The disclosure provides a process for obtaining the purest form of Himalayan pink salt. The purest form of Himalayan pink salt is preferably in crystal in form and is substantially clear and colorless. The disclosure provides a purification process that identifies and removes solid impurities affording the purest form of Himalayan pink salt. The system may machine vision algorithms that process feedback from one or more sensors to detect and identify color or clarity, and may use one or more host controllers to remove solid impurities. The controller may identify the color or clarity and ensure consistent removal of the solid impurities.

Methods and systems for achieving higher efficiencies and capacities in sorting feed material are described herein, such as for separating desirable “good” rock or ore from undesirable “bad” rock or ore in an unsegregated, unseparated stream of feed material. In the disclosure, higher efficiencies are achieved with combinations of multiple sensor/diverter cells in stages in a cascade arrangement. The number and combination of cells in the cascade may be determined through a priori characterization of probabilities involved in sensor/rock and rock/diverter interactions, and mathematical determinations of the optimal number and combination of stages based on this probability. Further, as disclosed herein, desired sorting capacities are achieved through addition of multiple cascades in parallel until the desired sorting capacity is reached.

Systems and methods for delivering mining material to a multimodal array of different types of sensors and classifying and sorting the mining material based on the data collected from the multimodal array of sensors. The arrays of different sensors sense the mining material and collect data which is subsequently used together to identify the composition of the material and make a determination as to whether to accept or reject the material as it passes off the terminal end of the material handling system. Diverters are positioned at the terminal end of the material handling system and are positioned in either an accept or reject position based on the data collected and processed to identify the composition of the mining material.

A system for sorting objects is provided. For instance, the system includes a first and second sensor for observing the objects before and after sorting and a controller having an action agent module and a learning agent module. The controller updates, by the learning agent module, a policy matrix after sorting previously sorted objects. The policy matrix includes state data of the previously sorted objects including sensor data, an action performed by the sorting actuator, and a sorting score. The controller actuates the sorting actuator, calculates a specific sorting score based on a specific action performed by the sorting actuator, and updates the policy matrix to create an updated policy matrix including updated sorting rules. The updated policy matrix is used in sorting subsequent objects. In another example, the controller loads a policy matrix that was determined incrementally during sorting of previously sorted objects.

A powdery-material feeding device is configured to feed a powdery material to a compression-molding machine configured to obtain a molded product by filling a die bore with the powdery material and to compress the powdery material with punches. The powdery-material feeding device includes a detector configured to detect a biologically-originated foreign matter mixedly contained in the powdery material to be fed to the compression-molding machine, and a controller configured to control to remove the powdery material mixedly containing the biologically-originated foreign matter detected by the detector to avoid feeding of the powdery material mixedly containing the biologically-originated foreign matter to the compression-molding machine, or to control to stop the feeding of the powdery material to the compression-molding machine.

A material conveyor apparatus is described comprising a conveyer device having a material receiving end suitable for receiving material such as overburden or mineral at a working site, a material discharge end distal of the material receiving end, and a material transport system disposed between the material receiving end and the discharge end so as in use to cause material received at the material receiving end to be conveyed to the material discharge end; an scanning system comprising a scanning device disposed to scan the material being conveyed to the material discharge end and obtain a response from the material from which the material may be classified at least into two classes comprising at least a waste class and a useable ore class based on the response; a chassis supporting the conveyor device and the scanning device; a transport carriage supporting the chassis and adapted to cause the chassis to be movable across a surface for deployment in use.

The teachings herein relate to an inspection apparatus for visual inspection of elastic particles and to methods of inspecting elastic particles. The inspection apparatus employs at least one flap for stopping or reducing a horizontal portion of the movement of particles leaving a conveyer belt. Preferably the flap dissipates a part of the kinetic energy of the elastic particles and/or reducing a horizontal rebound of the elastic particles. The teachings herein may be employed in a method with improved accuracy of sorting elastic particles.

Techniques for processing ore include the steps of causing an imaging capture system to record a plurality of images of a stream of ore fragments en route from a first location in an ore processing facility to a second location in the ore processing facility; correlating the plurality of images of the stream of ore fragments with at least one or more characteristics of the ore fragments using a machine learning model that includes a plurality of ore parameter measurements associated with the one or more characteristics of the ore fragments; determining, based on the correlation, at least one of the one or more characteristics of the ore fragments; and generating, for display on a user computing device, data indicating the one or more characteristics of the ore fragments or data indicating an action or decision based on the one or more characteristics of the ore fragments.

Disclosed herein is a system to detect and characterize individual particles and cells using at least either optic or electric detection as the particle or cell flows through a microfluidic channel. The system also provides for sorting particles and cells or isolating individual particles and cells.
