including a metal fluid in which a metal or a metal compound is dissolved in a solvent, and a reducing agent fluid which includes a reducing agent. Sulfate ions are included in one or both of the metal fluid and the reducing agent fluid. The fluid to be processed is mixed in a thin film fluid formed between at least two processing surfaces, at least one of which rotates relative to the other, and which are disposed facing each other and capable of approaching and separating from each other, and metal microparticles are precipitated. The present invention is characterized in that at this time, the ratio (d/D) of the crystallite diameter (d) of the metal microparticles to the particle diameter (D) of the metal microparticles is controlled by controlling the molar ratio of metal and sulfate ions in the mixed fluid to be processed.
