Abstract: A process of leaching a metal or salt thereof from a feed source includes combining an indifferent salt to a leach system to increase efficiency of the leach process as well as the subsequent leach residue liquid-solids separation. The process can include combining the feed source with a leaching reagent and an indifferent salt in a leach medium to form a feed slurry and leaching a metal or metal salt from the feed slurry in to a pregnant leach liquor followed by recovering metal salts from the pregnant leach liquor and recycling residual leach solution to form additional feed slurry. Such processes are suitable for large scale operations with high solids loading in the liquid-solids separation operations.

Abstract: The present disclosure relates to methods by which lead from spent lead-acid batteries may be extracted, purified, and used in the construction of new lead-acid batteries. A method includes: (A) forming a mixture including a carboxylate source and a lead-bearing material; (B) generating a first lead salt precipitate in the mixture as the carboxylate source reacts with the lead-bearing material; (C) increasing the pH of the mixture to dissolve the first lead salt precipitate; (D) isolating a liquid component of the mixture from one or more insoluble components of the mixture; (E) decreasing the pH of the liquid component of the mixture to generate a second lead salt precipitate; and (F) isolating the second lead salt precipitate from the liquid component of the mixture. Thereafter, the isolated lead salt precipitate may be converted to leady oxide for use in the manufacture of new lead-acid batteries.

Abstract: 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.

Abstract: In embodiments, pressurized fluid containing reagents of formulated mixtures of solids, liquids and gasses are delivered into a cased well then into the heap or pile to open or stimulate new horizontal and vertical fluid pathways, channels, plus drains from the open bottom of the well to the bottom of the heap or pile for fluid collection. This delivery method may also drain any fluids that are retained and pooled in the heap or pile. The removal of pooled fluids will increase the inter-particle cohesion and friction in the heap or pile, thus adding geotechnical stability and resistance to movement of the heap or pile. The cased wells may also add shear strength to the collective to retard movement of the heap or pile.

Abstract: A method for producing a solid scandium-containing material comprises providing an aqueous solution containing carbonate ions, carbamate ions, hydrogen carbonate (HCO3+) ions, or mixtures thereof, contacting the aqueous solution with a scandium containing material containing one or more impurities to produce a scandium-loaded solution and a depleted scandium containing material, separating the depleted scandium containing material from the scandium loaded solution, treating the scandium loaded solution to cause precipitation of a solid scandium-containing material while avoiding or minimizing precipitation of impurities present in the aqueous solution, and separating the solid scandium-containing material from the solution. In another embodiment, a high purity scandium containing is produced by contacting a solid material containing scandium with an acid to form a scandium loaded solution, separating the scandium loaded solution from any solids, adding additional acid to the scandium loaded solution to reduce the pH and precipitating a high purity scandium oxalate material by adding oxalic acid to the solution.
