  • Patent number: 11247212
    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.

  • Patent number: 8833562
    Abstract: A method for separating particles of different specific gravity from a sized ore feed, wherein the ore can be coal, metallic, non-metallic and mineral ores. The method particles from the ore are sieved to obtain size fractions of different particle size ranges, after which a load of particles of a size fraction are placed in a container and fluidized by passing a fluid flow through the load of particles. By lowering the flow velocity of the fluid through the load the particles are deposited in the container in one or more layers depending on the specific gravity of each of the particles, after which the deposited particles are separated in portions of different specific gravity. The portions represent different ore content of the particles in each portion on basis of which the theoretical yield of the ore can be determined. The invention provides an apparatus to carry out the method.

The feed (2) is divided into a first, cleaned stream (C1) comprising liquid and solid particles of below a selected size limit, and a second, concentrated, stream (24) comprising liquid, and particles above the selected size limit. The apparatus (25) may be a stand alone module, part of a system with other solids and liquids separating equipment or an integral part of a solids and liquid separator such as a shale shaker. Methods of using the apparatus (25) are also described.

  • Patent number: 8678200
    Abstract: A system for dewatering a stream of slurry has a first and a second separator. The first separator removes objects above a first size, to produce a stream of primary treated slurry. The second separator removes objects above a second size from the primary treated stream, the second size being smaller than the first size. Optionally, a third separator removes objects above a yet smaller third size from the stream of secondary treated slurry. The first separator has a plurality of sieve mat supports alternately connected to a main support frame section and a movable support frame section so that the flexible sieve mat can be agitated by the movable support frame section, a collector being provided for collecting the primary treated slurry passing through the flexible sieve mat. In an optional step, water contained in the separated solids is removed.

  • Patent number: 8640877
    Abstract: Marijuana and other raw plant material such as corn is processed via a water and ice agitation method. Small diameter mixtures of plant pollen and plant debris are filtered from eight various micron filters, the filters used are 220, 190, 160, 120, 90, 73, 45 and 25 micron. The agitator tub agitates screen bags holding raw plant material and ice, to break down various parts of the plant into a process water solution. This solution is pumped back and forth between two process reservoirs, each supports two strainer columns. Each strainer column has a pair of buckets. Each bucket has a different micron filter bag supported in it. An operator can recycle the solution any number of times to achieve a desired harvest of eight (or more or less) varying diameter pollen and debris product, using one agitator drain pump and three reservoir pumps.

  • Patent number: 8562832
    Abstract: A three-stage separator system for separating the solids and liquids from a slurry includes a first stage having an inclined housing defining a liquid channel. A slot sieve is disposed over an open surface of the channel. A mechanical vibrator assembly imparts mechanical vibration to a vibration zone of the slot sieve. A slurry delivery apparatus delivers the slurry to the slot sieve. A second stage includes an inclined conveyer positioned to convey partially-separated solids and includes a drive mechanism driven at a speed to cause the partially-separated solids to tumble as they are transported up the conveyor. A third stage includes a press positioned to accept partially-separated solids passing out of the tunnel press restrictor.

  • Patent number: 8557127
    Abstract: A separator system for separating the solids debris from a slurry flowing over a spillway from a storage pit includes a horizontal conveyor horizontally disposed across a flowpath of the slurry below the spillway and including a channel defined by a pair of opposed side members extending upward from a bottom plate having a pattern of perforations formed therein. A plurality of spaced apart paddles oriented in a direction parallel to the channel are fixed to continuous conveyor drive running along the bottom of the trough. A conveyor has a pickup end disposed below the downstream end of the trough and is positioned to catch solid debris that has been carried along by the paddles and convey the solid debris out of the slurry stream.

  • Patent number: 8540082
    Abstract: A centrifugal assembly is provided that can be used in common laboratory fixed angle or swinging bucket centrifuges for the separation of material, such as parasitic ova, based on particle density. The centrifugal assembly allows the fluid level to be gently adjusted to form a meniscus without disruption of the buoyant matter, such as ova. The centrifugal assembly also enables a user to easily and hygienically collect and transfer a measured amount of a sample, such as fecal material, and to break apart and mix the sample with a floatation fluid contained in a centrifuge tube.

  • Patent number: 8443981
    Abstract: Apparatus for removing heavy material from ore in a water environment includes an upstanding tube, a reservoir, and a pulsator connected between the upstanding tube and the reservoir. The pulsator cyclically causes the upstanding tube to move downward, and fluid pressure within reservoir causes it to move back upward. This vertical pulsation of the upstanding tube effects the separation of heavy material from lighter material contained within the ore. The pulsator includes a member and diaphragm which are cyclically forced downward into the reservoir by a cam-driven rocker arm. A given downward movement of the member and diaphragm results in an amplified upward movement of the ore and the water within the upstanding tube.
