  • Publication number: 20190390298
    Abstract: A system is provided for processing a circulating load in comminution circuit of a mineral separation process for separating mineral particles of interest from an ore, featuring: a coarse screen and an enhanced mineral separation circuit (EMSC). The coarse screen may be configured to receive a cyclone underflow having mineral particles of interest and forming part of the circulating load of the comminution circuit, and provide coarse screen feeds for further processing.

  • Publication number: 20190275533
    Abstract: A reactor system has a number of stations arranged to recover mineral particles in a slurry. The system includes a hopper to receive the slurry and barren media having hydrophobic coating to attract the mineral particles. The hopper provides a mixture of barren media and slurry to a tumbler arranged to stir the mixture in order to increase the contact between the slurry and the barren media so as to allow the mineral particles to attach to the barren media to form mineral laden media. The mineral laden media are conveyed to a rinsing station where water jets are used to wash the gangue materials off the mineral laden media. The rinsed mineral laden media are mixed with a surfactant so that the mineral particles are released from the mineral laden media. High-pressure water and air jets are then used to remove remaining surfactant from the released media.

  • Publication number: 20190265146
    Abstract: The invention relates to an apparatus for static sedimentation tests comprising a plurality of sedimentation cylinders, which are subject to the same mixing conditions, said apparatus comprises: a. A variable number of transparent sedimentation cylinders, the most common being 12; b. Each sedimentation cylinder is located inside a non-intrusive emitter and receiving sensor housing where each housing has an electronic ID card, electronic circuit boards and connection to a control system; c. A support structure containing the sedimentation cylinders and sensor housings which rotates around an axis of rotation; d. Each sedimentation cylinder has a bottom stopper and top stopper; e. Where each bottom stopper of each sedimentation cylinder is mounted on a lateral bar parallel to the rotation axis, by a fixing to the supporting structure; f. Also the sedimentation cylinders are fixed in the supporting structure by a clamping system around the top stopper of each sedimentation cylinder g.

  • Publication number: 20190009280
    Abstract: Apparatus uses engineered collection media to recover mineral particles in a slurry. The apparatus has a tumbler cell and a rotation device to rotate the tumbler cell. The tumbler cell has a container to hold a mixture of the engineered media and the slurry containing the mineral particles. The container is turned such that at least part of the mixture in the upper part of the container is caused to interact with at least part of the mixture in the lower part of the container. As such, the contact between the engineered media and the mineral particles is enhanced. The surfaces of the engineered media are functionalized with a chemical having molecules to attract the mineral particles to the surfaces so as to form mineral laden media. After the mineral laden media are discharged from the tumbler cell, the mineral particles can be separated from the engineered media by stripping.

  • Publication number: 20180274060
    Abstract: A copper/molybdenum separation processor is provided featuring a slurry/media mixture stage configured to receive a conditioned pulp containing hydrophobic molybdenite and hydrophilic copper, iron and other minerals that is conditioned with sodium hydrosulfide together with an engineered polymeric hydrophobic media, and provide a slurry/media mixture; and a slurry/media separation stage configured to receive the slurry/media mixture, and provide a slurry product having a copper concentrate and a polymerized hydrophobic media product having a molybdenum concentrate that are separately directed for further processing. The slurry/media mixture stage include a molybdenum loading stage configured to contact the conditioned pulp with the engineered polymeric hydrophobic media in an agitated reaction chamber, and load the hydrophobic molybdenite on the engineered polymeric hydrophobic media.

  • Publication number: 20180272359
    Abstract: A selective recirculation circuit has a loading stage, a stripping stage and a filtering stage for use in processing a feed stream or slurry containing mineral particles. The stripping stage forms a first loop with the loading stage, and a second loop with the filtering stage. The loading stage has a loading mixer and a loading washing screen. The stripping stage has a stripping mixer and a stripping washing screen. The loading mixer receives the slurry and causes barren media in the circuit to contact with the slurry so that the mineral particles in the slurry are loaded onto the barren media. The media is directed to the stripping stage where the mineral particles are removed from the media. The barren media is recycled to the loading stage. The stripping solution recovered from the filtering stage is returned to the stripping stage and the mineral particles are discharged as concentrate.

  • Patent number: 10013412
    Abstract: A distributed system and process for sharing a spreadsheet model. A spreadsheet to be shared is configured by defining input fields, processing parameters for the input fields, and output fields, and a template including the input and output fields is created. The template is shared with a remote user, who enters data into the input fields of the template. The input data is transferred for processing, after which results are provided to the remote user in the defined output fields of the template.
