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.

The invention relates to a control system for a copper extraction process having at least a leaching phase, a solvent extraction phase and an electrowinning phase, the leaching phase comprising a post leach thickener. The control system comprises first measuring units to measure volume and total suspended solids in an influent of the post leach thickener, and at least one second measuring unit to measure at least total suspended solids relating to effluent of the post leach thickener. The control system comprises also a control unit to receive measurements of the first measuring units and the second measuring units. The control unit forms a control signal to a polymer dosing into the influent of the post leach thickener, and another control signal to an organic solvent dosing in the solvent extraction phase.

Provided herein is a system for producing suspensions comprising soluble metal ions. The system comprises a basket to hold a metal load comprising a permeable floor so as to allow a solution to come into contact with the metal load. The system further comprises a vessel within which the solution and the basket may be maintained while metal ions are leached from the metal load into the solution. Some embodiments of the present disclosure pertain to a system used to produce a suspension comprising copper ions. Additionally, provided herein are methods of using the system to produce suspensions comprising soluble metal ions. Some embodiments of the present disclosure pertain to methods of making suspensions comprising copper ions. The resultant suspensions comprising metal ions may be further modified to supply a pharmaceutically acceptable treatment.

Systems for improving metal leach kinetics and metal recovery during atmospheric or substantially atmospheric leaching of a metal sulfide are disclosed. In some embodiments, an oxidative leach circuit 200 may employ Mechano-Chemcial/Physico-Chemical processing means for improving leach kinetics and/or metal recovery. In preferred embodiments, the Mechano-Chemcial/Physico-Chemical means comprises various combinations of stirred-tank reactors 202 and shear-tank reactors 212. As will be described herein, the stirred-tank reactors 202 and shear-tank reactors 212 may be arranged in series and/or in parallel with each other, without limitation. In some non-limiting embodiments, a shear-tank reactor 212 may also be disposed, in-situ, within a stirred-tank reactor 202.

A method of improving metal leach kinetics and recovery during atmospheric or substantially atmospheric leaching of a metal sulfide is disclosed. In some embodiments, the method may comprise the step of processing a metal sulfide concentrate in a reductive activation circuit 220 that operates at a first redox potential, to produce a reductively-activated metal sulfide concentrate. The method may further comprise the step of subsequently processing the activated metal sulfide concentrate in an oxidative leach circuit 240 to extract metal values. In some disclosed embodiments, reductive activation steps and/or oxidative dissolution steps may employ mechano-chemical and/or physico-chemical processing of particles or agglomerates thereof. Reductive activation may be made prior to heap leaching or bio-leaching operations to improve metal extraction. Systems for practicing the aforementioned methods are also disclosed.

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.
