    Abstract: A deep cleaning method for highly contaminated soil comprises a feeding step, a washing step, a first separation step, a second separation step, a countercurrent washing step, and a wastewater treatment step. The countercurrent washing step is to receive the sand water that completed the second separation step. The sand water is introduced into a countercurrent washing tank from the top, and the clean water is injected into the bottom of the countercurrent washing tank to form a countercurrent washing state. The washed sand is discharged from the bottom of the countercurrent washing tank, and the mud washed from the sand is overflowed by the rising water flow and collected to a wastewater treatment unit. Through the backwashing step, the highly oil-contaminated soil with low mud content can also be applied to the water washing method, thereby expanding the treatable range of oil-contaminated soil.

    Abstract: A method of separating a shell from a seed may involve introducing a feed stream containing shells of a fruit intermixed with seeds of the fruit into a separation column at a feed stream location. The method may also involve introducing a first volume of a separation liquid into the separation column at a first liquid addition location located below the feed stream location and a second volume of the separation liquid into the separation column at a second liquid addition location located above feed stream location. The separation liquid may flow upwardly in the separation column at a rate effective to cause the seeds of the fruit to flow upwardly with the separation liquid toward a seed outlet of the separation column while the shells of the fruit flow downwardly against the upwardly flowing separation liquid toward a shell outlet of the separation column.

    Abstract: A compact hydraulic particle separator apparatus is disclosed. The disclosed apparatus comprises an upper chamber and a lower chamber separated by a partition. A liquid fluid flow upwelling through the partition from the lower chamber is caused to mix with tangential jet of fluid flowing introduced above the partition in the upper chamber produces an upwardly-flowing cyclonic flow within the upper chamber. Particle mixtures containing low- and high-density particles and other solids are introduced into the upper chamber through a feed tube having a mouth that is offset from the center of the upper chamber. Low-density particles are immediately entrained in the cyclonic flow and swept upward and exit the apparatus.

    Abstract: This invention relates to a classifier for separating particles by size and density and a method of classifying particles by size and density. The classifier, which is also used in the method, includes an underflow outlet for conveying a first product out of the classifier; a fluidising means for introducing a fluidisation fluid into the classifier; a settling chamber for forming a hindered-settling zone, the settling chamber being in fluid flow communication with the fluidising means and the underflow outlet; a reflux chamber for forming a free-settling zone, the reflux chamber being in fluid flow communication with the settling chamber and having a cross-sectional area larger than that of the settling chamber; a launder in fluid flow communication with the reflux chamber for conveying a second product to an overflow outlet of the classifier; and an inlet conduit which projects into the classifier for introducing a feedstock into the classifier.

    Abstract: A spiral chute for mineral processing, comprising a spiral chute body (10) supported to be vertical. A radial cross-sectional profile curve of the chute body gradually rises from the inside of the chute body to the outside of the chute body. The radial cross-sectional profile curve of the chute body is a compound curve (100). The compound curve comprises a first curve segment (110) and a second curve segment (120) sequentially arranged from the inside of the chute body to the outside of the chute body. The tail end of the first curve segment and the head end of the second curve segment are connected to a first connection point (130). The included angle between the curve tangent of the head end of the second curve segment and the horizontal plane is smaller than that between the curve tangent of the tail end of the first curve segment and the horizontal plane. The spiral chute for mineral processing can not only outwardly expand and thin a high dune wall to improve the looseness of mineral particles, but also increase the handling capacity per hour, so that the mineral processing efficiency and effect are better.

    Abstract: A separation system is presented that partitions a slurry containing a plurality of particles that are influenced by a fluidization flow (which comprises teeter water and gas bubbles) and a fluidized bed. The separation system comprises a separation tank, a slurry feed distributor, a fluidization flow manifold and a gas introduction system. All of these components are arranged to create the fluidized bed in the separation tank by introducing the slurry through the slurry feed distributor and allowing the slurry to interact with the fluidization flow that enters the separation tank from the fluidization flow manifold. The gas introduction system is configured to optimize the gas bubble size distribution in the fluidization flow. The gas introduction system comprises a gas introduction conduit and a bypass conduit. The gas introduction system can be adjusted by modulating the flow of teeter water through the gas introduction conduit.
